I had to buy a replacement after my bike blew over one weekend. The original bent really easily but I guess that's the point, it's sacrificial to prevent damage to your frame. I rang Sigma to enquire about a replacent and was expecting them to be quite expensive so was pleasantly surprised to find that they were only £10. Because they were so cheap I decided to also book the bike in to have it fitted and the gears tuned at the same time. When I collected it everything worked smoothly again and I had a gleaming clean drivetrain! Well worth the money. Sigma also gave my the old hanger back, advising it's useful as a get me home saddlebag spare in case of bigger damagee in the future. Top marks for service Sigma

I got this rear mech hanger to pop in my saddle bag just in case I have catastrophic mech failure. Very light and I feel fully prepared on my long rides. Sigma were super helpful.
