the 'there's no such thing as a stupid question' bike maintenance thread

I find those plastic adapters fine for installing a BB but useless for removing as they strip as mentioned above. Best to get a metal/steel tool.

Another thing worth mentioning is that the Ultegra 6800/105 5800 BB is slightly larger than the Dura Ace 9000 so the tools required are slightly different. I'm not sure about the sizing of other iterations of either groupset.

I’ve a steel framed bike that needs the seat tube reamed to diameter as I cannot get a seatpost adjusted without damaging the seatpost with scratches and zig zags.

Any recommended shop or person in Dublin who has a reamer and experience of doing this?

I suppose I should just go ask the local shop.

I'm on mobile, and I can't seem to generate a link from the Amazon app, but if you Google Adjustable Hand Reamer there's loads of inexpensive options

If you've ever tapped a hole, you can ream a seat tube

Sheldon Brown says yes

Perfectly fine. Hydraulic hose is armoured internally to withstand the hydraulic pressure of using the brake.

I'm doing a small bit of restoration on a 90s frame and groupset, the front deraileur seems to be holding the chain on the big ring instead of hte small and then shifting bigger would bring it off the end.

It looks to be seated correctly, its Braze on so not a twisted clamp. other than setting max and min limits what else should I be looking at?

I thought that might be possible. There’s very little cable length left so will get a new one and see if that helps. Thanks. In the mean time I might just open the cable and see if it will go down with no cable on it

Take out the seat post and turn the bike upside down, see can you shake them free. I just re read your post. Please ignore this

I've a rivnut gun and rivnuts, but as ever, I think I'm too far from you, Weepsie

I think the reason the cable was set too tight as it was us the shifter may be knackered. It doesn’t seem to be . I may try a . They are old ultegra 6400 so hopefully salvageable

Hi folks,

Just wondering how I go about sorting this.

I have Shimano 11-Speed Cassette and freehub wheelset that I want to transfer onto a bike with a Sram 12-speed cassette and freehub. Both disc if that matters.

Anybody know how I go about doing this?

So this lad here seemed to do it with an almost to good to be true install.
