Dublin ratios

49:18 36 skid patches and i think its about 72.5 gi or something.

Right heres a question, if you take off ur rear wheel and rotate it out of the chain ie so the same part of the chain is resting on different teeth of the sprocket, would this mean that ur skid patches would be in different spots? I can thnk why it wouldnt but just thought id ask.

Yeah that would work but you'd have to work out the ratio between your sprocket size and wheel size and then divide that by number of skid patches...

2100mm = 700c w/23c tyre

2100/36 = 58.3mm so that's the distance between your skid patches

2100/49 = 42.85mm which is the distance one tooth change would make on the tyre surface

Technically by moving one tooth it would land your new skid patch to be just in front of where your old one was...

I may be wrong but this makes sense to me ( I was shite at maths though...)

Anyone care to check?
