The least expensive way to ditch 40+ grams of rotating weight is with our Turbo Talc Tubes. A patented, oversized 4.8cm valve base prevents tearing, while a partially threaded valve stem provides a clean interface with pumps. Our lightest and most supple tube offering, it's also been proven in rolling-resistance testing to reduce drag by as much as 13% per wheel.

Makes switching chainrings very easy… although you do need a specific tool for the job.
The new price for a replacement for my gen2 is silly. This one is better price and works, you just have to swap the bash guard and bumper at top. This is a better price and I also got a sale discount. much more reasonable. Thanks!
I'm glad I bought these guards. They do what they're made for: No more bruised or bloody ankles from smacking rocks or cranks. I do have to say, however, that the photo seems a little misleading to me. I thought these would have a smooth finish like other G-Form products, based on the photo. Instead, they are fabric, so only time will tell on durability.
