Fox Suspension SLS MTB Rear Shock Spring (2.9" Travel)This mountain bike (MTB) rear shock spring features a Super Light Steel (SLS) construction that's lighter than titanium springs and more affordable. It's equipped with a proprietary surface treatment and stress relief process that removes residual stresses from the spring, allowing it to withstand higher stresses. Each spring is also optimised by using a smaller wire diameter and fewer coils, creating a lighter spring. Compatible with Fox DHX2 and Van RC rear shocks from 2016 onwards.All SLS springs are orange and are marked with their spring rate in lbs/in (in 25lb increments) and the maximum travel of the shock that they are designed to be paired with.Please note: This model is intended for Fox DHX2 and Van RC rear shocks from 2016 onwards. If you have a rear shock that's from before 2016, an SLS spring retainer is required (available separately).Features: Material: Super Light Steel (SLS) Use: MTB Type: Rear Shock Spring Spring Travel: 2.9" Inner Diameter: 1.385 inches (35mm)) Compatibility: Fox DHX2 and Van RC rear shocks (2016+) Size: Multiple options available to selectManufacturer's Part Number: 033-22-030 Orange 350lb 033-22-031 Orange 375lb 033-22-032 Orange 400lb 033-22-033 Orange 425lb 033-22-034 Orange 450lb 033-22-035 Orange 475lb 033-22-036 Orange 500lb 033-22-037 Orange 550lb 033-22-038 Orange 600lbBuy Fox Suspension Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
Introducing Helix, the new standard in performance footwear. Bont Cycling’s race-proven anatomic fit is now even further enhanced by a newly reimagined closure system. Experience performance and comfort without compromise like never before. Features: Durolite Strength to weight ratio's have always played an important part in Bont cycling shoe design as all materials considered and developed for products within the Bont range must comply to strict standards. Durolite has been developed and chosen for the Helix upper for its extremely durable nature and light weight. Retention System Continuous wiring spreads the load for a secure hold without localised pressure points. Cable Routing Cable routing wraps around and under the rigid carbon chassis for a wide, even anchor point. Single Boa The single Boa dial simplifies operation for quick and easy on-the-fly adjustments. Unidirectional Carbon Chassis The Helix continues with its unidirectional monocoque chassis in matt finish and is upgraded with an improved grid to assist cleat adjustment. TPU Toe Protector The toe protector not only protects the front area of the shoe from wheel rub and impact, but also houses ventilation holes for improving airflow through the shoe. Ventilation The Helix is highly ventilated with integrated air vents on the front bumper providing direct airflow into the shoe along with perforated upper and tongue to maximise breathability. Anti Stretch Between the outer leather and the liner we add a material that is proprietary to Bont to stop the cycling shoe from stretching over time. This material has similar strength characteristics to Kevlar. The material is stitched to the outer leather and bonded to the liner so it can never move or be removed, it becomes part of the cycling shoes structure. This layer assits in pedalling efficiency by maintaining a supportive structure over the top of the foot in the upward part of the pedal stroke. Last Design A last is a replica of a foot that the cycling shoe is built around. Last makers do not make cycling shoe lasts, they only make shoe lasts so perfecting a cycling shoe last requires a great deal of expertise in functional biomechanics and ongoing research. At Bont, we have been perfecting our performance footwear lasts since 1975 and the process is ongoing. We believe we place more importance and thus place more effort into our last than any other cycling shoe brand and it is the reason that Bont cycling shoes continue to be a leader in providing the most functional and correct anatomical support to cyclists than any other brand on the market. Our motto in terms of cycling shoe fit is simple, We make shoes for cycling, not walking. Carbon Fiber Bont carbon fiber is sourced exclusively from the world's #1 carbon manufacturer, Toray of Japan. The base of the Helix is made by hand utilizing uni-directional carbon fiber which is embedded with epoxy thermo setting resin. The fibers are hand laid in the matrix according to the strain they will have to bear. The Helix utilizes unidirectional carbon fiber allowing Bont to create a performance cycling shoe with very specific strength characteristics based on stress points in cycling. As unidirectional carbon absorbs less resin then cross weave fibers, it also assists in the weight reduction of the cycling shoes. Padding The Helix utilises closed cell memory foam that will not retain water assisting in maintaining a lighter shoe during wet conditions as well as ensuring sweat which can begin to break down the durability of the shoe is not absorbed. Medial Longitudinal Arch Support Structural medial longitudinal arch support is provided in all models to stop over pronation of feet. Over pronation is one of the main contributors to incorrect tracking of knees during a cyclists pedaling phase due to internal rotation of tibia and femur. This can result in knee injuries. In addition, the rotation of tibia/femur can cause the pelvis to tilt resulting in lower back strain. Anatomical Forefoot Shape Conventional cycling shoes offer a “dress shoe” type shaping. Although highly aesthetic this will cause the toes along with the metatarsals to be overly constricted, compressing the nerves between the metatarsals which often results in the common hot foot sensation. Bont cycling shoes anatomical shaping allows the foot to function in its most efficient and anatomically correct position. The foot is supported in its endeavour to relax through the metatarsal joints allowing the pedalling force to be spread across the greatest possible surface area. Anatomical Heel Cup The anatomical heel cup shaping of Bont cycling shoes provides increased stability during the pull through stage of pedaling stroke and up stroke. This stabilization is achieved without any mechanical operation or over tightening of straps/laces allowing for increased comfort and blood circulation. Lateral Forefoot Support Bont’s lateral forefoot support ensures neutral positioning of the forefoot and alleviates common issues associated with over pronation and supination. These issues often result in incorrect tracking of knees causing injuries along with hip and lower back pain.
