I test rode some tarmacs and roubaixs back in march. Thought i was a 56. Now I've eventually got a 56cm Roubaix Expert '08 nearly new, which i think is totally standard. I've got the seat back as far as it will go and I can still see the front axle in front of the bars when riding the hoods. I might be being paranoid but it feels small too. Though I don't think by much. I've just measured seat to crank and seat front to bars and the measurements are the same as for my old ali bike, which fit me perfectly. Maybe something to do with the front geometry, or paranoia. I'm wondering if a new stem might fix it, swapping the old 100mm one for a 130mm (plus a sneaky carbon upgrade ). This should stretch me out a little more, and make the difference. Any other options, other than getting a 58cm. I can't believe the adjustment needed will be that great.
