I agree with Jason on this one, except that there are twist and lock poles out there that actually do work and last a long time. They are called $250 poles. But honestly, if you are going to spend the money, get the FlickLock.

In that case, you may have just bought a pair of poles that can't do what you expect them to, which is to stay tight for an entire hike. The twist and lock poles are kind of an outdated technology as far as poles are concerned. The threads inside the locking mechanism are just asking to get worn out or stripped every time you make an adjustment. It's a catch 22. If you don't tighten the poles tight enough, they don't stay at the height they are supposed to. If you tighten the poles too tight, every time you do the threads will become less effective. I would recommend finding a pair of poles that have the FlickLock system. You simply pull a lever out from the pole to adjust, and then clamp it back down to tighten, much like the quick-release lever on bicycle tires and seats.

They twist and lock to tighten at two different points on the telescope.

I can't really tell with the picture, so you'll have to tell me if the pole extensions have a twist and lock or a lever clamp.

I am having trouble with my Longirod Trek hiking poles. I tighten the extension locks as tight as I can, but they still loosen up after only an hour of use. Is there a trick to this that I need to know about? Is this a defect that is covered by my warranty?

The M2121 pedals take a standard MTB cleat. Fortunately, you don't even have to worry about any of that. The pedals are actually packaged with the cleats! All you need to do is buy these pedals and then some MTB compatible shoes. Sometimes, the shoes will come with the cleats as well, depending on the brand. This is handy because you will wear the cleats out. I have the M2121 and this is a picture of my setup.

I would be interested in buying the M2121 pedals, but I need to know what type of cleats they pair with first. Any help?
