Rated 4 out of 5 by Rover109 Fits a Surly 1X1
It worked on my Surly 1x1 frame when I wanted it to be a 1x9. My Shimano hub with disc and freehub is converted to a nutted solid 10mm axle. These chain tugs, keyed to fit 10mm wide rearward facing dropouts hold the axle securely when the tug nuts are adjusted for alignment and the axle nuts are tightened up securely. The derailleur bolted up easily to the hanger tab incorporated in the right hand tug. Don't bend or break the hanger tab when you crash or you will have to buy a new set of these tugs with hanger. That's still better than bending or breaking a tab that's permanently welded to a frame. My "new" Surly 1x9 shifts beautifully even with full length housing all the way to the Shimano Deore Shadow M592 rear mech.

Rated 2 out of 5 by Anonymous OK but old design was better
Re-built my old DMR Trailstar frame up but have lost the chain tugs, these new ones are more fidely to setup and I encroach on the chain line of the lowest cog on the cassette (9th), where as this was never a problem (but close) with the old ones!

Very well designed and very strong. Working perfectly on a dirtbike with horizontal dropout. About the size it's made for 10mm axle, dropout max distance about 2" ≈ 5cm I use it with Da Bomb RL-4 chain tensioner and it's smoothly running. Strongly recommended!

Good idea, but not as well executed.
They can fit the horizontal DOs of my '06 On-One Il Pompino, but shimming the approx. 4mm gap with a square aluminum dowel should make it even more rigid and resistant to bending from a fall or deraileur hit.
The left side chain tug (tug only side) wasn't even machined with the correct axle diameter hole to fit at all. Maybe I just got a dud, but it seems simple enough to correct with a little drilling or some time with a round file or auger.

Rated 3 out of 5 by Anonymous They fit almost any frame, they fitted to my gimp, although they had some faults, but then again.
They are not for a gimp.

Rated 4 out of 5 by Anonymous interesting
it would be helpfull if there were any sizes given ?
axle size ? // drop out size
max.distance axle // end frame
but none give
still they are excellent because of the mech hanger for a chaintensioner perhaps ?
