BB30 converters options to allow shimano cranks

byrybak

Hi all
What is in ur opinion best option to convert bb30 I’m fed up with replacing bearings every few months!
Maybe good reliable bearings that u have used?
So far this one seems to be getting best reviews https://www.mantel.com/ie/rotor-bb30-converter&utm_source=google&utm_medium=shopping?gclid=EAIaIQobChMIt5CzmMW32AIVy7_tCh0EWwBsEAQYBiABEgJ1m_D_BwE

I've been using the Wheels Manufacturing version for the last few years and happy enough with it, no big gotcha's there.

Just be careful which convertor you buy, the rotor should be fine for all BB30 bike looking at the pictures but for example a praxis works won't fit my Felt because it has a carbon BB shell with a stepped opening to hold the BB30 bearings, not an alu tube with clips.

I’ve been using an FSA threaded sleeve on my Felt F5 for the last 3 years without any problems.

Use that Rotor one in my CAAD. Very impressed by it. Used the WMFG adapter cups beforehand and it was a creaky nightmare. Especially in warm weather.

used the rotor for several years now in my slice, been rock solid

I've a felt which has a BB30 and I had to go through a couple of different sets of bearings until an (ex pro) acquaintance told me to get these:

Been silent cycling ever since. They are in the bike about a year now and been through all sorts of crap weather. Running perfectly smooth and above all, no creaking. May be an option for you.

I have the Rotor one and wouldn't recommend it, a creaky nightmare in my Specialized Roubaix. Should have gone for the the FSA threaded adapter and give the pressfit the heave ho but from reviews I cant use the FSA one with internal cables

FSA threaded adapter then a standard Shimano BB for me, just remember it is a semi perm conversion, I wouldn't like to be trying to remove this adaptor - I glued mine in with Loctite 638. 
Best thing I ever did

Ordered the rotor converter today, will see in few weeks if it was right choice! Thanks to all for advice and reviews ��

Mine was bonded in with 638 also...it’s never coming out.

Resurrecting this, how are you getting on with the Rotor adaptor?

Over the next few days will be replacing the rotor in mine with another rotor, zero complaints over the last 4 years of using the rotor so going with it again.

Just to add another option to the mix. I'd have a look at Hambini. One piece bottom brackets machined from a single side which means tighter tolerances (parallel & angular). Parallel and angular misalignment are the main causes of creaking in a bottom bracket.

The hambini bottom brackets are expensive but you'll only ever have to replace the bearings and not the sleeve.

As a side note I'd steer clear of any bottom bracket that FSA produce. It's well known that FSA use poor non branded bearings. Main issue here is the tolerances on the bearings rather than the rolling resistance or life. I've seen plenty of people scoring their crank spindle as a result of this.

That Hambini looks interesting, not being very proficient with the work involved in changing it, is there a shop mechanic that would do this (Dublin area).

Any bike shop should be able to do it. It's installed using a standard bearing press with a bit of grease. I believe there are a few videos from the guy that makes them showing how to install. Seems about as easy as every other Pressfit bearing.
