None of the current Scott models (2010 on) have integrated dh's. They were there to assure alignment/stiffness in the original CR1 design that came out in maybe 2004?

I bent the dh on my '06 CR1 SL (RIP...). My chain opened on one side of the connecting link, and it wrapped the rd, and dh around the hub. After checking with Calfee, I decided to buy the Addict R3 under Scott's crash replacement policy. Calfee works with Scott to obtain the replacement hanger. After killing one frame, I just didn't want to risk it a second time.

Prior to that, I'd bent the hanger slightly during routine transit in my car, and the bike shop was able to straighten it out. I've had to replace dh's on my mtn. bike after just getting a stick caught in the chain, so it's really quite easy to bend one beyond repair.

Also, when I did the frame replacement with Scott, they had the local dealer cut out the bottom bracket portion of the frame to assure it wouldn't be used again. I took the remains of the frame, and did a "destructive test" of what was left. The frame broke up like paper mache. It was most unsettling. The layup of the new Scotts is totally different and seems to be much more robust. I really love my Addict. But I really loved my CR1 SL while I was riding it too.

If you have an older Scott with an integrated dh, get a sacrificial bolt to attach the rd to the hanger. The bolt MAY break off before the hanger bends beyond repair.

Once again, this is not an issue with new Scotts, and was never an issue with the Addict (to the best of my knowledge).
