Ritchey P-650B Frame
$799.95
This is the second version of a 650b mountain bike from Ritchey – Tom started to design his first in 1977. Even back then, Tom had a feeling that there was an advantage to the "middle" wheel size, but it took the rest of the cycling world three decades to figure it out: a 650b (or 27.5") wheel provides the bump-eating smoothness of a 29er, with the light, responsive feel of 26" wheels. Finally, the era of the 650b wheel is here. The P-650b is a close relative to the P-29er. Up front there's the proprietary forged-and-machined, gram-shaving integrated head tube featured on all new Ritchey frames. Forged socket dropouts and a new chainstay-mounted rear disc brake mount save a few more grams. And like every frame Ritchey makes, geometry and tubing is carefully fine-tuned by Tom, to bring the legendary balanced, nimble Ritchey feel to 27.5-inch wheels. - Weight: 2,028g for frame (L/17”) - Ritchey forged-and-machined 1.5” tapered head tube - Clearance for up to 2.25-inch tires - Fork: Designed for use with 100mm travel forks - Headset: Integrated 1.5” tapered - Upper bearing: 41.8mm OD / IS42/28.6 (S.H.I.S.) - Lower bearing: 52mm OD / IS52/40 (S.H.I.S.) - Bottom Bracket: 68mm English threaded - Rear spacing: 10x135 - Front derailleur: 28.6 low clamp – top or dual pull - Weight: 2178g / 4.8 lbs (M/17”, frame only)

Reborn 30 years later, the Timberwolf is a hardtail incarnation of an all-mountain trail bike that can shred anything you throw at it.

The heart of the bike is Surly's 26+ platform which has clearance for 50mm-wide rims and 2.75-inch tires, so you get endless traction and the rollover-action of a 27.5-inch wheel, coupled with the snappy, go-fast responsiveness of a 26-incher. The geometry is dialed for a 140mm travel suspension fork and features a long top tube and short rear end for more of the same fun. And this thing is versatile, the frame comes with dropouts for rolling singlespeed, or geared with a quick release or a 142x12mm through-axle with a Shimano direct-mount hanger.

Surly Troll Frameset
$650.00 - $675.00
Off-road touring can be a zesty enterprise, but it’s not without its perils. Bicycles are simple machines that are extremely efficient, but all simple machines carry along with them the chance of breaking down. This efficiency can get you in trouble if your bike decides to break down far away from the comforts of your parent’s basement. If you’re going to ride your bicycles where no one can see, you better take gear that’s up to the task. Troll is up to the task. Surly's Troll was once a simple mountain bike frame with a few extras that made it nice for touring. The Troll has evolved into a frame that has been pushed deeper into the category of off-road touring. Its geometry is no longer suspension corrected, which gives it more room for a larger frame bag. The chainstay yoke has been redesigned to be fully compatible with 26+ tires and comes with the always-comfy Jones Loop bar. The dropouts still allow you to run disc brakes, fenders, a Rohloff hub, and racks simultaneously. It also comes with more braze-ons than you thought possible – there are four triple bottle mounts on the fork alone (don’t get excited, you can only run one Anything Cage per fork leg), as well as two more triple bottle mounts on the down tube. Troll is a bike that has one purpose – and that purpose is to carry you as far away from society as possible.
