Thanks again for the amazing service ! I cannot thank all the guys at SpokeX for building me a killer set of wheels. They were super easy do deal with and I would gladly support them again ! Super great experience and I think I will have to order another set for my DH bike !! You guys rock !

After having wheels backorder for nearly 5 months I canceled the order and ordered new wheels through SpokeX. My wheels arrived less than 2 weeks later just in time for my Bentonville trip. These guys earned my business for sure!

Dope shop, staff is on point .. Got some good info on wheels, hubs, etc. They even worked on the same wheel off my bike three times until they figured out it was the off brand valve I used that was causing the slow leak...replaced it with a Muc-Off and been rolling good since.
