Hope Pro 4 + Fortus 23 Disc 6-bolt 27.5" Boost Wheelset

The Fortus 23 Pro 4 27.5" wheelset by Hope - for Cross Country riders

The Hope Fortus 23 Pro 4 wheelset in 27.5" is based on a rim that is 23 mm wide on the inside and was designed for Cross Country and Trail use. Its name is reminiscent of the Latin adjective " fortis" = strong. The Fortus 23 was manufactured completely by machine and by hand at the company headquarters in Barnoldswick (UK). At the heart of the wheels are the proven Hope Pro 4 hubs (Boost) with increased flange diameter.

Note:

The shipping time for wheels with coloured hubs (all colours except black) can take up to 8 weeks.
