chain loose then tight

[tkent02]

The ratio of teeth for your rear to front sprockets should always be an fractional number that doesn't add to a whole number after some small number of cycles. This makes the chain "walk" around the teeth so the same links don't keep lining up with the same teeth on the sprockets, making the chain wear more evenly. Otherwise your chain really will get tight and loose spots (link to link distances).

This is rarely if ever seen in print, but it is definitely true. If every other tooth is worn differently, the same teeth are hitting the same link every time.

I'm in Carleton Place so a bit out of town.

I used CycleMaster in Ashton. cyclemaster@xplornet.ca
This guy can do anything really well


there is also a tire specfic shop in Black's Corners. Blacks CornersTire <blackscornerstire@gmail.com>
This guy is awesome for tires. you set-up an appointment drive out he does them while you wait about 30-45 min and on the road again.

I would highly recommend both shops. Not sure if you are west end Ottawa.
