"Out of the box the side pulls will have more stopping power. Cantis are pretty sensitive to setup and out of the box with the stock straddle cable they don't stop super well.
However, the trade off for better stopping power is less rim…"
Funny... I had a 42, single ring, in 2007. Always felt I wasn't able to keep up on the road sections, and wished I had the bigger ring. Went to Nats and got outsprinted (for 27th...) Went to the 46/38 for 2008 and had one of my best seasons ever. I've been thinking of going to a 44/36, though. Been struggling a tad this year with the climbs. Got married, took time off, had family in town... and it's all crashing down now!
See you on the start line somewhere along the way!
