London Fixed-gear and Single-speed

Right...I know I've seen this on here somewhere but I've searched and I can't find it. Those with Goldtech rear hubs, what chaintugs do you use? Because the axle is 12mm OD with flats on it to fit in the dropout, my DMR ones won't fit. I could drill these to fit but I'm not sure if the bolt head will have enough to bite onto then.

Thanks

Peace

mks used the wrong way round

Thanks

Surly one works as well.

I have goldtech hubs but dont use chain tugs. I find them way more hassle than they are worth
