Frame
Optimising a frame for disc brakes is both art and science - and as part of the process we chose an X12 quick release axle system both front and rear. The forces involved also necessitate a new fork which, together with the Attain GTC Pro Disc's tapered head tube, creates an enormously stiff structure without sacrificing comfort. This way, the rider benefits from a smooth ride and precise steering on even the longest descents. Internally routed cables give this race machine a clean appearance - a true Gran Turismo! Full mudguards are an easy addition, if the need arises - an option that we've included because we know what racers really want and need.
Components
Shimano's 105 groupset features a 2x11 gear setup. The compact chainset, with its 50 and 34 tooth chainrings, is exactly what's needed on a performance race bike. The cassette ranges from 11-32 teeth, giving the Attain GTC Pro Disc incredible climbing performance on even the steepest grades and a high enough gear to keep pedalling on the fastest descent. For scrubbing off speed, Shimano's BR-RS505 hydraulic disc brakes work reliably even in wet conditions. This race machine rolls on Fulcrum Racing 77 Disc wheels shod with Continental Grand Sport Race SL tyres.
