PROLOGO Dimension Tirox 143 Saddle - Brown Stone - 245 x 143mm}, Brown Stone
  • £83.99
  • RRP £119.99
  • Saving you £30

PROLOGO Dimension Tirox 143 SaddlePROLOGO designed its Dimension Tirox 143 Saddle to offer the ideal balance of comfort, performance and lightness. Shorter and wider than the “traditional” racing saddle design, it has a nose that is 3-3.5cm shorter to reduce frontal pressure when the rider is in their most aero position (ie. riding on the drops).Supportive Saddle With Pressure ReliefWith its width of 143mm, central cut-out and full-length pressure relief channel, the Dimension Nack 143 helps to distribute the rider's weight across the saddle. This eliminates compression of soft tissues and tendons to prevent numbness and discomfort in the perineum area. These features make it ideal for those with wider sit bone measurements and those who encounter central discomfort on longer rides.Features:  Cover: Microfibre with "CPC" technology  Padding: Light Foam  Rail: Tirox 7x7mm  Size: 245x143mm (LxW)  Semi-round shape  Wide anatomical "PAS" channelTechnologies:  CPC - How does it work?      Shock Absorption for a cushioning effect. Thanks to the strategically placed volcano shaped polymers, the elasticity absorbs all shocks and vibrations resulting from sudden impacts and poor road surfaces        The CPC Polymer - The CPC is a special 3D Polymer by the long chain molecular aggregation. It differs from all other polymers present on the market as it has the ability to absorb shock and vibration, and it will not lose its main features over time, ensuring its effectiveness in any weather conditions for a long time        Vibration Absorption - The CPC with its Nano-structures, protects muscles, tendons and soft tissue stress, shock, vibration and oscillation that results from continuous pedalling, this reduces muscle fatigue, improving recovery time after riding        Grip and position - The CPC ensures perfect grip and positioning. The design of the material CPC (multiple empty cylinders), creates a "vacuum effect", ensuring a perfect posture and better aerodynamics. There are many advantages for the athlete including increased power while improving performance and comfort        Air Cooling - The CPC allows a continuous flow of air, improving comfort and performance in all weather conditions        Massaging and Manipulation - Thanks to this special material, CPC system uses the kinetic power produced by the athlete to stimulate blood flow and eliminate tingling or numbness. This benefits the nerves and tendons by helping to avoid tunnel carpal syndromePAS TechnologyPAS technology, perineal area system, is studied with a saddle central tunnel in order to eliminate pressure spikes and numbness in the pelvic and prostatic area. PAS ensures maximum blood flow to the genital and perineal area of a man and woman's body.Pas system scientifically eliminates the contact between the saddle and the genital's area, improving comfort and ensuring at the same time the general well-being.PAS is produced with premium materials which offer modular base stiffness and long-term durability.Buy  PROLOGO Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

Park Tool CRS1 - Crown Race Setting System
  • £80.99
  • RRP £89.99
  • Saving you £10

The Park Tool CRS1 Crown Race Setting System has taken a fresh new approach to crown race installation. Traditionally, a mechanic would slam a tube down onto the bearing surface to set the race in place. The CRS1 offers a different approach that offers faster, safer, and more precise installation. The bearing surface is spared a direct hit by using different inserts to ensure proper fit on the race. Choose the correct insert then slide the tube over the fork tube and into the top end of the insert. Using a hammer, tap firmly on the end cap of the tube and seat the race into its proper place safely and accurately. The CRS1 set includes one universal setting tube, three 1 inserts, and three 1-1/8 inserts.

Rotor QX1 Narrow Wide Oval MTB Chain Ring - Black - 4-Bolt, Black
  • £80.49

Rotor QX1 Narrow Wide Oval MTB Chain Ring For ultimate in single ring performance, throw the new Rotor QX1 oval mountain ring on your REX 1 cranks. You’ll be using the same chainring set up that led Christoph Sauser to victory at the Cross Country Marathon World Championships.Read the interview with Cedric Gracia on Oval Chainrings here.Ovalized chainrings for maximum performance Introducing the new QX1 chainring, already XCM world champion under Christoph Sauser. The QX1 has an alternating wide/narrow tooth profile which prevents the chain from dropping in the worst conditions even without a chain guide. Installation does not require disassembling the crankset from the bike, making ideal gear selection easier.Why Q-Rings? Q-Rings boost your performance by varying drivetrain resistance during pedaling in line with your legs natural strengths and weakness. They make better use of the strongest muscle groups (increasing positive work) and compensate for the weaker zones in the pedaling stroke (reducing negative work).PERFECT SPINQ-Rings make better use of your strongest muscles The muscles recruited during pedalling, their relative strength during pedalling and the torque produced as a crankset rotates are shown in the figures below. From these graphs, it is clear that a round chainrings’ constant level of resistance interferes with optimal pedalling dynamics. A Q-Ring gives a silky-smooth “perfect spin” by smoothening out torque variations and making better use of your strongest muscles.RIDE FASTERPeer reviewed scientific studies Peer-reviewed scientific research has shown that Q-Rings offer a clear increase in performance compared to round chainrings. Elite level cyclists saw a 1.6 sec advantage in a 1KM TT study, generating 27W more power. For comparison, 60mm aero wheels often claim 1.5-1.8 sec/km and 16W savings. What does this mean when you’re riding? You will discover increased endurance, realize explosive sprints and see a newfound tenacity in climbs. You will find that you can stick with the hardcore group that usually drops you. You will become an improved version of yourself, ready to set new PR’s and discover a new depth of performance. Triathletes will notice reduced strain in the bike split and better run split performance.RESEARCH OUTCOMEIncreased speed, reduced consumptionQ-Ring sprints were faster (-1.6 sec & 0.7 kph-1.8%) and generated more power (+26.7W-6.2%)Reduced oxygen consumption and heart rate.Q-RINGS INCREASE PERFORMANCEYour effort has its payoffImmediate performance increase on switching from round rings to Q-Rings. And vice-versa.It also appears that the more effort a cyclist exerts, the greater the benefit of Q’s.PEDALLING SMOOTHNESSQ-Ring-Round Ring Comparison Far from feeling unusual, a Q-Ring feels much rounder than a round ring. A SpinScan analysis visualize a cyclists power delivery, with a bar graph indicating the variation from maximum to minimum output and a polar graph showing the rotating shape of the power profile. By comparing the left hand Round chainring SpinScan and the right hand Q-Ring SpinScan below, one can see that Q-Ring graphs are clearly smoother (less variation in torque in the bar graph) and fuller (less of a peanut shape at the weakest point). OPTIMIZED PEDALLINGSpinScan When one projects a polar plot of a typical SpinScan over the varying drivetrain resistance of a 53t Q-Ring during its rotation, the value of a Q-Ring is clearly visible: Maximum power is met with a “56.5t” Time trial sized chainring diameter and minimum power is met with a “50.4” compact size chainring diameter. This variation creates the “perfect spin” we all aspire to, that simply isn’t possible with round chainrings. This is because Q-Rings compensate for the weakest zone of the pedalling stroke and maximize use of the most powerful zone.OCPOptimum Chainring Position You can micro adjust the position of your Q rings to suit your riding style. Q-Rings use your leg muscles at a different rate than round rings, thereby changing your intramuscular coordination of motor units. Thanks to the OCP (Optimum Chainring Position) of the Q-Ring, you will find your best position seeking both comfort and efficiency. A standard crank in combination with the OCP of the Q-Rings, allows approximately 5 degrees of adjustment.Pedal comfortably in all cycling positions The OCP (Optimum Chainring Position) of the Q-Ring allows you to pedal comfortably in all cycling positions:SittingStandingClimbingSprintingELITE ATHLETES CHOSE TO RIDE Q-RINGSAs a personal choice Professionally, athletes who have chosen to ride Q-Rings have put to rest any doubts about their performance by winning two grand tours, more than 25 Ironman races and over 20 UCI elite Road, MTB and CX world champion titles. Features:The QX1 has an ovality of 12.5% to help the you accelerate better, feel less muscle fatigue and experience smoother torque and better grip off road.The alternating thick/thin tooth profile keeps your chain from dropping in even the worst conditions, eliminating the need for a chain guide.It is compatible with Rotor Rex 1.1 and Rex 2.1, SRAM XX1 and Specialized cranks thanks to crank specific spiders from Rotor. BCD: 76mmPlease note: QX1 rings have a unique BCD and will need adaptor spiders (not included) to fit Specialized or SRAM single cranksRotor chainrings & road cranks compatibility chart (.PDF) - Here you will find the specific Rotor chainring designed to work with your crank.Buy Rotor Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
