Upgrading to a set of quality tubeless wheels is the number one way to improve the ride of your XC or Gravel bike. Tubeless offers more comfort and control with less rolling resistance, and when it comes to tubeless, nothing beats the easy inflation and performance of Stan s patented Bead Socket Technology. First introduced over 15 years ago, the original Crest rim design with BST helped launch the tubeless revolution. Today s Crest S2 wheels offer quick and easy inflation, the legendary airtight seal, and a 25mm width that offers incredible stability for 40mm to 2.3 Gravel and XC tyres.25mm rim width optimised for Gravel and XC tyres up to 2.3 Patented BST low-profile rim shape for easy tubeless inflation and the most reliable seal6061 aluminium with sleeved joint and stainless steel rim eyeletsMatched wheelsets use traditional J-bend lacing and share a single spoke length for easy serviceabilityE-sync hubs offer fast 8.18° engagement with reinforced pawlsEnduro bearings with double-row freehub bearing and cromoly axle offer 47% increase in max torque capacity over Neo hubsConnection program includes 3-year E-sync hub warranty, 3-year S2 rim warranty, 1-year crash replacement, and $10 donation to trail maintenance or advocacy group of your choiceConstructed of 6061 aluminium with a reinforced spoke bed and eyeletted spoke holes for strength, the Crest S2 rim is built to last. The wheelset also features fast-engaging E-sync hubs built to handle the added weight and forces of eBikes and more aggressive riders. Thanks to cromoly axles, heat treated steel ratchet rings, double row Enduro bearings, and a pawl design that reduces stress on bearings, E-sync hubs are made to roll smoother longer. The E-sync s four pawls also provide quick 8.18° of engagement. S2 wheelsets with E-sync hubs are perfect for anyone looking for low maintenance and high performance. Like all Stan s wheels, the Crest S2 carries on a tradition of serviceability by using traditional J-bend spokes that are readily available. To make life even easier, matched Crest S2 wheelsets all use a single spoke length, and their endcaps are readily available and compatible with previous Neo hubs.The Crest S2 is an ideal replacement or upgrade for Gravel and XC bikes. Available with Shimano Micro Spline, HG, or SRAM XDR freehub, and 6-bolt or Centerlock brake style, with options to fit all popular axle configurations. Tubeless ready with rim tape installed. Whether rolling through your local trails, entering your first XC race, or setting out on a bike packing gravel adventure, the Crest S2 wheelset can improve your ride.What s included: Tubeless tape installed, requires additional valve stems.

Based on the legendary Flow rims that have won World Cup DH and Enduro World Series events, Flow S2 wheels are a great upgrade for riders looking for better tubeless performance and excellent durability. Patented Bead Socket Technology means easier tubeless inflation and more confidence on the trail. An emphasis on durability means a reinforced and eyeletted spoke bed, a quality sleeved joint, and 6061 alloy construction. A 30mm internal width makes the Flow S2 ideal for 2.3-2.6 tyres.Low-profile 30mm internal width optimises tyre shape, traction, and control for 2.3-2.6 tyres6061 aluminium with sleeved joint and stainless steel rim eyeletsPatented BST low-profile rim shape for easy tubeless inflation and the most reliable sealMatched wheelsets use traditional J-bend lacing and share a single spoke length for easy serviceabilityE-sync hubs offer fast 8.18° engagement with reinforced pawlsEnduro bearings with double-row freehub bearing and cromoly axle offer 47% increase in max torque capacity over Neo hubsConnection program includes 3-year E-sync hub warranty, 3-year S2 rim warranty, 1-year crash replacement, and $10 donation to trail maintenance or advocacy group of your choiceDurability, serviceability, and value: every E-sync hub is built around these three priorities. From cromoly steel axles and double row Enduro bearings, to special heat treated steel ratchet rings and a pawl design that reduces stress on freehub and bearings, every detail of the E-sync hub is designed for durability. E-sync hubs are also designed for fast engagement, with four pawls needing only 8.18° of rotation to engage simultaneously and put power to the ground. E-sync hubs are perfect for eBikes and riders who demand stronger components, but still want the fast engagement of a high-performance hub.The Flow S2 wheelset is available with Shimano Micro Spline, HG, or SRAM XDR freehub, and 6-bolt or Centerlock brake style, with options to fit all popular axle configurations. Tubeless ready with rim tape comes pre-installed. S2 wheels are built to last long, but also be easy to service and update with changing axle and cassette standards. Traditional J-bend spokes and lacing have a proven history of ride quality, durability, and serviceability, and matched S2 wheelsets all use a single spoke length, making it even easier to own and service your S2 wheelset for years.

Shimano Tiagra 4725 2x10 Speed Road Disc BrakeThis tough disc brake offers you fantastic entry-level braking performance with the help of Shimano's top-tier technologies. Its lever gives you smooth and effortless operation thanks to its redesigned internal shifting unit. Simple to set up and maintain, its caliper gives you the excellent ergonomics and technologies found on Shimano's top-of-the-range Dura-Ace series at an affordable price. Features: Use: Road Speed: 2x10 speed Mount: Flat mount Piston: 2-piston Oil: Mineral oil Reach Adjust: Tooled Clamp Band Inner Diameter: 23.8-24.2mm Type: Dual Control Lever Technologies:Shimano Index System: Every Shimano equipped multi-gear bicycle includes Shimano S.I.S - Shimano Indexed Shifting. It's the technology behind that "click" you hear and feel every time you shift through your gears. That "click" captures the light, precise, and consistent shifting bikes equipped with Shimano deliver. It's the sound of perfect gear changes, of levers directing derailleurs in harmony and the feeling that resonates into your hand, letting you know that your commands are being answered.Reach Adjust: Its brake lever is equipped with a reach adjust mechanism. The distance from handlebar grip to lever can be adjusted to suit any hand size, type of riding and individual rider preferences. Ice Technologies: The fade, which can occur to disc brake rotor and pad when braking on a long downhill ride has a negative impact on the braking performance. Shimano has adopted Ice Technologies disc brake rotor's and Ice Technologies pad's to realise the cooling technology for consistent performance. The clad disc brake rotor blade, which has a 3 layer-sandwich structure of stainless steel, aluminium and stainless steel, provides better radiation performance achieving from 400˚C to 300˚C surface temperature. Also, the radiation fin has been adopted for the pad. Moreover, the clad disc brake rotor blade and the radiator fin provide long pad life, less noise, less fade and lightweight. One Way Bleeding: One Way Bleeding was developed for quick and easy prevention of air in our hydraulic system. We have streamlined the oil route throughout the system to prevent air bubbles from being captured in the system. One way oil routing plus a funnel tool with mineral oil provides an easy and clean bleeding system.Click HERE to check out the Shimano Brake Reference Guides.A 2-year warranty is offered with all Shimano products from Chain Reaction Cycles (3 years on Dura-Ace and XTR products).Buy Shimano Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
