Its active foam is separated to create five comfort zones working in a smart and individual way that favours the natural movement of the pedalling phases both of pushing and pulling. This also allows it to absorb the vibrations that the base transfers to the saddle. The round shape of the M5 provides natural pelvis rotation, creating stability and support for your lumbar areas, and the distribution of the pressures on a greater surface.CPC TechnologyBenefitting from Connect Power Control (CPC) technology that's the same as used in Formula 1 racing, PROLOGO has patented it specifically for the cycling industry. This saddle uses 3D polymer cones to maximise grip when taking up an aggressive position as well as making it possible change position quickly. Offering high levels of vibration absorbing, grip and position stability, its CPC technology also reduces muscle fatigue and facilitates air flow by reducing the temperature in the contact zone.Features: Cover Material: CPC Rails Material: Tirox (Light Alloy Steel) Use: Road Dimensions: 250x140mm Rails Size: 7mm Gender: Unisex Weight: 189gTechnologies: Connect Power Control (CPC): Used in “F1” and in the military field CPC - connected Power Control is the system patented by Prologo that ensures performance and comfort providing vibration absorbing, grip and position stability. Thanks to its nano-structure, the special conical and hollow 3D polymer reduces muscle fatigue and facilitates air flow by reducing the temperature in the contact zone.

Repente Artax GLM SaddleDeveloped for the world of gravel adventure riding, this saddle features a water-based microfibre cover that provides durability and support as you explore countryside backroads. Another highlight is its carbon fibre shell and rails, which deliver an excellent combination of stiffness and strength, while keeping the weight reduced to only 160g. This means that you'll enjoy a comfortable and stable riding position, while its lightweight EVA foam padding keeps you fully supported and in control of the ride.Gravel Bike Saddle with Pressure Relief ChannelBenefitting from an anatomical rear section shape combined with a pressure relief channel that runs down its middle section, this gravel bike saddle is designed to avoid numbness and pain on uneven grounds. Another feature is the square shape of this model's front padding, which ensures improved support when pedalling in the "seat tip" sitting position.Carbon Fibre Saddle RailsThe proprietary RLS system allows the saddle cover to be easily replaced without having to change the base. By the way, the coupled double bases have turned out to offer a better absorption of the vertical vibrations transmitted by the ground. The differential section rail is made of unidirectional (UD) carbon fibre. The shell is built using long carbon fibre (LCF) technology, which makes the saddle just rigid enough and non-deformable over time.Super Lightweight EVA Foam PaddingThe padding is made of EVA, a very light material, made thicker in the most delicate support points to maximise comfort even on bumpy terrain, for those who prefer a more upright sitting position and those who often use the lower part of the handlebars. Coating: non-slip cover material, which is just as effective when wet.Please note: Make sure your seatpost clamp is suitable for 7x9mm rails. The Repente Artax GLM Saddle's carbon rails measure 7x9mm, so the seatpost clamp must accommodate this configuration. Please make sure that your bike has a seatpost clamp suitable for this measurement: the traditional 7mm clamp for round rails will not work.Features: Cover Material: Water-based Microfibre Shell Material: PA12 Long Carbon Fibre (LCF) Rails Material: Unidirectional (UD) Carbon Fibre Padding Material: Super lightweight EVA Use: Gravel Size: 275x142mm Rails Size: 7x9mm Oversize Reduces leg friction Relieves pressure from perineal area Weight: 160gManufacturer's Part Number: RP-ASXGM0-2101BK Black 275x142mmBuy Repente Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
Repente Prime 3.0 SaddleIdeal for riders who prefer going the extra distance, this versatile saddle features a hard-wearing microfibre cover that's more than capable of enduring the increased pressure from longer rides. Whether you're into road cycling or mountain bike (MTB) trail riding, Repente has also given this model a water-based coating to keep you supported in all-weather conditions.

Repente's R&D department has focussed on avoiding any hindrance to the free motion of the hip joint during the pedal downstroke, creating leverage for the cyclist in terms of comfort and thrust effectiveness. The shape, modelled on the basis of anatomical and ergonomic studies, provides the necessary support in the saddle's strategic points, for comfortable and effective pedalling.The saddle graphics, minimal and stylish, combine design with functionality. The sides of the middle-front part feature a graphic pattern in glossy paint, which has the effect of reducing any inner thigh chafing.Super-Lightweight EVA Foam PaddingThe thickness of the padding layer has been increased throughout the surface of the saddle, in consideration of the fact that the 142 mm width size is mainly used by cyclists with an above-average build. To ensure a more comfortable sitting position both on uneven ground and over long distances, EVA material, highly suitable for its top lightness and shock absorption properties, has been used for the padding. The tip of Prime 3.0 - 142 has a thicker padding layer with a square-shaped cross-section to provide the best support when moving forward along the saddle.Features: Cover Material: Water-based Microfibre Shell Material: PA12 Long Carbon Fibre (LCF) Rails Material: UD Carbon Fibre T700 Padding Material: Super lightweight EVA Foam Use: Road, Mountain Bike (MTB) Size: 275x142mm Rails Size: 7x9mm Non-slip coating Anatomical channel for Pressure relief Square front for a better support Reinforced with long Carbon Fibres Weight: 160gManufacturer's Part Number: RP-ASP3M0-2101BK Black 275x142mmBuy Repente Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

The Terra Argo's short length allows riders to sit further forward without placing undue pressure on sensitive areas. It also features an ergonomic cut-out that was developed using detailed pressure analysis and input from medical experts.Stability and ResponsivenessTo better support the Terra Argo's flexible shell, Fizik used its closed-loop Mobius rail system for increased structural stability and responsiveness.

The same goes for the dropped-nose design which allows riders to rotate their pelvis while pushing forward on the nose for better traction and power transfer.Long Distance ComfortThe padding is made from Fizik's proprietary Type-2 foam formulation, slightly thicker around the ischial sit bones area to support a more upright riding posture.
