As I said in an earlier thread I putting together a winter bike. I have pretty much settled on the frame being Kinesis T2 or TK3.
The question now is what groupset to use, should I stretch to a 105 or would tiagra be sufficient for my needs. My summer bike is ultegra and I have experience of SRAM Apex on an older bike, but no experience of 105/tiagra.
Any thoughts ??
