Would I be right in saying the BLB Notorious are much of the same? all be it more expensive? but i would be able to get it in 47t and the branding's a nice subtle style.
Probably, I'd guess they'd all be variations of the same design as most of these companies (including BLB) don't really develop much of their own stuff. It all should be decent but IMO the second you're paying over about £80 you may as well try to find some second hand omniums.
I would assume they're the same open mould designs as the on ones and Andels that look similar and cost about the same.
They'll be pretty heavy but solid and reliable cranks, pity the logo is so ugly.
