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.

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. It has barrel bosses at the dropouts and crown, mid-blade thru-blade eyelets and triple bottle bosses on both fork legs. That's a lot of bosses. 51mm I.S. mounts use front disc spacing. - Axle-to-crown: 483mm - Offset: 47mm - Steerer: 260mm, 1-1/8-inch straight - Tire Clearance: 26 x 5.25-inch

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. For increased versatility, it has braze-ons for fenders and racks (including mid-blade!). - Axle-to-crown: 400mm - Steerer: 350mm, 1-1/8" straight - Tire Clearance: 27.5" x 2.32" or 700c x 42mm (27.5 x 1.95" or 700c x 38mm w/fenders) - Weight: 1254g

The carbon Service Course SL seatpost is specifically tuned to be more shock absorbing than the "comfort" seatposts on the market, while still passing our strict internal MTB strength test. Flex engineered into the lightweight carbon tube keeps the rider comfortable over any terrain. Better fit means better performance, and if your saddle is out of position, you'll waste energy with every pedal stroke. The secure, two-bolt clamp makes for easy micro-adjustments of saddle position, and the head has been redesigned for maximum bolt-head accessibility. The Service Course SL seatpost makes it possible for nearly any rider to achieve the perfect fit, and the clamp works with all saddle rail types. - Distinctive Zipp cosmetics - Unidirectional Carbon fiber tuned for ride comfort - Lightweight clamping system - Lifetime warranty

The perfect bike fit needs to blend slippery aerodynamics and a comfortable, stress-free body position while optimizing control over the bike. Top fitters are constantly devising new methods to maximize and balance these goals. Designed using feedback from top fitters, Zipp’s Vuka Carbon Extensions give you all the options needed to optimize your position and go for the win or your personal best: Vuka Carbon Evo extensions decrease drag by starting airflow over the body sooner while keeping the arms and wrists in a comfortable, relaxed position. The Evo shape, with a 20mm inward roll and multi-radius bend, is constructed using carbon fiber, allowing for even more complex shaping and lighter weight. - Compatible with all 22.2mm clip-on systems - Material: Unidirectional carbon - Internal cable routing - Length: 380mm

Shimano's Deore Hydraulic Brake Levers feature Servo-Wave Brake Technology for improved pad clearance, quicker pad engagement, and plenty of braking power. The lever also has reach adjustment so you can fine tune performance to suit your hands. The hinged handlebar clamp assembly make for quick and easy installation, and I-Spec compatibility eliminates bar clutter by mounting the brakes and shifters (sold separately) to the same clamp. And in true Shimano fashion, the ergonomic pivot and two-finger lever geometry mean there's power to spare and their one-way bleed system of the non-corrosive mineral oil is quick and easy.

The Airstryke II takes the features of the ever popular Airstryke and adds an expanded fit range and more comfortable armrest. The flip up bracket and classic shape are retained. Performance The Airstryke II is intended to allow riders to add aerobars to their road or adventure bike without sacrificing the ability to hold the bars close to the stem. The comfortable grip angle and smoothly curved armrest offer a relaxed position for long days in the saddle. Fit Data - Armrest Offset: -85mm to 17.5mm in 7.5mm steps - Armrest Width: 131mm to 298mm in 18.5mm steps - Armrest Stack: 40mm Origin As one of the most popular model in the history of aerobars it seemed appropriate to update the much loved Airstryke with our new generation fit range and comfort focused armrest. We didn't want to change the elements that have made the bar so successful and the changes made just enhance the adjustability and comfort. - Bracket: L2 Flip-Up - Clamp Diameter: 31.8mm (26.0 w/Shims) - Armrest: Ergo Armrest - Armrest Stack: 40mm - Reach: -85mm to 17.5mm in 7.5mm steps - Extension Adjustment: 150mm (center of basebar - end) - Armrest Width: 155mm - 203mm - Weight: 592g

The Sonic/Ergo is designed to present minimal frontal area to create as little aerodynamic drag as possible. The main purpose of an aerobar is, of course, to get the rider into a fast position. Despite a fairly minimalist appearance, the Sonic/Ergo offers a comprehensive fit range for exactly this purpose. - Armrest Offset: -70mm to -2.5mm in 7.5mm steps - Armrest Width: 124mm to 290mm in 18.5mm steps (with Extensions at 100mm) - Armrest Stack: 60mm to 70mm in 5mm increments (with aftermarket Riser Kit) - Extension length and rotation can be easily adjusted using the top bolt - Weight: 545g

Our new Sonic bracket has been designed as the successor to the J2, which has been a somewhat ignored part of our range. With this update, it brings our new generation fit range to a wider range of price points, replacing the J2 bracket. The Ergo armrest has been created to offer both a huge upgrade in fit range as well as increased rider comfort with a supportive curve to cup the arms. Performance - The Sonic/Ergo is designed to present minimal frontal area to create as little aerodynamic drag as possible. The main purpose of an aerobar is, of course, to get the rider into a fast position. Despite a fairly minimalist appearance, the Sonic/Ergo offers a comprehensive fit range for exactly this purpose. Fit Data - The extension length and rotation can be easily adjusted using the top bolt. There are 100 distinct position options achievable just by moving the armrests. Combine that with the risers and this bar offers 1500 possible configurations. As a clip-on bar it is also possible to adjust the extension width and tilt easily. This is the most adjustable clip-on bar on the market (and in history). It is worth noting that our previous top level clip-on aerobar, the J4/F35, offered 90 possible configurations. This highlights the significant step forward we’ve made with our new generation aerobars in allowing riders to precisely adjust their position. Origin - After we released the Supersonic (J5) as a premium bracket with market-leading fit options and versatility, we wanted to bring the same kind of options to the rest of our range of brackets and thus aerobars. By simplifying the extension clamp and shifting the wing forward to the bar center line, we were able to meet our targets. As a consequence of the simplification the Sonic is the lightest of our current brackets. The Ergo armrest shares the flippable design of the rest of our new generation armrests. By swapping sides or rotating the armrests smaller increments of movement are achieved – making it simple to fine tune a riders position or match the position from their previous aerobar or bike. - Bracket: Sonic - Clamp Diameter: 31.8mm (26.0 w/Shims) - Armrest: Ergo / 10mm Pads - Armrest Width: 124mm to 290mm in 18.5mm steps (with Extensions at 100mm) - Armrest Offset: -70mm to -2.5mm in 7.5mm steps - Armrest Stack: The minimum is 60mm and the bracket is compatible with our existing risers which add up to 130mm stack with (70mm of spacers added) - Weight: 559g
