Spank OOZY Trail 395+ Mountain Bike Disc Rim - Black - Red - 32 Holes, Black - Red

Spank OOZY Trail 395+ Mountain Bike Disc RimFinally, an ultra-wide alloy rim with Trail weight and true All Mountain strength! Spank Industries' Oozy Trail 395+ rims were designed to optimise the performance of both plus-size and modern "high volume" standard tyres. The Oozy Trail 395+ rim's 35mm internal width is the perfect solution for riders seeking an ultra-wide aggressive Trail rim that doesn't tip the scales. Combining Spank's proprietary Dynamal alloy, patented Oohbah profile, and Bead Bite tubeless rim hooks, The Oozy Trail 395+ offers the perfect blend of strength and stiffness with unparalleled tubeless performance. You don't have to go fat to go ultra-wide with the OOZY Trail 395+ rim.Features:Material: MGR Dynamal Alloy ERD: 27.5": 554mm; 29": 591mm ETRTO: 27.5": 584x35mm; 29": 622x35mm Hole Count: 32h Inner Width: 35mm Outer Width: 39.5mm Valve: Presta Tubeless: Tubeless ready Finish: Shotpeen anodised with laser etched logos Discipline: Trail Weight: 27.5": 560g; 29": 590g Technologies:Bead Bite (Anti Burp Technology): Running tubeless? No stress! At an incredible range of pressures, Bead Bite is the solution to keeping those tyres burp free and fixed in place. Bead Bite rim technology, paired with Spank‘s patented OohBah profile, enhances tubeless use with tyres of all types and with a greater range of air pressures.Bead Bite rims have 6 rows of tiny ridges that run along the vertical and horizontal faces of the bead seats. These tiny teeth create air seals between the rim and tyre as the bead conforms into them under air pressure. They dramatically increase frictional forces on the tyre bead, reducing the bead‘s ability to move vertically or horizontally (thus improving tyre stability and reducing burps). The bead literally becomes trapped between the vertical and horizontal ridges, even at very low air pressures. Even in tubed applications, Bead Bite rims tend to allow much lower air pressures with a reduced risk of pinch flats.OohBah (Reverse Well Design): The unique OohBah profile allows Spank to manufacture thinner walled, wider profiled, lighter rims without sacrificing strength or rigidity. Wider rims mean stiffer wheels and more tyre spread, leading to greater traction and improved comfort, and tyre performance. The “wave” shape of the OohBah inner tube adds strength and support to the vertical rim flange walls and prevents buckling. Normal straight or curved tube wells must be much thicker, and by default heavier, to offer the same support.BeadNip (Improved Tyre Fit): Another secret of Spank’s patented OohBah profile is our double BeadNip technology. The OohBah patent includes the addition of a second set of “nips” on the inner tube well, which ensures that the tyre always remains in the bead-seat, even when riding at minimal air pressures. With Spank’s OohBah patented rims, you can ride the tyres you want, at the pressure you want, on any terrain with far less fear of flats!Dynamal Alloy: Utilising the endless lifecycle of aluminion, Spank's proprietary alloy blends offer superior mechanical properties resulting in stronger rims and reduced weight through optimised design. Spank Industries has made a concerted effort to develop safe and affordable alternatives to the excessive use of carbon fibre in the bicycle manufacturing industry. Its WC DH Race Teams and most hardcore Big Mountain Freeriders are running Spank’s Dynamal Alloy rims in the choice against carbon fibre. Unlike standard recycled alloy mixes, Dynamal is a dynamically aged, highly magnesium-silicon enriched, pure alloy, which is blended with a special “secret” hardening metal. Compared to statically aged traditional alloy types, Dynamal shows a significant further increase in ultimate tensile strength and yield, without the normal reductions in fatigue life.MGR (Micro Grain Refinement Processed Alloys): Micro Grain Refinement Processes such as extrusion, forging and tube drawing can increase the strength of alloy materials by reducing the grain size. Spank uses state of the art proprietary metal forming methods, which further improve grain size, consistency and orientation, beyond that of our competitors. No other bars or rims are subjected to the number of drawing steps or level of refinement as those offered by Spank. This leads to greater ultimate strength, toughness, and ductility meaning confidence, comfort and safety.Buy Spank Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.

Spank 350 Mountain Bike Rim - Black - Red - 32 Holes, Black - Red
  • £39.99
  • RRP £84.99
  • Saving you £53

Spank 350 Mountain Bike RimThis sturdy and durable rim has been designed to tackle rough MTB (mountain bike) and Enduro trails. It features a wide profile for incredible lightweight when zipping around the corners and offers a solid, hard-wearing construction that is ready for whatever challenge you meet on the trail. Lightweight and Adaptable Tubeless Ready RimA brilliant tubeless ready rim that can cope with a variety of riding styles and under-wheel conditions, the Spank 350 Mountain Bike Rim is built to be ridden hard. Featuring a 30.5mm inner width, tyres from 2.0"-2.6" and + sized tyres can be fitted to it, making it suitable for whatever type of ride you want to undertake. Being a wider rim, it doesn't suffer from the additional weight that many larger rims have, keeping it light for ultimate speed on the descent and for making your climbs that little bit easier. The width also combines with the low sectional profile height to give radial compliance and top-notch lateral stiffness, giving you precise control and confidence as you fight to the finish line.Features:Material: Top-Performance AlloyInner Width: 30.5mmOuter Width: 35mmHole Count: 32Valve: F/V PrestaTubeless: Tubeless ReadyTechnologies: Radial Compliance, BeadBite, OohBah Inverted Inner WallWeight: 27.5": 465g (approx); 29." 495g (approx)Technologies: Bead Bite: At an incredible range of pressures, Bead Bite is the solution to keeping your tires burp free and fixed in place.
