I had to change my Shimano BB71 Road Press Fit Bottom Bracket as it was goosed (rough, noisy and with a fair bit of play). I just used the cups from BB-MT500-PA Press Fit Bottom that I had from a spare I'd never used.
I'm not convinced this one will last out the year so what is the general consensus on the best value replacement press-fit for a Shimano GRX chainset?
Gusset.
Yes.
Wheels manufacturing screw together
Best, or Best Value?
Hope.

This. It's very pleasurable to have a bb so well-aligned that you can slide the axle through by hand. Still spinning beautifully with no creaks six months later.
Wheels screw together, or the 1/3 of the price copy from Token (ninja).
This one?

That ain't gonna work as it's a BB30 / 24mm axle conversion type one AFAIK, just get a Shimano one, they're cheap and last a decent amount of time.
BB30 has an internal shell diameter of 42mm (partly why they're crap as the bearings are tiny) Shimano PF has an internal shell diameter of 41mm.
That said, @martinhutch, if you couldn't slide your axle through by hand before what in gods name was wrong with your bb?
Always seem to need a tap with a soft mallet, even the screw-in hollowtech ones. I've clearly been missing out.
Cheers I'll check them out.
Just another question, what's the difference between the Shimano ones? Actual differences and peoples experiences?
