Renthal Integra II Direct Mount MTB StemThe new Integra II Direct Mount stems feature the same lightweight, 6-bolt design as the original Integra and Renthal have improved the structure of the stem. The Integra II uses the same C-shape clamping system as the Apex stem range, which has been increased in size to cope with the demands of top level DH racing.The size range has also now increased to include 45mm and 50mm lengths. Both of which are available in either zero rise or +10mm rise giving you four options.Buy Renthal Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
Renthal Integra 35 Direct Mount MTB StemRenthal's challenge with the Integra stem was to keep the strength, stiffness and durability of the larger 35mm diameter package at the same weight as the 31.8mm equivalent. The strength, stiffness and durability were all matched to the 31.8mm equivalent, with an average of just 1.5g added to the Integra.The new Integra 35 Direct Mount stems feature the same lightweight, 6-bolt design as the original Integra II and Renthal have improved the structure of the stem.The Integra 35 uses the same C-shape clamping system as the Apex stem range, which has been increased in size to cope with the demands of top level DH racing. The use of two independent, C-shape handlebar clamps allows the stem body material to be reduced to a minimum, whilst maintaining an incredibly stiff and strong structure.The ultra-wide, 64mm handlebar clamping area increases torsional rigidity and the use of just six bolts vastly reduces overall weight. In addition, the uninterrupted clamp on the underside of the handlebar eliminates stress risers found on most other clamps, which can lead to handlebar failure.Features: Material: CNC machined 2014 aluminium body and 7075 aluminium clamps Clamp Diameter: 35mm Weight: 157g (50mm x 0mm)Buy Renthal Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

The S-Works Venge stem has been designed to work as a system with the Venge cockpit to optimize aerodynamics stiffness and weight. Seamless integration with the 2019 Venge frame and hidden cables. Optimized for use with the S-Works Aerofly II handlebars for integration. Its dropped clamp and flat upper profile cheat the wind for the maximum aero advantage. Extremely stiff for responsive handling and out of the saddle sprinting. Approximate weight: 207g (100mm). 80-140mm length options.
The Aeria Ultimate stem has been designed to complement our Aeria Ultimate Bar and Carbon 1/Twenty Road barIt offers hidden cable routing and the ability to hide a Di2 junction box or EPS Interface (100 mm version)The low rise options allow a rider to get into a low, aerodynamic position – especially useful if you need to compensate for a modern, high stack frameMade of forged 6061-T6-ALStack: 12 mmWeight: from 380 g for 70 mm version.
A carbon fibre body and aluminium faceplate provide a superb interface with your handlebars and help reduce hand and upper body fatigue on rough roads, while the carbon construction is torsionally and laterally stiff so it's ultra-efficient as you’re zipping into corners or sprinting for the line. The faceplate is cold-forged aluminum, which provides a highly reliable and strong grip on the handlebar, enhancing your steering. At just 130g for a 120mm stem, the Primavera will shave precious grams from your race ready machine, rivaling many stems at a much higher price point.
Prime Primavera Carbon Road StemThis top-quality stem is specifically designed for road use as it offers great stability, low-weight and confidence inspiring control.
