Something second hand
... I buy my bikes second hand because they are cheaper, i am only going to wreck them anyways, most decent bikes dont see a lot of use and a lot are sold on after only doing a few miles as people cant get to grips with them. I bought my Cannondale in my sig for £600, its got a full dura ace groupset, carbon profile design TT bars, alien carbon seatpost, CODA cranks and campag pro fit pedals.
If bought new that would have cost me an incredible amount of money, the guy who bought it bought it new and built it up, did a few 10 mile TT's decided he hated TT's and put it on
ebay.
You tend to get much more for your money if your willing to accept a few chips, a bit of wear on the drivetrain and some scuffs here and there.
