granfondo GF02 Disc endurance

Cyclocross all-rounder with disc brakes.

With the BMC GF02 Disc, you have an aluminum bike that can ride the road, the trail, randonnée, race cyclocross, and commute, all with equal mastery. With its lightweight frame, plenty of tire clearance, clever accessories, and disc brakes as integral part of the design, the GF02 disc works best on any road, even if it isn't a road at all.

Concept

Versatility: The granfondo GF02 disc is designed to be the most versatile road and cyclocross bicycle. With massive tire clearance and ‘cross geometry it is fully at home on a cyclocross track. At the fork tips and dropouts are eyelets so you can armor up for a wet day or mount with light supplies for a sixteen-hour ride. Or do both and turn the bike into a super commuter.

Confidence Inspiring: Lateral and torsional stiffness are maximized by using an oversized down tube and massive chain stays. Precise cornering is achieved by a full carbon fork design with an oversize crown matching the tapered head tube. Disc brakes are an integral part of the design with 160mm rotors front and back for powerful and consistent braking no matter the conditions.

Vertical Compliance: The heart of the design is the granfondo platform, complete with TCC Tuned Compliance Concept and featuring Angle Compliance, allowing for generous vertical compliance front and rear by introducing bending into key elements of the frame, such as the seat stays, the seat post and the fork drop outs. The GF02 disc was designed to use up to 35 mm tires, knowing that bigger tires add even more vertical compliance.

TCC

tuned compliance concept

BMC's tuned compliance concept (TCC)

Optimized ride qualities in carbon products thanks to BMC's Tuned Compliance Concept (TCC).

With a neat combination of different carbon fibers and their alignment, and by applying stepped tube profiles, we achieve increased vertical compliance while maintaining high levels of lateral and torsional stiffness. The TCC zones on the frame, fork and seatpost boost the comfort rating noticeably. TCC significantly improves the ride experience by slowing the onset of rider fatigue and through precision handling and efficient power transmission.

tapered steerer

tapered steerer

Tapered head tube

Tapered head tube - with a minimum increase in weight, a disproportionately higher fork thickness results.

System integration

natural born postmount

Brake mount is directly bolted to the rear triangle.

Direct assembly of the brake caliper to the frame with no need for an adapter means improved braking power transfer, especially under demanding conditions.

triple butted

Triple butted tube set

Triple-butted tube set made of a 6000 alloy. Triple-butted means that the tube has three different wall thicknesses.
