I'm 5'5, would the 170mm be better? Is .1 of an inch really gonna make that big of a difference?
Jenson has a sweet deal on the 175 but don't have the 170's.
Bike is size small.
Blue Sky Cycling also has a sweet deal on some 170mm XT's. Ordered some for my wife last night. She's 5'2" and doesn't like my 175s. IMO you'd be happier with 170s but probably would be fine with the 175 as well.
