morning new to the site my name is richard but go by zanrock since rocky j has been taken. i have seen alot of "do they make....or do they have" and after alot of frustration and no warm welcome from trek and sram i have decided with some help to make a 52 teeth triple crankset for my bike. i own a 2010 trek fuel ex6 and love the bike it is nice on the road [air/hydraulic suspension that is adjustable] and is great for the trails, but the top end is limited. i would love to buy a real good road bike, but i dont have the funds and the hybrids that i found do not have big gears, so i did checking and fitting and found that because of my back wheel frame width, the crank that came with the bike is the only one that fits. so the next step was talk to trek well that went not well they basically said it's a mountain bike you can't make it a road bike and that nothing was available and theyll void my warrantys etc.like i said it didnot go well [isnt that how mountain bikes became, turning a road bike into some for dual purpose] then my local bike dealer in cranford n.j. who is also a sram rep talked to them and to our surprise that to was horrible. see if i bought a walmart bike i can put what ever gearset i want on it and no one would blink at it, but this bike, the rear trailing arms are so wide and offseted noting will fit. i want more speed and more dual purpose [already mounted thinner tires 1200 miles ago] well like i said i have decided to make it myself. the project is in the works. i for now have decided to talk about it and if i find good replies i will talk about it step by step but i may need to find the correct forum for this. thanks for reading rocky
