I was thinking about getting the MKS chain tensioners, but I'm confused about the differrent models available. Universalcycles has them for $16, but it's the 10 mm version that uses an allen key and fits 3/8 inch axles. Benscycle has two versions, an aluminum frame one (fits up to 9 mm) or regualr (fits up to 5 mm) and both use a 10 mm wrench (or your fingers) they're both $30, and neither mentions anything about axles.

I'm not sure which one I need. The bike I'm putting them on is a cro-moly Mercier Kilo TT. I'd think that the version without the allen key would be easier, but if it's impossible to turn with my fingers, an allen key version would be better. If anyone is using these chain tugs and has any input, it would be greatly appreciated.

You'll be fine with the regular version... it depends on the width of the track end itself. Also be careful that you have enough room, they prefer ends that are on the longer side. My Bare Knuckle has average length ends and after installing them there just wasn't enough room to really have much adjustment.

I have the normal one from Ben's. The difference between the two is the thickness of the track end. I had to scrape the paint off of mine in order to get it on. Ben did not have the 9mm at the time. My track bike is a steel Bianchi Reparto Corse.

I know nothing about the one at Uni-cycles. It looks as if it might not have the telescoping adjustment.

Recommend measuring the thickness of your track ends and getting the one from Ben's that fits. Ben's also sells them on eBay.
