Reviews over the

Rotor BB30 Converter

Assembly does require the right tools, otherwise this is relatively simple. Bearings turn smoothly. As BB30 is no longer common on road bikes (I have not been able to find a replacement), it is easier to use this converter and fit a 24mm HT2.

Pros & Cons

Great product

Pros & Cons

Easy to fit. Great quality bearings. Loads better than a shimano B.B. with adapters.

Had a kcnc adapter, this rotor adapter is some much smoother , seems well built , let's see if bearings last longer , great service from mantel and good packaging

Pros & Cons

Nicely made item just need to see how long the bearings last!

Pros & Cons

Really smart looking, very smooth bearings and a great design solution. Top product.

Pros & Cons

Well engineered, straightforward to fit and robust. Tried the KCNC bb prior to this but the flimsy red plastic shims cracked and were rendered useless. The Rotor is a superior product and well recommended if you have a Shimano chainset but a BB30 frameset.

Pros & Cons

Be careful when fitting, i broke one of the plastic end bearing covers and replacements are not available.

Pros & Cons

This has to be the best adapter for bb30 bottom bracket to 24mm no more creaking, had to change bb30's every year, once fitted you can regrease and maintain for a lot longer and cheaper to replace than bb30 when needed, would recommend highly

Pros & Cons

Easy to fit,quality BB

Pros & Cons

If you need to fit a Shimano Crankset to your BB30 frame, don't mess around - just buy this one - half the price of the praxis works one, and better engineered.

Pros & Cons

spot on well engineered BB adaptor
