I got some Mks tensioners, while they are handy, sometimes they are a pain in the ass when I have to do anything like removing the wheel, ect. I would just get some good tracknuts and make sure you tighten them enough.

That isnt what i was doing. Obviously the OP knows the main ****ing use of chain tensioners is to tension your chain. Thats common sense (for most people) as the name of the component implies its use. Another example would be a brake. Its for braking. Get it?
I was merely stating another important benefit for using them.
They dont require them in japanese keirin because they help the riders tension their chains faster. They require them because if a track nut comes loose during the race the rider wont throw their chain. Theyll be out of the race but they wont take the pack down with them at 45mph. Theyre a safety precaution for everyone on the track.

For riders who ride brakeless on the street theyre a common sense necessity IMO.

I'm getting new tracknuts at my LBS tomorrow. Its a easy fix to my problem. BTW Some of the responses like "don't worry about it ....your chain doesnt need to be tight" were amusing. What a ******.

kyle!

file your dropouts a little?

It's been my observation that bike equipped with chain tensioners typically have their chains set too tight.

This causes excessive binding (and thus extra friction) in the drivetrain to occur. This in turn leads to premature wear in the chain, chainring and cog.

One should be able to deflect the chain about 1/2" if the tension is correctly set.

My Waterford came with an MKS tensioner when I bought it. I promptly removed the offending part and have had no need for it since and I even run Campy steel QR skewers on my Phil Wood hubbed/Open pro clincher wheels and have had zero slippage. (I did lose a DA track nut on my tubular DA/Reflex wheels once on a front hub about 20 miles from home.)

PS I now carry extra front and rear track nuts taped to my Campy Peanut wrench in my saddle bag along with my spare tubular tire.

Sorry to dig up this old thread but I did a search and this was as close as I came up with. Does anyone know where I can find a decent tensioner (preferably MKS or NJS if possible) for the 8mm axle on my 110mm rear spaced Makino? I got a set of regular MKS allen tensioners from Ben's not thinking about the fact that they wouldn't correctly fit my axle or dropouts. The section that sits in the dropout itself is too fat and the axle hole is obviously for a standard 10mm axle. Help? Thanks guys!

finally some decent conversation.

Anyone? Paging Dr. Deathhare or other NJS specialists.. Help?
