Shaun, Based on my experience and research, I love the design of the Atlantis. However, it's a pricey option so I'm considering a LHT instead. The only thing about the Trucker that concerns me is the chainstay length of 46cm (compared to the 44cm chainstays of the Atlantis). You've ridden

When I had my old Trek Multitrack re-fitted with a threadless fork it took two phone calls and a personal visit to the shop to convince them not to cut the steerer tube! I told them to stack the spacers and put the stem at the very top (so I'd have plenty of cable length). I'll admit it

Buying a Surly using the Riv sizing guideline apples-to-apples is quite likely to result in a bike that's on the too-big side. I could see that if you aimed for a fistful of seatpost on a Karate-Monkey, you'd end up with a bike that is too big.But it seems the Cross-check and LHT have

To David Craig's question: no, for Atlantis and AHH, the TT listings are actual, not effective. So with those two, the effective TT is a bit longer, but the effect is relatively small due to low angles. But yes it's true that the expanded frames (6 degree upslope ones) only list the effective
