Yeah iv heard off the cracking problems this is a 2009 I believe, was it around this time Andrew? bit of a gamble if so, yeah it's not tapered and neither is mine so should be ok?? BB wise I'll have to check don't know what different sizes they do
When I bought the Marin it was a large but got it as it was a bargain thinking i could get uset to the size but think iv been proved wrong it's a big bugger for throwing about and on steep descends can be tricky so fancied just swapping the frame
