Hey

As for dropouts, thanks for correcting me, they are quite similar to those from picture but bit more pointing downwards so I called them vertical but they are indeed of semi-horizontal type.

The bike is singlespeed on rather high gearing and I had issues with wheel being pulled in past(like when aggressively accelerating from standstill or riding uphill), but it could be due to poor quality QR skewers. Now I am using proper steel ones and they seem to hold better. I said I used tensioner(made for track dropouts), just not to tension chain but to ease and speed up wheel alignment process. The chain is being held by QR skewer(my process is to align wheel first using tensioner, then lock skewer and then loosen tensioner - so everything holds up just on QR force).

Anyway, I was just wondering are there any tugnut tensioners for frames with semi-horizontal dropouts because I've never seen ones.
