Hi, I'm not sure if this forum has dealt with temperature impact on singlespeed and fixed gear chains, although a search on "temperature" and "chain breaks" didn't yield anything. This year is the first time I'll be riding my fixie in winter. I like my chain really tight and it worked well throughout the summer. This week, with the temperature going down by about 20 degrees F, I had my first chain break. I'm wondering if the two events are related. If so I guess I'll move the back axle a smidgen to accommodate for chain contraction. Does anyone have a similar experience? Thanks!
