Anyone know a source of well sealed, square taper bottom bracket for an early langster.

I tracked a couple of the right size down on the On-One website, but the one I bought hasn't really stood up to abuse on the road in the winter.

Anything else I can try - I assume a longer axle will put the chain line out?

Thanks

just found this:

looks like I'm going to struggle to get anything. Anyone been successful fitting a 107mm bottom bracket to a langster?

Depending on your hub you may be able to space the cog out by a couple of mm to make the chainline better on a 107. also can you switch the chainring to the inside on your cranks?

Good idea, didn't think about moving the chainring to the inside.

I'll have a look.

If anyone has found any solutions I would be interested to here.

Think some people have put external BBs on. Would be interested to know how they got the chainline right.

I've got a 1st generation Langster which is now running a White Industries BB. The original Shimano one actually lasted quite well, the replacement died within a few months so I went for the top end option. Flawless so far and at least you can just replace the bearings when needed.

Same with the original hubs and freewheel, they were pants so they got replaced by Goldtec hubs and a White Industries freewheel.

okay - I checked and looks like the chainring can be mounted on the inside of the crank so going to try a 107mm BBUN55.

so far 107mm bb with chainring mounted on the inside tabs is working well

Update:
107mm bb with chainring on the inside has put the chainline slightly out so have had a few chain offs.

I have put a 2.5mm external BB on the washer to space it out to see if it will straighten it up a bit.

I'll report back.

Velosolo have Sugino, Tange and Stronglight BB's in 68 x 103 although he is shut for holidays currently.

Looked closer - out of stock of Stronglight.

Is your chain tight enough?

Should it not all work out I went for one of the Token BB's from planet x - much better than the original BB and the first replacement which was a sugino
