Louis p Posted June 4, 2007 Report Share Posted June 4, 2007 hello people,i have a old onza t-pro frame in my shed just laying around but the threads in the bottom bracket are threaded on one side, so i am wondering if i would be able to get them helicoiled some how, maybe at a engineers or something. The only reason i am asking is because i have alot of other parts and i am thinking of building up another bike to use or sell on in the future.if you have any information could you please tell me?cheers lou.

The insert is quite thin but it generally works quite well.Go ask around, it usually costs around £20. You can also loctite the BB in, but it depends on which side it is, which side is screwed? It also depends on how badly it is damaged. If it is the side that the main section containing the bearings and axle screws into then you need an insert putting in. If it is the other side, the one that the spacer thing without the axle and bearings screws into, then you will be able to get away with loctiting or super glueing it in.I would get an insert put in anyway, its not worth the risk.

But ask for a steel one, my Dad got one done and the insert was brass, OK for XC and lighter, but you may want your BB inserted a bit tighter for trials.
