For me there is nothing worse that grinding big ugly steel pegs when canyon carving the twisties. The sound is akin to having your teeth worked on at the dentist.
If you suffer from the same pet peeve and think your pegs are lame, heavy, and have no ground clearance then do yourself a favor and check out these pegs from Thrashin' Supply Company. These pegs are made from CNC-cut aluminum right here in the USA. They have beefy steel adjustable shafts and are even shaped for maximum cornering. To top it all off, the folks at Thrashin' Supply Co. also have a sweet matching toe shifter lever to complete the awesome ensemble.
