We have two 1x1 forks to offer. Our 1x1 disc fork comes with International Standard mounts and removable canti pivots. Otherwise, it's the same fork as our tried-and-true original 1x1 fork...which means you can stuff 2.7" tires between the blades and have room to spare. Both forks are built with 4130 cro-moly tubing, suspension-corrected geometry, 1-1/8" threadless steerers, and black powdercoat. 413mm axle to crown.

Rake: 45mm
Steerer: 260mm
Weight: Disc = 2.34 lbs. (1.1 kg)   Non-disc = 2.27 lbs (1.03 kg)

Our cassette-type cogs are designed to fit on standard Shimano compatible freehub bodies. These cogs have a tall tooth profile that is essential for preventing chain skip from the extra torque a singlespeed drivetrain encounters. In addition to being a stellar SS cog, the cog base width (where it contacts the freehub body) is 4.35mm, so you can stack a few of them up and use a 9-speed shifter for a simplified multi-speed drivetrain. This width also prevents it from ruining the freehub body as a result of digging grooves into it like skinny stamped cogs have a tendency to do. Surly cogs are machined from SCM415 CroMoly steel, then heat-treated for toughness and chrome-plated for surface hardening and enhanced chain lubricity. Our cogs will work with 6-9-speed 3/32" chains, although we recommend the inherently updated quality of an 8 or 9 speed chain. They are also available in every increment from 13-22t, so you can select that perfect gear.

Oh, we’ve got hubs all right. All are forged aluminum with medium height flanges, and spin on high load, well sealed, adjustable cartridge bearings over standard sized axles (9x1mm front, 10x1mm rear). This is a common size so it’s easy to find replacements should the need arise or to swap axles if, for instance, you have a QR axle and want to go solid. And did you notice we said the bearings are adjustable? This is so you can adjust play as the bearings wear so you don’t have to replace bearings as often.

Fronts are spaced 100mm to fit most forks. Rears come in 3 widths: 120, 130, and 135mm. Some are disc with singlespeed freewheel threading on the drive side, others have freewheel threading on both sides (English 1.37x24tpi), and still others have FW threads on one side and fixed gear/lockring threads on the other (1.37x24tpi and 1.29x24tpi LH respectively). Some are silver, some are black. Some have 32-holes, some 36. You get the idea. They work good, and look good. ‘Nuff said. Here are all the options:

Got a rear wheel from a geared bike collecting dust in your garage? Maybe it’s time you gave it some new life as a single-speed wheel. We now offer a single-speed spacer kit that allows you to use single-speed cassette cogs on the freehub body of your multi-speed Shimano cassette-compatible hub.

With the supplied selection of anodized aluminum spacers, you can attain a perfect chainline to compliment your road, track, or mountain crankset. Our large-diameter stainless steel cassette lockring holds everything together and perfectly matches the outside diameter of the spacers. Plus, it matches the machined shoulder of our single-speed cassette cogs (not included). The lockring is machined to utilize a common Shimano cassette lockring tool for installation and removal. This isn’t just a mix of off-the-shelf parts; we went the extra distance to give you a kit that will provide maximum functionality, durability, and aesthetic value.

Midwest single-speed legend Pete Geigle developed the 1x1 Singleator so you single-speed virgins could taste the pure mountain biking experience without spending too much cash.

Installing horizontal dropouts on your frame can be difficult and/or expensive, particularly if your steed is of the aluminum variety. The Singleator mounts right up to your derailleur hanger and provides a simple, effective, and adjustable means of tensioning the excess chain slack found in vertical dropout single-speed drivetrains.

The Singleator features a triple-sealed spring, large cog capacity, chain guides, fully-adjustable chain line, floating pulley, and a stainless steel pivot bushing. The main body is forged, so it’s strong. We’ve gone with an 11-tooth pulley for smooth, quiet operation. And, it now works with both 1/8" (BMX) and 3/32" (geared bikes) chains. Beware impostors; the Singleator is the granddaddy and outperforms all others.
