Long live long rides. Don't end yours early. Keep an extra derailleur hanger in your pack or seat bag. This one fits the Santa Cruz Superlight 3.0 and Juliana 3.0. The kit includes: one black anodized derailleur hanger and two mounting bolts.
Superlight3.0, Juliana 3.0
Actual weights are measured in-house by the Competitive Cyclist team.
Familiarity: I've used it once or twice and have initial impressions
I ordered 2 of these. At first glance everything seems fine. Santa Cruz sticker on the bag, 2 screws included and looks exactly like the hanger on my 2010 Superlight. It wasn't until I attempted to install one of these that I found the hole for the derailleur screw must have been tapped crooked. I am certain that it was not cross-threaded, but when tightened up the derailleur did not sit flush with the hanger and only contacted in 1 point on the edge. I tried the 2nd hanger (I bought 2) and it had the same problem only not quite as bad. I imagine these must have been factory 2nds because in all other ways they seem exactly like the original. I suppose they may work in a pinch to replace a completely broken hanger, but it visibly cocked my derailleur out of alignment quite a bit. I didn't even attempt to shift through the gears. I contacted Competitive Cyclist and they are sending 2 more, however they are not able to check them before they send them. I will try to remember to update this when they arrive.
Update: Competitive Cyclist sent out 2 more and a FREE return shipping label. Of the 2 new ones, one was perfect, the other was close enough. Check what you get, if it's not right, the excellent customer service will probably make it right. Still 2 or 3 starts for the hanger, but 5 stars for customer service.
