Axle Trouble

[Gummo]

Ladies and gentlemen, please take a look at the VIDEO and tell me if there's too much play at the bracket.
It's a bit disconcerting since I replaced the whole drivetrain no more than two years ago.

Bearing has worn. Take crank off to check it's not a cracked axel.

Bottom brackets are cheap as chips. Time to fit a new one.

Awaits a certain person to turn up. Beetlejuice...Beetl.... STOP.

At least it's Hollowtech. GXP just wear out faster than 2 years, but still cheap though.

My square taper cotterless has been fine since 1983. Just saying . . .

I've had had to replace square taper cottarless bearings over the years. Just saying.

I get 2-3 years out of a square taper cartridge BB on my commuter ! Just saying.

TBH I run Square taper, GXP, Hollowtech 2 and FSA Mega Exo.

The Mega Exo got the bearings replaced when I bought the bike second hand, and that bike get's crap thrown at it, it's been fine - CX bike. The GXP - changed the SRAM to a Praxis, as the bearings are easier to replace.

That bike is my MTB and when it comes out it's usually in atrocious conditions, and after a big ride I usually need to remove the chainset, pop the seals and clean out the BB bearings - that's life. Bearings get replaced if rough.

Square Taper cartridge - just get's fitted until you get play in a bearing, simple and cheap to change.

The ones I've never touched are a Shimano UN91 and UN71 BB's fitted to my vintage road bikes. OK they don't get used much now but they were fitted from when the BB's came out on the market.

All are pretty easy to fix, it's no big deal.

My peace keeping tank has a UN71 bottom bracket.

Remember to check the cups!

I did. Sadly weather ingress over time respects none of this.

Someone forget the grease? :-)

 

[Drago]

I certainly didnt, bit even marine grease can only do so much.

Unobtanium UN71.

I have the also double unobtanium UN91 Unicorn's horn !

Marine Grease is as as good protection as you can do, but it's can only do so much. I use it !
