Meet your best riding companion for drop-bar adventures. Be it a gravel grinder road ramble bikepacking trip or fast daily commute this new addition to our Allroad family is faster smoother and 140g lighter than its predecessor the Allroad Elite.The Allroad SL’s lightweight aluminum rims feature ISM4D technology which strategically removes material from the rim where it’s not needed but keeps it around the spokes where tension is applied. Double butted spokes further reduce weight and make the wheel feel more responsive. The spokes have an aero elliptical shape that can save 5 watts of energy while maintaining your speed. Wide rims (22mm internal) are compatible with tubeless tires ranging from 28mm to 64mm for a smooth efficient ride quality.Our UST system has been improved with a new rim bed shape that makes it easier than ever to install and change tires. Fore technology attaches the spokes to the rim without the need to drill the upper rim bed so no tape is required. No hassles no added weight (another 30g saved).Our new Infinity hub platform optimizes spoke lacing with highly controlled tension for maximum power transfer and the Instant Drive 360 freewheel coupled with our automatic bearing preload adjustment (QRM Auto) provides fast engagement stiffness and added durability. The wheels use center lock brake rotors and are available with Shimano or SRAM XD-Road driver bodies and can convert to Campagnolo with an optional driver body. The front hub is a 12mm thru-axle that can convert to 15mm or quick release. The rear is a 12x142 and can also convert to quick release.

We build bearings, so we build bottom brackets. T47 is a standard we helped develop, an answer to the imprecise and often loud press fit bottom brackets that appeared on the market a few years ago. T47 offers the benefits of larger bottom bracket shells, mainly frame stiffness, with the upsides of traditional, threaded bottom brackets, precision and quietness. ThreadFit™ T47 24x fits 68mm and 73mm shell widths with 24mm spindles.It’s a silky smooth, long-lasting bottom bracket built around King’s legendary, angular-contact bearings, either steel or ceramic. These are the best bearings in the industry, and actually get faster over time, as their contact surfaces wear.You want this bottom bracket because it offers super low drag. You want this bottom bracket, because it can be opened, cleaned and repacked for years of faithful service. You want this bottom bracket, because you don’t want to think an awful lot about your bottom bracket.Key Features:King Lifetime Warranty,Legendary made-in-house bearings,Ceramic bearing upgrade available,Threaded security with PressFit 30 shell stiffness,A Fit Kit is required for use and included in the purchase price,Engineered, manufactured and assembled in Portland, Oregon USA,Uses Chris King bottom bracket cup tool for installation.
Already a legend in its time, the SRAM Red Exogram Crankset is now available with refreshed graphics to compliment SRAM RED eTap components. The SRAM Red Exogram crankset features a completely hollow construction all the way to the spider. It's hidden bolt pattern makes better use of carbon fiber to further improve stiffness and shed weight. As always for seamless, flawless performance and Yaw compatibility, the chainset has been equipped with X-GlideR chainrings. The chainrings are designed for an optimised shifting performance with the Yaw front derailleur. The stiffer rings (5mm 7075-T6 aluminum CNC-machined) feature upshift rivets with an advanced design adopted from SRAM XX. CNC machining allows for precision control of each tooth shape, ramp, and nearly every shifting feature of the chainring. Chainrings, chain, and front derailleur are designed as a single integrated system for optimised performance.Arm Material: CarbonChainring Material: AluminiumBottom Bracket: GXP (Not Included)Weight: 609g
