Kinesis

Hi there everyone, first time poster here. Looking for a bit of advice. I am looking to replace my ageing and battered Raleigh M-Trax as an all year bike.

I am looking at the Kinesis T and TK, probably second hand, but I seem to fall between the 54cm and 57cm sizes based on the geometry of current bike which fits me pretty well. I am 5'10" with a slightly short torso. Any advice/thoughts from owners on the sizing would be much appreciated.

Cheers, Ian

Kinesis have this bike down as a true all-rounder, with the FiveT being touted as a (deep breath) cyclo-cross/tourer/winter trainer/commuter. So is it a true do-everything bike or a jack of all trades and a master of none?
