I used just the Fun Bolts on my Kona Unit, but IIRC, it had set screws through the drop out that would allow you to adjust tension before tightening down the Fun Bolts. Without something to keep the axle from sliding forward, you're going to be readjusting your chain tension more often.I have a CK hub with Fun Bolts. Will these hold up to single-speed use on a horizontal dropout? i.e. no 'tugs', just bolt clamping force holding the wheel in place
Relevance: I'm planning to replace the vertical dropouts on my Ritchey with a single-speed friendly dropout. The chainstay geometry on the Ritchey frame limits a number of the adjustable dropouts made by Paragon and others. The hooded, horizontal dropout, like what some earlier Surly and Spot frames used, would be the easiest cut-out-and-weld-in replacement.
If they back out, then they are not torqued to spec.Who's had the non-drive side back out under hard braking forces with Fun Bolts on horizontal drop-outs?
Couldn't you make the same argument for the case of the drive-side pulling forward (without set-screws)?If they back out, then they are not torqued to spec.
I have not experienced the driveside pulling forward with King Fun Bolts. Prior to that, the original Bianchi tug nuts and Surly tug nuts did not have that issue either. The tug nuts required more time and effort to set up; so I can see how there'd be some potential for user error. Regardless, I cannot personally make that argument.Couldn't you make the same argument for the case of the drive-side pulling forward (without set-screws)?
Interesting...even with the less-robust bolt set-up (compared to Chris King) it holds fine. I do notice that the bolt caps on the Surly hub are knurled, but the CK Fun Bolt caps are not (though, both hubs are knurled at the axle)...I use a Surly Ultra Fixie hub with fun bolts on horizontal dropouts and even with the torque both directions on a fixed cog it doesn't slip. When I use a QR singlespeed hub on the same frame, I have to use a chain tug.
Mod or stock?Yep, King with fun bolts holds just fine, even for trials (nearly 1:1 ratio, stamping on the pedals hard, rough landings, massive rear disc brake). Just pull the wheel back and do the bolts up tight, no need for another fixing or tensioning method.
Stock, specifically a Hydroxx. I've also had a Red Sky which was a lovely bike!Mod or stock?
I have a KOXX Red Sky stock that is dual disc. That bike tests chains and either approves em for general fleet use or denies their use!
Oh my! I remember the Hydroxx! Love my Red Sky. Wouldn't be the same without that pithy bike without a seat but with an attitude around for some playtime antics.Stock, specifically a Hydroxx. I've also had a Red Sky which was a lovely bike!
