1. Sorry, www.leafcycles.com.au (Yes, it's the Australian one, it's just what i use and it still has all the products listed on it).
2. If you took the time to look, the Leaf Block stem is the one with a 22.2mm clamp, the EvoBlock is actually a 25.4mm bar clamp size.
I checked on the website and it just says Evo 1
Are we looking at the same site? If you go to the link i posted it DOES have the Block and EvoBlock, (Products > stems). Go check the international Leaf site if you wish (just google it), Leaf make a 24.4mm stem that's 162 grams. Gosh.
Forget it man Its a beautiful stem and NOT what he wants, so it doesn't matter
