Pro bike: Jeremy Powers' Cannondale Cyclocross

By James Huang, technical editor | Tuesday, November 3, 2009 3.30pm

Cannondale-Cyclocrossworld.com team-mates Tim Johnson, Jeremy Powers and Jamey Driscoll put on a virtual clinic during a weekend's races in and around Boulder, Colorado, with dual podium sweeps in dramatically varied conditions. 

Aside from the athletic achievement, the trio's success demonstrates that aluminium is still the dominant frame material in US 'cross racing.

All three machines are built around Cannondale's top-end CAAD9 BB30 Cyclocross frame with its heavily swaged, butted and shaped aluminium tubing, the company's trademark BB30-compatible bottom bracket shell, and smooth welds throughout for a clean appearance and light 1.5kg (3.3lb) weight.

A dramatically flared 'Power Pyramid' down tube and medium-sized chain- and seatstays (the latter using a stout wishbone-style yoke) suggest good front triangle and drivetrain rigidity, while the straight 1 1/8in head tube maintains some cush up front. 

Indeed, there's nary a scrap of carbon to be found in the frame – aside from the Easton EC90X all-carbon fork – no tapered head tube, no integrated seatmast and no radical shaping, as is often found on expensive carbon rigs.

The business-like chassis is augmented by a wealth of top-range componentry used by all three team-mates, including a complete SRAM Red transmission and drivetrain (apart from the more 'cross-friendly PG-1070 cassette), Zipp's latest wide-profile 303 carbon tubulars, supple Dugast tubular tyres, Control Tech cockpit components and Fizik's popular Aliante saddle. 

The all-aluminium frame has aluminium dropouts plus a handy replaceable hanger:

Brakes and pedals differ slightly between the three riders, with Johnson and Driscoll preferring narrow-profile TRP CR950 carbon brakes and Shimano XTR pedals, and Powers opting for lighter TRP EuroX Mag wide-profile cantilevers and CrankBrothers Candy 4ti pedals (in matching green, of course).  

In full race-ready trim, Powers' bike weighs a highly competitive 7.39kg (16.29lb) but it's not the bike's stiffness, weight or fancy componentry that make it special.  Instead, it's the meticulous attention to detail that Cyclocrossworld.com proprietor – and team mechanic – Stu Thorne puts into each machine.

BB30-edition sram red crankarms are fitted with athlete-only sram 'cross-specific chainrings:

To say that the team bikes were clean and tuned would be a gross understatement; to say that they were obsessively polished, impeccably adjusted and utterly perfect in every way would be a bit more accurate but still not representative of the level of fastidiousness.

Tyre sidewalls were neatly coated in Aquaseal latex sealant, brake housing ferrules were bored out for reduced drag, and even the stainless front brake hanger noodles were custom fabricated for a cleaner cable path, adding up to some of the smoothest and lightest-feeling 'cross bikes we've encountered. 

Thorne pays an awful lot of attention to detail on his team's bikes, including boring out brake housing ferrules and fabricating custom noodles for some of the smoothest and lightest-feeling 'cross brakes we've encountered:

Toss in the sealed Gore Professional derailleur cable set and it added up to a weekend of mechanical-free racing in some decidedly ugly conditions (at least on Saturday) and three dominating performances as icing on the cake.

Whatever amount of carbon flare these machines lacked was more than made up by this weekend's performances, and few can debate their ability to efficiently – and effectively – get the job done.
