Recently put together a single speed winter bike and i used a jockey wheel type chain tensioner as the frame has standard qr dropouts, and on it's first outing the mech hanger broke and the chain tensioner got mangled in the rear wheel.
So i'm now in the market for a new chain tensioner but i'm not sure whether to replace like for like or get on of the roller types. Could my first choice have contributed to the mech hanger failing? The rear wheel is SS specific so there isn't alot of room for spacing out the rear cog and the last tensioner was used with the jockey wheel at almost the maximum extension of the arm (hope that makes sense!)
Bump for the new day!

I am Blaskspire stinger, Works great and looks a lot better than Mech type.
Thanks for that Dave, that may be the better option so will look into it. Only thing is i'm using a square taper BB, would that fit in behind it okay?
No I don't think it would, you need the external cups or iscg mounts. I used the Surly tensioner for a few weeks, pushing up to get more chain wrap. The thing still slipped a fair bit. Esp going up hill in mud. Seemed robust. Charlie the Bikemonger sells another similar version.
I used a Rohloff DH Tensioner with my FS bike - it's probably the most secure way of having a rear mounted one - it's basically a rear mech which is fixed so it can't move sideways.
No scope for finding a magic ratio?
If you are getting slippage, get more teeth involved.
32:16 can slip, so go 36:18 for example. Much more secure, same costs, and lasts longer.
