I'll try to keep this short and simple. Setup: LGM pads in heatsink backings 05 maggy water bled 08 echo lever with chorillas TPA echo tr brake clamp 07 echo rim light sharp grind (I think it's 07...) Two little problems. Firstly, heatsink backings combined with these LGM pads and standard brake clamps there were too thick to fit inbetween my rim and the cylinders, TPA all the way out and the pads were still touching the rim making it unridable. I had to sand off about 1mm of material before there was enough room to clear my rim. People with tensile offset mounts won't have this problem. Won't be a problem either if you are using TNN or the new phatpad backings. Secondly, the 2 bits that stick out on the pads (the bits that fit into the backings) was too wide to fit in the heatsink backings. I had to cut off about 1mm in total on both sides before it would fit into the backings. So what are they like?! FREAKING AWESOME! They certainly hold just like the CRMs and I do dare to say LGMs are even better! Just like Le@Tnn says, these have raw power with excellent bite and holding power. They just hold on everything I do, ok they did slip but I have an odd grind, pads don't hold as well if my wheel spins backwards. Pedal hops, wheel swaps, gaps or even just jumping around on the back wheel these pads hold! Also, these are the best bads I've used in the wet as well. It wasn't raining yesterday and today so to simulate the rain I poured water on my pads and rim. As most people know, when pads are wet they significantly loose that bite and hold but the difference in these LGM pads from dry to wet is much much less then you would imagine. The bite and hold is still there and I was actually comfortable riding them when wet, the honk noise is still there if you are bothered by sound of pads. I've used phat pads and coust pads in heatsink backings, rock blue pads, old CRMs and boxx browns in power backings and to be honest none of them held better than these LGMs when wet. You really need to try these out for yourself to understand just how good these are. I would actually say these are serious competition to phatpads as well! I'm coming to the Reading ride too, so if you want a try feel free to ask me! I'm on a silver czar mod, and I'll probably be the only chinese there so you shouldn't be able to not see me Here's a few pics of the pads and the packaging they come in, I hope Le doesn't mind me posting them up!
