We started making headsets in 1976 and have been refining them ever since. Our DropSet™ 4 is built to be precise and dependable and sets the standard for quality integrated headset function delivering precision performance that is built on the same pedigree of Chris King headsets from the past 40 years. - Engineered, manufactured and assembled in Portland, Oregon USA - King Lifetime Warranty - Legendary made-in-house bearings - Patented GripLock® retention design for dependable headset adjustment (US Patent 8662517) - 42mm 45x45 upper and lower bearing - Compatible with our included baseplate and 45 degree integrated crown races

Why We Make This The simple answer is that many contemporary bicycle frame designs call for the headset bearings to ride inside the frame's headtube. After decades of making press-in bearing headsets, we needed to make headsets that worked in these newer frames. From the beginning we understood that integrated headsets posed a unique challenge in that the bearings are not pressed into a cup and sit loosely in the frame. When bearings are not pressed securely into a cup they shift and move, rapidly losing preload. As preload drops, the bearings are more susceptible to creaking, damage, and failure. That's a problem we know how to solve. Why You Want It Enter, our patented GripLock™ bearing cap. The GripLock™ preloads the headset independently of clamping onto the steerer, so it retains preload far better than the competition and is impervious to the ill effects of load spikes from large hits and heavy braking. This means smoother steering, no more creaking, and a longer lasting headset. Our GripLock™ design also takes the guesswork out of preloading a headset, because the bearing preload force is independent of the clamping force. Our headsets can be preloaded to a torque spec. Compatible with many Specialized mountain bike frames, see headtube specifications here. Not compatible with the 21'-22' Stumpjumper EVO. - Engineered, manufactured and assembled in Portland, Oregon USA - King Lifetime Warranty - Legendary made-in-house bearings - Patented GripLock® retention design for dependable headset adjustment (US Patent 8662517) - 42mm 45x45 upper bearing for 6.85-7.05mm bearing ream depth. - 52mm 45x45 lower bearing - Compatible with our included baseplate and 45 degree integrated crown races

Like its QR cousin, the Disc Trucker Thru-Axle Fork is designed to mount racks and fenders and haul your worldly possessions. It's also got modern touches like dynamo routing, compatibility with flat-mount disc brakes, and three-pack mounts on both fork blades to satisfy your deepest cargo desires. Captured 12mm thru-axles make tool-free removal and installation possible. Offered in 26" and 700c wheel sizes, the Thru-Axle fork clears 26 x 2.1" or 700c x 47mm tires. With a 1-1/8" steerer, it's powder-coated and constructed using the same Chromoly steel as all our other frames and forks. Why? Because we swore a blood oath to steel and we intend to keep it. Note: The Disc Trucker TA Fork is designed to pair best with second-generation Disc Trucker models—those first released in 2020. Defy this guidance at your own peril. 26 Inch - Axle-to-crown: 376mm - Offset: 45mm - Steerer: 42–54cm frames = 300mm, 1-1/8" straight - 56–62cm frames = 400mm, 1-1/8" straight - Tire Clearance: 26 x 2.1" (with or without fenders) 700c - Axle-to-crown: 390mm - Offset: 45mm - Steerer: 56–64cm frames = 350mm, 1-1/8" straight - Tire Clearance: 700c x 47mm (with or without fenders)

The Ice Cream Truck fork is made from 4130 CroMoly steel and is designed for Surly's Ice Cream Truck frame. It's ready for trail use and features butted and tapered blades with thru-axle dropouts spaced at 150mm.

This beauty here was designed alongside Surly's Midnight Special frame. In an effort to shed a few grams (it's for a road bike after all), they opted to utilize a unicrown design rather than a lugged one. In addition to the weight savings, it also looks really nice — don't you think? Like the Midnight Special frame, this fork is equipped with modern road standards like flat mount disc brakes and a 12 x 100mm thru-axle. For increased versatility, it has braze-ons for fenders and racks (including mid-blade!). - 100% CroMoly construction, fully brazed crown - Mid-blade thru-blade eyelets - Rack and fender eyelets at the dropout - 12 x 100mm thru-axle - Clearance for 27.5 x 2.32 or 700c x 42mm tires

In addition to the weight savings, it also looks really nice—don't you think? Now, we don't throw the phrase "future-proof" around lightly, so we won't use it here either. What we will say is that, like the Midnight Special Frame, this fork is equipped with modern road standards like flat mount disc brakes and a 100mm x 12mm thru-axle.

Three decades ago, SRAM was founded on a product called Grip Shift and an idea that shifting a bike should be easier, better and more intuitive. It’s more advanced than the original, but the XX1 Eagle Grip Shift follows in the same tradition of making shifting easier, better and more intuitive. The XX1 Eagle Grip Shift system includes robust internals that make it more durable and its shifting performance more precise. But just like the original, it is total control in the palm of your hand.

SRAM's 11-speed XX1 Grip Shift fires off shifts quickly, precisely, and most importantly, dependably. It uses SRAM's X-Actuation for sharp, consistent shifts over any terrain, in any condition. Its Rolling Thunder ball bearings have zero friction or play, letting you shift with very little effort. A carbon cover keeps the weight down, something all riders can agree on. The included locking grips offer a secure hold on your bars and makes a neat single unit. Just in case you don't like the grips, the shifter also plays well with other grips.

SRAM's S300 1.1 single-speed Crankset combines their stiff 7075-aluminum chainring with their lightweight 6061-aluminum forged arms. The high-profile teeth are compatible with 9- and 10-speed chains, and the stout spindle efficiently transfers your power. Plus, GXP bottom bracket cups are included.
