Tekro makes the only pair of drop bar long pull levers. I believe the model is RL520. I love the XTR V-Brake and I have them on my bridgestone. I had this bike set up with Tosco bars and there was nowhere near enough reach for me. Unfortunately, youll have to go with bar-end shifters or downtube shifters if you go that route. I dont think youll be happy with the braking if you dont use a long pull lever though.
RE: cliffhangers. Grant has said that there's no need for msw's but I see what youre saying. Ive only put approx. 200 miles on the bike and it has been fine for me. I think the rims themselves are a little heavy, but if you're wanting to do touring they're really a great option.
Personally, this bike's utility was covered by bikes I already own ( A riv rambouillet for road/rando, and a bridgestone XO-2 for commuting/touring). I think I really just wanted a full rigid MTB, which this is not.
