Customer Reviews

"A great upgrade to my air Bomber, much smoother and fantastic service from the TF team as usual!"

"Thanks George! Ruth @TFT"
"Purchased the coil spring conversion kit to replace the standard air spring in my 180 mm Bomber Z1. It is an excellent mod giving much better small bump sensitivity at the expense of some progression towards maximum compression. The fork is now much more comfortable on technical and/or gnarly trails. Thoroughly recommended."
