Changing to 15t sprocket

[ghostdog]

Do you need to change the chain when you go to a 15 tooth front sprocket?

From what I can gather is you are still able to compensate with the factory.

Yup, it's a straight swap. Although if your chain has more than 20K miles on it, you might consider swapping out both it and the rear sprocket.

I'm at 13,000 miles. Chain looks pretty good too.

So I just need to get the sprocket , lock nut and washer right?

Yeah you don't need a new chain. I think I kept the lock nut as it was, and just fitted a new lock washer

And I used the old nut and old washer.

so i can only assume that going to a 17t dront sprocket also wrok with stock chain. + i will be getting new chain anyway as mine is stretched to about 2 mile now

I think a 17t would work too, it should still have some slack with a standard sprocket, with a smaller one you get more slack, with a bigger you get less. The difference amounts to something like 1/4 the length of a link in either direction. Think you can go -1 front +2 rear with a standard chain, so I think 17t on front would be fine.

Excellent might give it a bash, i dont think many have tried the 17t only a handful. I commute loads and also in the summer ride with guys who have a tad bit more top speed. Hopeing this shall be the solution to my two problems lol

 

[greg]

you need more top speed than 140?! be careful out there on the public road...

yea an average summer day isnt the same without red lining in top gear. i can out corner and break my riding friends but they always have the legs now i can stay at the front lol clever = no / fun = yes
