Not the most bling upgrade, but if you've suffered from a creaking BB, you're going to love a Hope BB. Far superior to the OE bottom brackets most bikes are sold with, and as close to a fit-and-forget-it solution as you are going to find. Hope press-fit bottom brackets feature high quality sealed cartridge bearings, the best match to Scottish trail conditions we've found. Options to suit 68 mm, 73 mm, 83 mm and 100 mm bottom bracket shell widths. Available to fit 24 mm and 30 mm crank axles. Available with replaceable stainless bearings for greater durability. Truvativ conversion kit available separately. Cups pressed in and held in place by a screw-in centre tube to prevent slipping and play. Easy to service and replaceable parts. Weight from: 112g.
