Re: Bolt holes in Stronglight small chainring too small

it works, it has the same bcd as the outer and if I want to make it really proper I just have to drill out the holes a tiny bit.

Re: Best oil to loosen adjuster screw in derailleur

Thanks, done all that gentle tap with the hammer, many times and trickling more WD40 and it finally came loose!

Re: Bolt holes in Stronglight small chainring too small

I've got an 86mm BCD chainring which as such fits the Stronglight Escape spider together with the outer. Thanks to Brucey I've now learned here (https://forum.cyclinguk.org/viewtopic.php?f=5&t=136906) that fitting the bolt&sleeve back to front is possible. Also, I've fitted the little chainr...

Best oil to loosen adjuster screw in derailleur

Hi, the adjuster bolt for the High gear of the rear derailleur is stuck. I've applied WD40 over the last 2 days. Should I be more patient and keep doing that? Or is there a more powerful spray, e.g. Plus Gas Aerosol? I've also put a screwdriver into the mech so the bolt does not rest at the bottom a...

Re: Bolt holes in Stronglight small chainring too small

Thanks Brucey, I think that solves the mystery. Although the holes are hardly measurable below 10 mm. Perhaps 9.8 or so, rather than 8 mm. I must have used that chainring on some different setup before rather than exactly on that crank. Would people on this forum recommend drilling the holes of my c...

Bolt holes in Stronglight small chainring too small

Hi all, I believe the holes on my Stronglight (type 7075) 30 teeth chainring are a fraction too small for the chainring nuts. chainring.JPG This is quite weird as I know I've used this small chainring maybe 5 years ago. I can still see that the teeth are a tiny bit worn. I kept and labelled the bolt...

Re: Bob Yak to dog trailer conversion

Hi Carlton,
Seat has been ordered and in July Otto will be 2. He weighs around 8 kg. I've tried the trailer and he barks so much and the seat is really cute.
I hope it all goes well. I might come back to the rack conversion when he's a little older.

Re: Bob Yak to dog trailer conversion

Hi All, Thanks for the comments, Mercalia and MickF – I’d not thought about the problem dogs might not like to be moved side to side. A lightweight two wheeler might be better Carlton Green – I’ll put that recycling box conversion on my to do list. I guess with Otto’s size none of the ready made pro...

Bob Yak to dog trailer conversion

Hi,
I'd like to adapt my Bob Yak trailer for Otto, a medium sized cockapoo.
The picture shows our first attempt but if someone can improve on this please let me know.

Re: Quill stem to A head adapter frozen in steerer

... oh dear, I only see this request for info after 6 months: so how did I get on?
Bikeshop, which is not a frame builder, accepted it and when I picked up I understood it was a lot of hard work sawing out the stem adapter. Cost £45 or so. good as new now.

Re: Quill stem to A head adapter frozen in steerer

Hi All, This has been fascinating reading, the pinned thread on this forum about seat post removal, the Sheldon Brown article, with those chemicals dissolving aluminium, Jobst Brand, and all the many suggestions made here. Still, I took it to the shop today as I don't have time to do all that, besid...

Re: Quill stem to A head adapter frozen in steerer

Hello everyone, Apologies for not replying earlier but bike issues have not been my only problem - IT issues I've had too so could not get to this forum. Thanks for all your suggestions though - I hadn't even thought about taking the fork out. However, it might be possible as indeed there's a shim o...

Quill stem to A head adapter frozen in steerer

Hi All, The quill stem to A head adapter is frozen in the steerer. This video goes through all the stages (degreaser, vinegar, tapping with hammer, and finally sawing out. https://www.youtube.com/watch?v=0GRbdnTRH-4 I've so far done only the beginning stage, i.e. taped the top of the adapter, put th...

Overinflating tyre to make rim explode

Hi All, I want to check rim wear on a bike without rim wear indicator. The advice was to grossly overinflate, but by how much? Is it twice the pressure that's mentioned on the tyre, and then for a short while? Another version was to 'slightly' overinflate, and then leave over night. Again, what pres...
