50mm wide, and technically a single wall with internal tubes to buttress it, the Surly Rabbit Hole is designed in conjunction with the Knard 29 x 3˝ tire to provide a wide, stable footprint that walks the line between the traction and float of fat bike rims and the speed and even greater obstacle crushing approach angle of 29ers. Its weight is more than a standard 29er rim but less than a fat bike rim, so there you go. It’s made of high quality 6061-T6 aluminum with a welded seam, and comes to you round and true because that’s part of what makes strong wheels. The Rabbit Hole will also spread 2.3–2.4˝ tires, but your frame needs to have enough space. Available in the same 64 dual row spoke holes as our other Surly rims with weight-shaving cut-outs.
