Product Description The - Fine tuning for Enduro The Synthesis Enduro 11 I9 Carbon wheelset for Enduro and Enduro Racing features hubs developed in collaboration with Industry Nine. The rear wheel hub is characterised by its fast frictional connection, which results in particularly good responsiveness. The front and rear wheels are each designed differently to meet the specific requirements and stresses of mountain biking. Trimmed for flexibility, the front wheel is responsible for good handling, maximum grip and cornering control. Its larger inner rim width is optimal for wider tyres, for the benefit of traction, ground contact and forward motion. On the other hand, the rear wheel, focused on stiffness, provides balance, stability and tracking at high speeds. The narrower width of the rear rim supports narrower tyres, which reduces rolling resistance and improves edge grip. In addition to this 29" version, a 27.5" model is also available.
