crankbrothers Synthesis E Alu Disc 6-bolt 27.5" Boost Wheelset

crankbrothers Synthesis E Alu 27.5" Boost wheelset - fine tuning for Enduro

The crankbrothers Synthesis E is a 27.5" aluminium wheelset for Enduro riding and racing, which was specifically designed for the requirements of the Mountain bike. The more compliant front wheel has a wider rim for improved handling, maximum grip and more control when cornering. On the other hand, the stiff rear wheel with its slightly narrower rim compensates for load peaks, increases stability and keeps the track at high speed. The wheelset has been built with reliable Synthesis standard hubs; crankbrothers has added extra strength to the rims through a welding and sleeve joint process.
