Curnutt F-1 XTD

Now splitting my 07' Foes DHS Mono, these forks cost £1600 new and are very rare secondhand, fully serviced by Balfa UK and used for a week, ready to roll for a season. Also available, a DHS Mono frame with Ti springs, will advertise shortly.

The refined product of years of R&D on the race circuit and hundreds of man hours later, the F1 XTD fork is the first and only downhill fork to implement the proven Curnutt XTD stable platform valve technology. The 8.5″ travel F1 XTD is a proven winner that provides an unmatched balance of pedaling platform, traction and control, especially when combined with a Foes downhill frame with a Curnutt XTD Coil shock.
