spot on said:By the way, is there any rear wheel slippage using those hand tightened wingnuts? Do you use a chaintug as well?
Fortunately (!?!), it occurred to me before taking the bike on the road that the significantly OLDer nuts with FLAT faces probably weren't going to hold ... so, for the time being, with the serrated/knurled/whatever faced nuts (common on MOST modern hubs) it hasn't slipped ... yet!!
Maybe, I'm not pedaling hard enough ...
I think that (as long as the 'outer face' of the nuts that lock the cones in place are knurled) you simply need to be sure your dropouts are as close to parallel to the center plane of the bike as possible so that there is maximum surface contact.
I certainly hope that if/when the wheel slips (!) that I won't be grinding uphill. If I ever determine that slippage is because I can't tighten the wingnuts enough (I think it IS as tight as a skewer tightened wheel, but perhaps not), I'll probably "cut" some radial "gooves" in the washer that faces the outside of the dropout ... and, hope that provides enough additional "grip" for the wheels OR I'll just switch to "standard" nuts.
Remember, I'm just using a BMX Freewheel ... but, maybe I should consider carrying some "regular" nuts + a wrench just-in-case!
BTW. For some reason, I do have some MONKEY NUTS dropout "spacers" ... but, they really wouldn't do too much on the forward facing dropouts ... like the adjustable chaintug, I think there may be a benefit with rear facing TRACK dropouts ...
