Installing a new bottom bracket can give your bike a new lease of life after moulded seasons on the roads & trails. However, pressing the bearings into the frame incorrectly can damage both the bearings & the bottom bracket shell. The X-Tools Press Fit Bottom Bracket Press uses precision bushings to guide the bearings into the shell easily & accurately, helping you get the best from your frame & bottom bracket. Supplied with bushings to fit BB86, BB30 & BB90 press fit bottom bracket standards, the X-Tools Press Fit Bottom Bracket press is essential for any rider who builds & maintains their own bikes.
