Outstanding Business and True Bike Enthusiasts!

I recently ordered a set of custom spokes from SpokeX Bike Co., and I couldn’t be more impressed. The customer service was absolutely outstanding. This crew truly understands the importance of communication and customer care.
During my order, they ran into an unexpected hiccup when their paint gun malfunctioned. Instead of leaving me wondering, they immediately reached out to explain the situation and kept me updated every step of the way. The delay was only two days, and my order was quickly completed and shipped right after.
What really stood out was their attention to detail and genuine interest in my bike setup. After describing the color combination of my bike, wheels, and new rims, they suggested pink powder-coated spokes with blue nipples, and wow, what a perfect recommendation! The result looks incredible.
If you’re looking for quality craftsmanship, honesty, and a team that goes above and beyond for their customers, SpokeX Bike Co. is the place to go. I highly recommend them for your next custom bike project… these guys are the best in the business!

These guys were great to work with. Hooked me up with a great deal on my new Transition Regulator CX. Great communication and shipped fast.

Purchased an item from their online store. Great to work with!
