Seatpost Clamp
MTB techs - 74deg. seatpost, 48-36-26 crank, derail???
KHS FR1500 frame, 74 degree seatpost, Shimano XT 48t-36t-26t crankset, XT M761 Derail totally doesn't fit, I think it's made for a 63-66 degree angle. I can adjust it to shift reliably, but the chain drags on the bottom of the derail in the 26T chainring. Lowering the derail makes it snag on the 48T. Anyone know a 34.9mm clamp derail (preferably xt level or so) that will work w/ a 48t top chainring & a 74 deg seatpost?
What ? Ooops i guess im in the worng area . I dont know much about cycling . But you can still give me 10 points .

Torque Technical Guide
With modern bike parts, a little technical knowledge can go a long way toward keeping them in good shape and getting the most use for your money. One of those useful concepts you should understand if you plan on installing your new bike parts or giving your ride a tune-up is torque.
Torque /tork/ n: The measure of the force applied to an object to produce rotational motion, usually measured in inch-pounds. Torque is determined by multiplying the applied force by the distance from the pivot point to the point where the force is applied.
As bolts and screws are tightened, the resistance causes bolts to twist and become distorted (they normalize once the force is removed). The measurement of this force is called torque and is measured by multiplying the applied force (pound) by the length (inch) of the fulcrum used to turn the object.
Torque in bicycles is becoming more and more important. As kids, many of us went by the theory that tighter was better, and we would stand on wrenches to make sure that the rear wheel would stay in place and keep the chain tight. Today is a different story. You probably don't ride or work on many bikes with solid steel axles and nuts with seemingly infinite torque limits. Today's bikes are carbon fiber and aluminum and titanium--softer composites that have fairly specific torque limits.
Tighten a clamp around a carbon handlebar too tightly and you run the risk of crushing the bar and stripping or breaking the soft alloy bolt. At the same time, if you are over-cautious, a loose bolt can cause just as much damage; just ask anyone who has had bars slip on a long descent or a seatpost slide into the frame in the middle of a long ride. The key is to tighten using the maximum allowable torque without damaging the bolt or any component that is affected.
How is torque determined? A quick calculation:
Let's say we need to tighten a fastener to 120 in.-lbs. We have a ratchet lever that is 1 foot (12 inches) long. We must apply 10 lbs of pressure to the end of the lever to attain the 120 in.-lbs.
10 lbs x 12 in. = 120 in.-lbs
This also demonstrates how a "cheater bar" or wrench extender aids in tightening or loosening a difficult bolt. The longer the lever, the less force needed to achieve the same level of torque. If we substitute the 1-foot lever with a 10-foot lever, how much applied force do we need to reach our 120 in.-lbs?
(X) lbs x 120 in. = 120 in.-lbs
1 x 120 = 120
Luckily, torque wrenches make these calculations for us. You adjust the setting or watch the indicator on your wrench and it tells you when you have reached your desired torque. Beam-type and digital torque wrenches can also easily tell you how tight or loose the bolt was as you are removing it (a good way to test that last mechanic that worked on the bike).
