Chromoly hub guard, universal, did its job and keeps on going with some assistance. Not too heavy.
I cracked it, then I broke off the cracked piece and now I'm just riding it til' it says no more. May have to stretch your frame to fit. I did with both my '13 Benny Lewis Sig and my '16 ALVX v2. Not as beefy as TDGs driver side hub guard.
This hub guard has been through it. It's been on my bike since Sept. '15 and it is still going even though it broke. It broke just enough to where it was still functional, it's definitely on its last leg now. I have to constantly bend it back if I'm not smooth butter in the grind. For $25 it's ok if budgeting, but I would get TDGs hub guard instead for the extra few bucks.
