Is my rear tire flat?

So, been riding my 29er Kona as ss for a while now but my chain seems to loosen too much while riding.

I have sliding dropouts but they seem to be holding tight. When this happens I loosen the quick release, pull the wheel back and resecure until it slips more again.

Could this just be a skewer quick release issue?

I do spend some time grinding up hills out of the saddle and when the chain is loose it tends to slip and fall iff creating some interesting stem to body encounters.

Thanks in advance you all!

Leave the QR loose, adjust chain tension, then set the QR. This will slide the axle forward in the dropout slots. Also, be sure the axle is all the way up in the dropouts, the axle seems to work down & out in the Kona dropouts. I have a steel 29 Explosif in the shop right now (due to kinking the non drive seatstay) and I've noticed the down & out tendency if the QR isn't tight enough.

Thanks

My sliders seem to be hanging up a bit too so I am going to take them apart and clean them up too.

Thanks for the help, I will give that a shot.

What's up with that picture? Unless my eyes are playing tricks with me, it looks like a rear derailleur on that bike.

I imagine that even though he runs gears, who would know better about sliding dropouts than SSer's?

OK. I'll cut some slack.

Even though the derailleur should take up the chain clack, to keep the axle from sliding he'll have to use some chaintugs. But it may be difficult to use them with a quick release axle. It may be easy enough to retrofit a solid nutted axle. Make sure to get the correct thread pitch for the bearing cones and get it wide enough for the rear spacing plus room for the nuts and washers. Your local bike shop can help get the right parts.

if it is the sliders then replace the bolts on the sliding drop outs.
I went from having some extra chain tensioners on there to ending up buying new bolts at Home Depot.

The Bolts were too long so I had to throw some nuts on there (only size they had)

cut the bolt short with dremel or hacksaw. much cleaner.

is it just me or would you think if you had the horizontal tension adjusting bolt tight with the locknut tight as well it shouldn't slide forward, ho snug do you keep the tensioning bolt?

i have said this before, but for some reason you don't seem to think its a good idea. use blue loctite on the bolts. they will never rattle loose again. i used the have the same problme on my old monocog. once i put a little loctite on the tensioner bolts, the never came loose again. it will look a hell of a lot cleaner than your current setup.

I was having that issue with my bike (geared) and I think I cooked the drop out. It won't stay tight regarless of how tight or what type of QR, now there is a worn out groove on the drive side.

dlbennett--If you're running gears, why don't you just slide the dropouts all the way forward and shorten the chain if necessary?

New boltage prevents it all, just need to cut them shorter, but its great for now. I would of bought the loctite but it was like 5 bucks for all those bolts, and I knew i need to get better bolts on there anyways.

I had a problem with a Spot rear single speed hub slipping all the time. I thought it was the chrome dropouts being slippery. May have been weight of the rider. May have been hardware. I bought updated hardware (stainless bolts, washers) from Spot and it seemed to solve the problem. I went ahead and got a new rear hub (Surly new disc rear hub), problem totally solved. grantheppes solved the problem with hardware but c'mon, do it with finesse. Jerry rigging a bike with those disastrous bolts - you can do better than that.

haha if you only knew that i have the piece of my steer tube sitting in my stem freely with a chris king preloader so the stem fits on. (Put the steer tube in the wrong way when I cut it) hahahaha.
