B PTrusty and awesome performance as ever from the Tiagra range. Ordered as part of the yearly bike freshen up! Great service from Merlin too.
Mr MillarGreat value BB, I don't feel my legs struggle to turn the cranks any more than a ceramic one for instance.
DaddicoolWith the required tooling and lubes this is an easy fit for a home mechanic of modest skills. Shimano 105 and Ultegra units aren't materially different or lighter and harder to get hold of now anyway in this form (the updated version compatible with 11 speed drivetrains have a revised smaller diameter outer shell requiring a different tool or adaptor for earlier tooling). This replacement cured my clicking crankset as I hoped it would for very little cost. Prompt delivery was very welcomed from Merlin.
Mr BrowningEasy to fit. Smooth and quiet. Great price!
Mr CliffordThis will last 3000 miles, why spend more!
Mr HarperMuch smoother than my standard BB and there is a lot less flex with the bearings being so much further out. Also seems to assist with power transfer as my average speed has already increased. Highly recommend.
Mr PhillipsI needed one of these with Italian threads, easy to fit providing you have the installation tools. Works really with the my Sora triple chainset. A good buy.
Mr TrudeGreat design. Used these before, easy to install
