, Ready to Budget road bikes just kee Richard Grigsby looks at t born-again racers, leisure ri t hat want something fun fo T he three bikes featured this mon th faU int o that catego ry bet ween che ap a nd cheer ful ent ry-level machi nes and the finely tun ed race bike. It's a category that is growi ng and the q uest io n is - do the rapid developme nts in afford able ro ad bikes mean that they are now worth considering by riders ot her than the novice? Is it o nly those o n a tight budg et that need look at this categor y, o r have manufact urers now op ened this highl y co m petit ive £600 price po in t to bo rn -again racers o r time-r estr icted (by work O ( family) weekend warriors? Ad d itio na lly, sho uld the financially well off leisure and fitn ess riders lo wer th eir sights (and per haps risk some loss of status) by delving into this wo rld of budget ro ad bikes in th e process freein g up cash for valuable upgrades? Th e Hewitt Pro Am has a good spec alum ini um frame, carbo n fo rk BIKESHOP and Campagnolo Xenon components package (gro upset ). The Monoe Te2 is also made fro m lOOO-series aluminium, this time triple-b utted, with Xenon groupset and carbon forks. The Specialized Allez Alis based o n a compact (slop ing top tube ) aluminium frame, and dev iates further fro m the other test bikes by having an alu fork and a Shimano Sora . FRAME Hewitt (;) Monoe 6 Specialized (;) The Hewitt has perfect headtube alignment and good frame geometry giving ne ut ral steering traits mea ning the back end follows the fro nt end and the rea r wheel sits squarely in the fram e and is easy to get in and out. The Taiwanese carbon fork is also perfectl y aligned, but both frame and fork weights are fairly high at 179 1g and 685g respectively despite having an aluminium fork steerer tube. Frame is TI G ~ weld ed an d the paint job lively in ubiq uitou s European budget alloy style. Frame geomet ry is carried ove r from sma ller sizes, so th e seat ang le (74°) is prett y steep for a mi ddle-sized frame . The top tube is marginally shorter tha n the seat tube, whic h is no rmal for bikes from the Wo rld Bible of Pramebuilding (W Bf) . Fra me expert and Midlands bike dealer Paul Hewitt stresses that he sets up every custome r on a jig before he recommends any particular size. 'If the bike doesn 't fit, what's the point,' he says. Altho ugh he produces mid to high-end b ikes, he can also cope with entry-level and the Pro Am is a goo d demonst ration of this. The Mo noc uses an oversize, centrally fat, down tu be, similar to some Bianchis. The tubes are tri ple butted and T IG-welded with file-sm oothed joints. Co upled to a deep Azur blue and sculp ted carbo n fork, the Monoe looks every bit the copyc at pro racer. The compact frame version (unavailable at the time of our test) looks stunn ing for a £600 bike. Head tube, rear triangle and for k were all perfec tly aligned on o ur test bike. Left: The ITM barsandXenon levers are good qualityfor a £600 bike 56 ICYCLINGGlEl 'Paul Hewitt sets up every customer on ajig before he recommends a particular size' April1001 Main bike test The geometry is quite extreme for an entry-level bike. Like the Hew itt, the seat angle has bee n carried over from sma ller bikes an d this time is very steep at 75°- sim ilar to Triathlon and Time Trial bikes.The 73.5° head ang le is also steep for a sma ll frame, red ucing trail to 56m m. We are in for med however, th at the compact geometry is much more standard with more relaxed seat and hea d angles. The Allez is mad e from what Specialized call Al Prem ium Aluminium, wh ich is probably 7000-series alloy beca use it weigh s in at 187 1g, only ma rginally more than the 7000-series Hewitt. Th e simple but elegant frame is T IG-welded to the us ua l high (Taiwanese) standar d an d paint ed blue and white in team colours. Although the spec is a bit d ull, the looks and name mu st gua rantee success for this well rep uted brand. The fork has aluminium bla des tha t are bonded to an 1 1/8in Cromo stee rer, pro bably expla ining the weighty, but carbon fork stan dar d, 707g. Th e geometry is very grown up for an entry-level bike with a healthily lo ng top tube (57cm) for a medi um sized seat tube, com pared to Giant's mediu m TCR. A seat ang le of 730 an d a head angle of 72 is also no t goi ng to upset anyone, especia lly with a very low fo rk rake (37.5mm) giving a generous 72mm of tr ail. 'The Monoe is aU left: The Monoc's ze ro st ack hidden headset Aprilzooz ready to race from the crate but upgrade the brakes first' CYCLlNGI1!!lJ I 57 BIKESHOP HANDLING Hewitt <:} Monoc 6 Specialized (l) Th e Hewitt's rid e is dominated by th e heavy wheel and tyre pac kage so accelerati on was slow and hi ll work impeded. Subst ituting a lighter and stiffer set of wheels would no doubt comp letely cha nge th e feel of thi s bi ke as the ove rsize alloy fram e and ca rbo n fork are th e rig ht ingred ients for spirited riding. This comment ca n be app lied to mos t chea p aluminium frames: They all feel very 'dead' The ride is stiff bu t unrewarding. Lacklust re compared to any steel frame made from anything above the most bask Cromo rubeset. My initial riding notes for the Monee read:' Bit vaguedown hills. almost like it's got a rear puncture.' Looking at the steep (73.5°) head angle coupled to 43mm fork rake and minimal trail (56m m) , it's no wonder this bike felt a bit sketchy. I am told that the Compact versions have more 'norm al' WBF geometry. My no tes also said that it 'Sp rin ts like Merckx Flyer!' which is highly complimentary. The tru th is that the Monee made you feel like spr inti ng whereas the Specialized made you want to ride steadily and the Hewitt loo k for do wnhill s. Compare d to the ub iquito us carbon fork, the Allez's alu min ium alloy fork act ually feels lively.When th is liveliness comes with some shock absorptio n, it makes th e Allez a ser ious conten de r for longer di stan ces. Specialized market th e A llez as being an all-rounder and I would agree that th is bike could m ake a decent credit card tourer, chaingang chariot and leisure bike. True, th e ride is not th at inspirin g b ut th is could be per fect for begin ners who d on 't want any su rp rises. 58 ICYCLlNGI1!!Il April2002 Main bike test The rivals ORBEA ASPIN £150 The Aspin is based on a JOOS-series aluminium frame and aluminium fork. It uses a Xenon groupset and Mavic MA3 wheels. much the same as the Hewitt and MOROC we tested. Sizes run from 48 to 60cm in many increments. and top tube is horizontal A triple chainset upgrade is aYailable for an extra 00 making the range very versatile. A compact Euskaltel (Orange/Yellow) team colour with airbrushed paint finish is available at £499 wrth a Shimano Sora triple groupset. If you have a bit more to spend, you could go up a grade to the Naranco for £650. The ertra money gets you a Zeus carbon fork and a Mirage groupset. For more details, contact East Coast 'ft' 01778 142 207 GIANT OCRlIlI69S/£lll Voted budget bike of the year in 2001. the OCR has a very wide appeal. As. a time trial bike the OCR frame is stiff and reasonably light. As an all-rounder the triple WHEELS Hewitt ti Monoe f) Specialized 0 The wheels on the Hewitt are iden tical to those on the Monee except for the tyres. The Schwalbe Blizzard Pro tyres on the Hewitt have a m uch 'deader' feel tha n the M ichelin Axial Pros on the Mo noc. True, th e Schwalbes have a kevlar belt un de r the rolling sur face tha t ma kes t hem more winter-proof, hut th is kevlar belt also gives a sluggis h response - because th e belt is resistan t to bending so the ryres ro ll more reluctantly. The Mon e e had a no isy rim joi nt that knocked the fron t brake on descents. Th is is very un usual because Mavic mac h ine their braki ng sur faces after welding the rim join t. Apart fro m this o ne-o ff problem . th e wheels are race-quality, includ ing th e top Axial Pro rubber from Mi cheli n. T he hubs have been u pgraded one notch to Ca mpagn olo Mir age and the spokes are . doubl e b utt ed stainless. Specialized fit the ba sic-looking Ritchey b rand ed hubs to Alexa rim s on the Allez. Th e b lack-painted qu ick-release mec hanis ms are pa rticul arly chea p lookin g. Spokes arc b lack painted, plain gauge stain less and the tyre choice is from Specialized's highly rated but still u ncom mo n Turbo series. T his tyre comes with a fold ing bead and kevlar belt under the rolling sur face. April 1001 chainsets and adjustable stem put this bike into the Specialized Allez category. OCRl has a Shimano Tiagra groupset and OCR] has the Sora groupset, other than that there's no real differences, apart from colour. Sites are small, medium and large with 53. 55.5 and 58.Scm top tubes. Contact Giant UK 'Z!' 0115984 6000 www.giantbicycles.com UMOND NEVADA OTY mo The Nevada is made from Reynolds 525 Cromo steel wrth an alloy fork. EQUIPMENT Hewitt ~ Monoe 0 The gear shifters are Shimano's Sora and there is a choice of either double or triple chainset at no extra cost. There is a full range of sites from 47 to 61cm with the 47cm being of interest to women because it has a short, 5Ocm. top tube length. When we tested the Tourmatet we found the handling to be particularly sweet and natural making this bike a good choice for beginners. Contact Trek Bicycle Corporation 'Z!' 01908282 626 www.trekbikes.com Specialized 0 The Hewitt uses the new Campagnolo Xenon groupsct - a welcome newcomer to the Ergopower family. Whe reas all existi ng Campagnolo shifters use multiple d own -clicks on the front changer. the Xeno n has two clicks only, both necessary to derail the chain fro m the ou ter ri ng to the inn er. T he reaso n seems to be th at Xenon combines th e double and t riple co mp atib ility o f ot her Ca mpag gro upsets with th e fron t indexing us ually associa ted Shimano groups. Fit a t riple and the change ind exes on on e click. Even as a double th o ugh we th ink this d esign deviation is a goo d on e, becau se begi n ners will have less to th ink about d u rin g th e fam iliarisation stage. Th e gear rat ios on th e Hewitt arc th e same as on the Mo nee and sho uld be su itable fo r all-ro un d cyclists unde r all co nd itions, apa rt fro m parti cularly hilly terrain . If th is b ike was to be u sed for time t rials a 12-2 1 cassette woul d be better t han th e 13-23 su pplied becau se it wo uld up th e top gear slightly and close a few gaps within th e m id to low end o f the gear ran ge. Th e rest of t he Hewitt's equip me nt is very well spccccd for a bike th at costs £600 with ITM bars and stem, DiaCompe head set, Ritchey scat post an d Selic lt alia sadd le. I'm sorry but r don't see wh y begin ner s or leisure ride rs shou ld have th eir .... CYCLlNGI1!!Il 59 ~ BIKESHOP safety jeopardiscd by inferior brakes. The brakes on all these bikes are poor. Yes, it does encourage up grad es but thi s sho uld not be for safety reason s! The performance of the no -name stoppers on the Speicalized - which are the worst - might be no surp rise, b ut th at of the Xeno n b rakes o n the Hewitt and Mo nee is. Co mpared to higher-ran ge Ca mpag calliper brakes,the Xenon dual-pivots are inadequate. A change of brake blocks and cables may help (thoug h better blocks made little difference when we tried them), but again, why should it be necessary? The Monee uses Xenon compo nents like the Hewitt and it shares a criticism. The down-shift, from larger to small sprockets,is a little slower than other Carnpagnolo but this could be attribu ted to several things - a stickygear cable makes a real mess of slick shifts; cables that are too long or have excessiveS bends in them don't help; any invisiblekinks or crimps will also impede dean shifting. A sea of Monee-branded compone nts meets the eye and it all seems very acceptable. even on their £600 'Sport' model that shares many components. The Ahead handlebar stem and decent wide anatomic bars givea good, stretched out, riding position. Monee's zero stack hidden headset is made by Cane Creek and they use their own-branded saddle and seat post. Gear ratios come from a 53/39 front end and a 13 to 23. v-sp eed cassette which should be just right unless you are a massive gear pusher. For a large company like Specialized, the Allez lags a long way behind the Hewitt and Monoc in the specification rankings. The Promax brakes were pretty abysmal with a lot of force needed to stop. Other equipment was generic or in-house, which is OK for a competitively priced up-and-coming bike but disappointing to see plain part s on a good-looking frame like the Allez. The Body Geometry saddle is a nice touch in an oth erwise low-end offering. On the good side. the Allcz comes with a choice of double or triple chainsets, which givesbuyers a range of sporty or practical ratios. If you are not worried about the slightly wider pedal placing, I would go for the triple as the 52142/30 rings givea good spread of gears compa red to the 53/39 double which is coupled to the same 8-speed 12 to 25 cassette. The Sugino crankset looks characteristica lly dura ble and the dera illeurs are Tiagra coupled to Sora shifters which, having a Campagnolo-style shift, is a good comb ination. 00 Triple-butted: Whereas double-butted originally meant that the tube wall thickness at the joined ends of the frame tube was double the thickness of the larger central section, tr iple-butted gets used to indicate a two-stage reduction. Hence the 1.5mm or so end wall thickness reduces down to O.9mm or SO before a further reduction to O.6mm in the central section. 7000-series alu: This is the best range of standard aluminium to use on bicycles. It displays better machinability than 6000·series and is a little lighter as well. Steerer tube : The steerer tube is the elongation of the forks. Nowadays, with the popularity of Ahead headsets, the steerer tubes don't have to be threaded as they pass right through the headset, rather than being clamped into it as with the old-style screwed headset. Steerers can be made from steel, alloy, carbon with alloy crown or all-carbon fibre. Plain gauge : A tube where the wall thickness is constant, rather than tapering down from the ends . Aluminium versus the rest All of the test bikes are made from aluminium alloy, which is around a third the weight of steel and comes in chunky section tubes; hence its popularity. The chunky tubes aren't there just for show; they go towards making a stiff frame, which reduces the amount of flex the joints experience. This not only makes these bikes good at power transfer and safe to flick around corners, but it also prevents them from fatiguing and breaking. Aluminium is more expensive than steel to produce and to heat treat after welding. Heat treating is necessary to de-stress the frames and to reduce brittleness in the joints, which can 60 I CYCLING" . ·fj lead to cracks in the tube immediately next to the welds. If aluminium does crack it tends to do so without warning, which is not good for bike frames, hence the heat treatment and oversi~ing, A lot of people are sold aluminium on the basis that they presume, and the retailer often goes along with this belief that. it is light. Although aluminium is around a third the weight of steel, it only has around a third of steel's strength so it needs beefing up in order to survive the road shock and repetitive loads from cycling , And, yes you guessed it, adding three times the wall thickness boosts the frame weight to something approaching that of a good-quality steel frame . Steel is still favoured by many custom builders although the popularity of aluminium has put quite a few of these either out of the business or forced them to concentrate on other materials. Steel is generally less complex to build a bike frame with and can be joined by lugging and bra~ing, with molten brass, brazed without lugs or welded. Some steels even exhibit almost magic qualities and increase, rather than decrease. their strength in the heat affected zones around the joints. These are called air-hardening steels, as the frame must be allowed to cool naturally after joining, rather than quenched in water or oil. Steel can build into a very light frame but these tend to be unsuitable for heavy or powerful riders because they can be very 'whippy' due to the flex of the thin tube walls . Carbon fibre is a very underexploited material in the bike world. The ability to mould it and add or omit layers means that carbon fibre is much more flexible than any other tube, But manufacturers have not found an economic way of moulding carbon for use as a frame material, although it gets used on most road bike forks these days .

Only one, in our opinion could be raced straight from the crate - and only then with a brake upgrade . but they all need that. Leisure riders would be best off choosing the Specialized Alle:r. with a tr iple chainset . The alloy fOR is very comfortable (unlike most carbon fORs) making it ideal for longer rides.. In this case. actual Kores are not totally relevant for those seeking an all-rounder, The Hewitt is a completly different kettle of fish and would make a much more serious bike given a few upgrades. The wheels are just too dull and would benefit from some livelier rubber at the barest minimum , if not a set of Campagnolo's Factory -built Siroccos , which would add on another £lS0. Whereas the Campagnolo Xenon shifters are perfectly suited to born-again racers o r leisur e riders, r reckon the upgraders would want the more comprehensive shift mechanisms found on the existing range - even if it means just going up to the Mirage. The Monoc is ready to race but the brakes should be upgraded to Centaur, as should the Hetw itt's . The wheels are also an upgrade option for those with money burning a hole in their pocket but th is bike does feel yery exciting as it is. True, it has a £7Sadvantage oyer its test mates but this is mainly spent on the lovely-looking carbon fork . Although this price differential makes the Hewitt very good value for money, The £600 Monoc 'Sport' would still give this bike and the Specialized a run for their money. ~ HEWIn ti Great potential budget racer in need of decent tyres and brakes and possibly a wheel upgrade MONOC ti Fine pedigree. poor brakes . See the compact version before deciding which is for you. Doesn't descend as well as the other two. SPECIALIZED ~ Slightly disappointing for a big name , although all-rounder appeal is still good CYCLlNGI1!!lJ 61
