Great on and off road
Have had this bike for two weeks now and love it. Previous bike was a Cannondale, but 26" tires. Took a bit getting used to with the extra height, but not long. Old bike had grip shifters and rim style brakes, I really like the rapid fire shifters and hydraulic brakes on the new. REI did a great job with the assembly.

I'm around 6'1" in height. I'm trying to get a general idea on what size bike to get. I'm very interested in mountain bikes and new the sport. Any help would be appropriated. I'm looking at the Cannondale Catalyst 2 27.5. Thank you.
The size chart towards the bottom of the page lists XL for someone 6'1". In the chart is also "Standover Height". Since people are not all evenly proportioned body to legs, the standover can be a better indicator for the correct size.
