I've had quite a few carbon bikes that plow through the rough terrain, but in no way have they stood up to the same punishment I've dealt to my ENR. I stripped the ENR for the first time this week after one and half years, bearings are holding up, creaks are gone and it rides like new again. If you want something that can slap down a rock garden, can hang air, climbs well and flicks through the tech sections, then won't bitch and moan, get around an ENR.
