How tight do I need to tighten the M10 bolts to keep the wheel tight in my frame?
You need to follow our torque specification of 40Nm or 30ft/lbs. If you still have trouble keeping your wheel in the frame, do not overtighten the bolts. Take your bike into your local shop so they can help diagnose your problem. You should use a torque wrench to ensure your bolts are tightened to spec.

What's the difference between the Chub Single Rear and the Chub DirtJumper?
Two things. The Chub Single Rear has an aluminum axle while the Dirtjumper has a heat treated steel axle for increased impact strength. The other difference is the Single Rear uses Titanium M10 bolts and the Dirtjumper is spec'ed with Stainless Steel bolts.

I've converted my vertical dropout frame with a derailleur hanger to a singlespeed frame and I want to use a QR instead of the M10 bolts. Will this work?
At the moment, no. You'll need some machined adapters to thread into the axle that will mimic a standard QR endcap/axle assembly. If we get enough requests for these, we'll make them. Drop us a line.

Do I really need to use anti-seize on the M10 Titanium bolts on my Chub Single Rear? Should I grease the M10 stainless bolts on the the Chub DJ Rear?
Yes. If you fail to use anti-seize, commonly called Ti-Prep™, you risk the bolts seizing in the axle. Repair will be a time consuming and expensive endeavor. For the stainless M10 bolts on the DJ, apply grease to the bolt threads before tightening your Chub.
