Hello Mark,
It's a very interesting idea but I am not sure that XNT concept can beat these two others that show less inconveniences in term of pegs choice, dropout aesthetic (and cost probably) :
1.
Taper Lock patent dropouts.
lot of informations here :
http://www.global-flat.com/smf/index.php?topic=42770.0You can still use the peg of your choice, tested by
Zion Bike, a well known company. And apparently, it's cheap.
2.
a concept by
A Bad Thing using a "snail washer" (used for longtime on trial bikes) placed between the dropout and the peg,
watch
this pic to get it
(but forget the cap concept, it could be a mess when you don't think about keeping your bike far from the ground when you fall when riding flatland with your bike : read the post here to know what I mean).
There is one thing to do on the frame dropouts : drill a little hole and tap it, then place a little screw on the hole in order to get the head of the screw as a stop for the "snail washer". I don't have a pic to clear that but I think it's understandable after watching the precedent pic.
I suppose all the
A Bad Thing frames have these two little tapered holes, actually as far as I am concerned all the ones I have watched carefully there since 2007 got these holes. For example
hereI suppose all of that is ultra cheap to make.
And that concept works good.
And I saw prototype peg that incorporated the snail, I mean the peg was machined with the snail design in it, that's interesting as well but I would prefer to use a "snail washer" to still use my old pegs.
Something else :
I feel there could be one little danger with the XNT concept : if you have the two pegs concerning by the concept, you have to be careful to rotate them in the same direction, if not you can damage maybe the axle wheel or the dropouts after tightening the wheel and riding the bike.
Let me know if I missed something please
