Be gentle , I'm learning ;-)
I need to buy a new bottom bracket bearing set for my gt fueler 1995.
When I look at options it offers 19mm or 22mm .
I've measured the threaded part of my 1 piece crank and its 22mm outer diameter .
Also I note from my model its a USA size bb.
Does this mean I need a 22mm size bearing set ?? (I realise I need the USA option )
Seem to be more 19mm on offer ...
Don't want to buy the wrong one 😉
Cheers in advance

Glenn 19 should be fine. I'll pop one over to you when I find a brake :daumenhoch:

Sounds like your looking at 3 piece crank bottom brackets and you have a 1 piece crank :)

Thanks Nick 😊
What does the 19/ 22mm denote on the descriptions online ?
Is is the diam of the threaded part of the crank ?
-
it refers to the diameter of the axle. Most 3 piece cranks use either a 19mm or 22mm sliding axle.
There are some exceptions. There are 20mm, 24mm and some imperial sizes like 7/8 and 1 inch.
Pop up a pic of what you have.

Need to learn the lingo OPC .. One piece crank ?? ;-)
With verniers its 22mm on threaded part ..
Are the sealed ones worth the extra ££ ?
Cheers

Yes sorry One Piece Crank :LolLolLolLol:
Any bottom bracket that states One Piece Crank will fit. As for sealed, yes they are better but only to a point, depends how hard you're going to ride it. Tange/tioga ones are probably the best value for money

I guessed that from his 1st post, It sounds like he his looking at bottom brackets for 3 piece cranks, Thats where the 19mm and 22mm came in.
Bearing sizes are not normally quoted on OPC bottom brackets.

I often wonder if this hobby is becoming a fashion statement it's a opc bb did you ever ride?
-
That's helpfull .
Why don't you just not bother .
Thanks to other posters , I got it sorted ;-)

One piece cranks usually quote the thread size like 24tp than the bearing /axle size often quoted on three piece cranks.
Good on you sticking a one piece on. I do like a good old redline flight but all that spacer and alignment bollox I'm having a break from that!!!!
