ibis makes great bikes, i love mine, just got some new wheels for it.
over the last year ive own the bike there have been a few changes.
the dura ace 7900 crank was traded for a zipp vumaquad crank. i have both 53/39 and 50/34 rings for it. the 50/34 rings get more use.
the dura ace 7850 tubeless wheels have been swapped out for reynolds assaults. no tubeless, but the carbon rims soak up road chatter. they weigh the same and the aero is nice.
the stock san marco cyman was not giving me any love. i swapped it out for a slr, but for multiple days of riding it just makes me unhappy. so i opted for a flatter flite carbonio. i like it alot more, no weight penalty.
the foam tape has been changed for deda. its slick when wet but stays clean and feels good in my hands.
