Bike size differences help?
I currently got a Carrera Kraken 2013 that is a 20in (L) and i am about to buy a Cube Sting 120 29er and the cube size guide recommends an 18in. I thought given that I'm going from 26in wheels to 29 i would keep with a 20in. i can't find a shop that does the bike so I'm getting it online so i can't trial it. can anyone give me an idea. i was thinking of popping down to halfords and looking for bikes of similar size but thats still not a given.
