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...

Re: 'zero reach' stem for 1.1/8 steerer

women's specific design,... thanks for the explanations, 531 colin and horizon. I've not read through all the links but would like to contribute that I believe that 559 wheels are much better for smaller people. My wife of 5.2" even has a beautiful Roberts built audax bike around 15 years old ...

Re: Chainring, 5 arms, 58 mm BCD?

Dear All,
A late response, I know, but just to let you know that the tiny, 30 T chainwheel worked very well on my tour through the mountains of lower Bavaria, Bohemia and along the hilly route along the Vltave into Prague. 2 panniers, with 6 kg each, and I only had to dismount once on a 16% incline.

Re: Ortlieb bar bag mounting cable for adapter seized

Hello and thank you everyone for your replies. I tried soaking with WD40 and Plusgas but the screw would not become undone.

Hi gaz and andrew_s, Thanks very much for your replies, especially the link to the Sheldon Brown site. Schoolboy error, apologies for the confusion, the BCD is 86 mm and fortunately Spacycles sell Stronglight chainwheels in the range of 28-38t, in steps of 2 teeth. https://www.spacycles.co.uk/m2b2s1...
