japes1275 Posted February 23, 2015 Report Share Posted February 23, 2015 Not got my head around the new fangled chain sizes but mine is 1/2 x 5/16 chain with 13 x 62 sprockets. Just counted 122 links on it but I was in a bit of a rush and as there's a half link in it I'm thinking I must have miss counted! I'll have another go tomorrow night to be sure. Mine is 13/62 which is slightly lower than it was before at 14/66. That is with the standard C15T 23t engine sprocket so overall a lot higher than yours. I found it fine but it's been a long time since I've ridden it in a section. Link to comment Share on other sites More sharing options...

broony Posted February 24, 2015 Report Share Posted February 24, 2015 My bikes fitted with 18tooth primary,standard gearbox and 14/64 gearing 428 chain. I ride first gear in tight stuff and 2nd in hillclimbs. cheers the noo Brian Link to comment Share on other sites More sharing options...
japes1275 Posted February 24, 2015 Report Share Posted February 24, 2015 Yes, don't go off my set up, I think most people go for much lower gearing than mine. Though maybe the actual gears themselves are lower in mine due to it being the original 'T' box. Mines a 1962 and previous to that the primary was 18, not sure why they changed to the 23.
