Great service, great wheels!

This review is actually for the same wheels but with the 50mm rims, just the automated feedback thing thinks I bought the 40mm ones because that's what I ordered. When I realized that there was an option for 50mm rims, I followed up with an email and the folks at Fyxation replied in a jiffy and were happy to swap the 50 for the 40. They did some other order customization too. Great service and quick turnaround on the build. The wheels themselves have been awesome. Wrapped 'em in 2.8" rubber and put them on my Salsa Mukluk and have been bombing rocky and rooty singletrack and they've stayed true.

Exactly as ordered, quick delivery

These wheels turned my Pivot Les Fat into a 4 season ride. The wheels were reasonably priced, came straight and stayed straight after some pretty serious shenanigans. I bought another set of wheels from Fyxation with wide rims for dedicated snow riding after seeing how nice these were for the cost.
