I've got a 190/55 which is what it came to me with. Some people prefer a 180/55 but this only gives 5mm more room so something must be up with the chain. I think what's happened is the previous owner changed the sprockets but not the chain which should be 110 links, mine has 108 with 2 link pieces in different places for some reason. The front sprocket looks like it's seen better days anyway so I'm going to replace chain and sprockets. Expensive as I need a torque wrench and chain tool but shouldn't happen again.
Get a decent chain tool, I cant remember which I got but it was about £50. You don't need a torque wrench necessarily, I have one but dont use it for that, you won't overtorque anything easily. Obviously it is better to have one though, just saying it's not essential.
If you are going to get a torque wrench checks the specs of it Vs what the correct torque values are, particularly the front sprocket tends to need a ton of torque you'll need to make sure whichever one you get goes high enough.
With the chain, is it completely necessary to grind the head of the pin off? I'll have to borrow an angle grinder if so.
love stories of people starting to ride and enjoying bikes. It's amazing fun! And despite having been riding for 10 years in all weathers I still make the occasional silly mistake hitting the horn etc
Took it for a little ride and it seems fine, need some better weather for a proper go though.
