Race wheels

Bontrager has a longassociation with aerodynamicistSteve Hed who took time out romproducing his own wheels todesign the Aeolus. Despite being200g above the average in this testtheir exceptional stiness madethem eel very eective orsprinting and attacking on shortsharp climbs, but the short spokesmade or a harsh eeling ride. Therim is deeper and moreaerodynamic than the others, butit didnt eel any aster or ecientonce up to speed. Their tendencyto catch side winds made the biketwitchy, and it was tricky to keep aline in blustery conditions in atime-trial, though a rider who usedthem in a road race ound merit inthis when lining himsel up or asprint. The alloy hubs use 6901cartridge bearings, but they are alittle trickier to adjust than cupand cone bearings.

Bontragers crash replacementpolicy gives a 40 per cent discounton a new wheel.www.trekbikes.com

the 2-Way fit rims acceptclincher and tubeless tyres, thoughtting regular clinchers is a littlemore dicult. The overall design,which eatures oversize aluminiumspokes and nipples, is similar tothe Fulcrum Racing Zero. Tightlyclustering the spokes like this givesthe impression that areas o therim are unsupported, but theyremained almost perectly truethroughout testing and thedefection test proved it didntaect stiness.

how we TesTed ThemBefore using them, we checked all the wheels for trueness (side to side

movement) and roundness. We also checked the bearings, with a rating of Perfect

meaning they felt silky smooth to turn between thumb and forefinger. We also rated the

hubs for how much adjusting they needed when new, and gave spoke tension before

use a rating out of 10 10 is perfect, while a score of less than 7 would have us reaching

for the spoke nipple key to tighten them. After putting in the same number of

kilometres of riding into each pair we took all the measurements again. Also, where the

tyres are very tight fitting and hard to get on easily, weve said so.

Flexible wheels can rob you of speed and cause the rim to rub on the brake blocks. To

test for acceleration we performed a series of lamppost sprints a test involving

sprinting from one lamppost to another, starting at 15mph, to see which were the easiest

to wind up to speed. To compare these results with measured readings we rigidly

mounted the axle of each wheel in a jig and placed a 15kg weight on the edge of the rim.

Then, using an engineers dial gauge we measured how much the rim bent upwards in

reaction to this and called it our deflection test. The tests were carried out with a fully

inflated tyre as these can effectively shrink the overall diameter of the wheel with a

resultant reduction in spoke tension.

traditional handBuilt Wheelslike these use rims and spokes thatare cheaper and easier to sourcethan some actory-built wheels.Hewitts wheels are built to order,and ours are based on Ambrosioshighly regarded Excellight rims,the easiest on test to t a tyre to.

The Royce Ultralight hubs arepolished and the smooth cartridgebearings live on titanium axles(ater 12 years use on another seto wheels we havent needed touse Royces next day bearingreplacement service). Hewitt uses28 DT Swiss butted spokes upront, 32 at the rear; spoke tensionwas even all-round and remainedperect throughout testing. Pro-lockbrass nipples add strength on the

drive-side, with lighter aluminiumnipples elsewhere. Being heavier,these dont accelerate as quickly asthe Eastons or Pro-Lites, but i wewere travelling urther aeld ortouring wed take these with theireasily replaceable spokes.www.hewittbikeftting.co.uk

To increase pedalling eciency,Easton uses a 25mm rim with 24spokes at the rear and, to minimiseweight, a 22mm rim with 18spokes at the ront. The rear hasspoke holes biased towards thedrive-side, so theres less disparitybetween spoke tension across thewheel.

The bearings can beaccessed easily with Allen keysand the reehub body is integratedwithin the hub, making it strongerand simpler than most otherdesigns. The spokes are attachedto the well o the rim rather thanits smallest periphery and thelonger spoke path helps dissipateshock. This makes them easier tolive with on poor road suracesthan other deep section wheels(the spokes go through the carboncovers all the way to the rim).

As with the other deep sectionwheels, on ast descents we oundourselves reewheeling past riderson shallow section wheels, but

these eel aster on the climbs thanthe other deep section ones. Thisis partly due to the deep-sectioncarbon being very thin and light,acting like a cover rather than astructural part o the wheel.Wheels bags are included.www.mavic.com

Race wheels

Winner

the verdiCt

First off, there were a lot of very

decent wheels on test here, and

as always judging it was a close

run thing. At not much more than

300, both the Pro-Lite

Braccianos and Pete Matthews

Pianni wheels proved strong

performers out on the road and

the latter can also be built to

your own personal specifications.

The same is true of Paul

Hewitt, who once again built a

pair of top quality race wheels

that should last for years. This

shows that even in the age of

branded, big name, machine-

built wheels, the bespoke

wheelbuilder is far from an

endangered species in the British

cycling world.

When it does come to the big

hitters, its no surprise that

Easton, Fulcrum, Campagnolo

and Mavic all delivered excellent

quality hoops. The handbuilt

Eastons were the lightest wheels

on test and at 600 represent

great value, but the Braccianos

just edge it as our best buy.

Mavics Cosmic Carbones also

proved a great wheel, though at a

price. But you can rest assured

that any of the wheels that

scored 9/10 wont let you down.

these handBuilt Wheels arebased around 27mm deepV-section 6066 aluminium rims,radially laced to 20 evenlytensioned Pro-Lite double buttedstainless steel aero spokes at theront, and 24 rear spokes laced in a2-cross pattern. All the nipples areheat treated aluminium. The hubshave top quality adjustableangular contact cartridge bearingsand a needle roller bearing unit onthe inside section o the reehub(to make the overlap betweenreehub and hub body stier).

The Pro-Lites dont sprint aswell as the Fulcrums and Campagsbut they have a turn o speedthats hard to nd elsewhere atthis price. They also give a

comortable ride. The rear wentslightly more out o true duringtesting but was easily xed.Roundness was slightly out romthe start but got no worse. Theresa 30 per cent discount on the costo replacing a crashed wheel.www.chainreactioncycles.com

roval Briefly aPPeared in the1980s with the rst mass producedlow spoke-count wheels or racingbikes, and the name has re-emerged as part o Specializedsempire. The chunky anodisedalloy hubs are slotted to acceptstraight-pull spokes and you canaccess the bearings or servicingusing two Allen keys.

The DT New Aero butted spokes 20 ront radial, 24 rear crossedon the drive-side were evenlytensioned and the wheels true outo the box and throughout the test.These are the most aordablewheels on test, and Specializedsays they are suitable or heavierriders and training, but we stilldont reckon theyre as good as

some in our sub-300 wheels test(issue 219). Some commonly usedtyres were also extremely hard tot. On the plus side, you get agood double wheel bag, a lietimewarranty, and a crash replacementpolicy (100 ront/150 rear).www.specialized.com

fulCrum is a company createdby Campagnolo to sate the thirstor wheels compatible withShimano gear systems, but it alsomakes these with a Campagnoloreehub. Not to be conused withthe 2-Way version that uses blackrims and is 70g lighter, theseclincher-only versions arerecognisable by their red anodisedspokes, hubs and rims. Theoversized aluminium spokes addstiness and reduce the likelihoodo spoke breakage; the back o therim is like the CampagnoloEurus smooth so theres no needor rim tape. Such is their stinessthat only the deep section wheelson test can match them or anall-out eeling o acceleration inthe lamppost sprints, and on theclimbs the Racing Zeros walkaway rom all but one o theirrivals the Easton EA90.

These are one o the best on testbut their complexity meansspecialist knowledge is required toreplace spokes or rims when theneed arises. Wheel bags included.www.ulcrumwheels.com
