BB30 to Threaded BB

PuttyKnees

I've become very frustrated with the BB30s on my cross bike, which in the winter in full race season need serious maintenance on a weekly basis to get them running smoothly. Currently I am using Wheels Mfg adaptors to allow me to use a HTII chainset, but I'd like to get rid of the BB30 cartridges altogether and have something sensible for the conditions. I've found two options

1. KCNC BB that fits into the shell
e.g. http://www.sjscycles.co.uk/kcnc-bb30-bo ... prod33009/

2. An adaptor sleeve
e.g. http://www.ribblecycles.co.uk/sp/road-t ... 0000000000

Has anyone had experience of either of these? A search suggests the KCNC is a bit flimsy, but the sleeve can be a pain to remove if you go a bit bonkers and want to return to BB30s.

Have you looked at the Praxis Works solution?

I might be wrong, but isn't the Praxis a similar concept to the KCNC? i.e., a BB that fits into the BB30 shell. It's a solution, but does it work?

Mine works!

Yes praxis is the same idea as the kcnc but slightly different. As you thread in the drive side cup there is a collet which expands the female part and locks it in position. Seems to be the best option out there without have to loctite in a sleeve.
