About Mortop

Q & A


The Mortop External Road Bottom Bracket has super smooth steel bearings and a lightweight construction. It features 7075 forged and CNC machined alloy cups with an innovative internal spline for fitting. This gives the Mortop BB an extremely clean external appearance and prevents the external surface being marked from fitting. A clear plastic centre sleeve with double o-ring seals prevents water ingress.

Use Shimano TL-UN74S Cartridge Bottom Bracket Cup Installation Tool or similar for installation. Replacement bearings are available and can be easily replaced without removal of the BB cups making these bottom brackets a great value investment.

Fitment: BS Thread - 68mm - Shimano compatible cranks
