SRAM Red Double Tap Shifters
SRAM has worked hard to make sure gear changes are instant and precise. SRAM's double tap mechanism has been further refined in the 2010 groupset to offer unprecedented smooth up and down shifts. Gear shifts are quick too due to SRAM's "zero loss" technology that means the cable is engaged instantly, meaning short lever throws for increased efficiency and no lag-time when you're waiting for the shift to come. Rather than using the brake lever for shifting up and the paddle for shifting down, SRAM’s DoubleTap paddle acts as both up and down shifter, but you need to cycle through the release click to access the next low gear. SRAM include an extra index point, past the ï¬rst gear position, which allows the paddle to be pushed beyond the release click without dropping out of gear.
If you're worried about making the transition to DoubleTap don't be, after an hour in the saddle it'll be second nature. With brake and shift levers made from carbon and housing from titanium these shifters ooze quality whilst weighing in at just 280 grams.
Comfort and Practicality
SRAM Red levers are equipped with possibly the most comfortable lever hoods we've ever rested our sweaty palms on. Size-wise, the ergonomic hoods are somewhere in-between Shimano and Campagnolo, and the levers are asymmetrical, naturally offset by 15 degrees relative to the vertical drop of the bar allowing you to easily reach the controls from any position.
Adjustability
To compliment the ergonomic design, SRAM has increased comfort further by adding "custom-tunable reach adjust" to the STI levers. You can tailor the reach to your individual preference by first adjusting the gear lever, then the brake lever. This is functionality often seen on mountain bikes, where riders need to bring the levers closer to the bar for increased control and it's a welcome addition to this road gruppo.
To set the desired reach of the shift lever, find the sping loaded adjuster cam near the pivot point of the lever, pull the shift lever towards the bar and depress the cam. Now rotate the cam to one of the 3 pre-set positions and finally unload the cam to set the lever position.
To set the brake lever reach adjustment, roll back the hood cover to expose the 3mm adjuster bolt. By turning the adjuster bolt clockwise you can adjust the reach by up to 8 degrees from the normal fully extended position. It's important to note that when the brake lever is adjusted to less than the fully extented reach position, you need to make sure that the shift lever position is adjusted to match that brake lever position. If the shift lever is set for a reach postion beyond that of the brake lever, the shift lever will hit the brake lever and not return to its neutral position causing poor mechanism performance.
Flexible Cable Routing
Cable routing isn't set in stone, there are cable routing options for if your bars have a single or double cable groove. You can choose between the front or back of the bars for the smoothest cable run, which is great if you own bars with a bend too tight to run the cables at the back, with SRAM Red you can now run them at the front.
Big Ring Trim Adjustment
Moving the front trim position to the big ring is another pro-level innovation which allows micro-adjustments of the front derailleur when using lower gears at the back. Often the big-big combo is the most efficient for powering up short climbs and being ready to blast down the other side without having to shift in the front. Big ring trim adjustment means you can run a cross-chained gear combo and trim off any friction on the fly.
SRAM Red Rear Derailleur
Those Lynx effect ads are bang on: It's all about the first impression. 90% of your judgment on the quality of a gruppo takes place in about 5 seconds; as soon as you shift gear for the very first time. It's a do-or-die proposition, you're listening for that sweet music between the shift lever and the rear derailleur, and the SRAM Red rear derailleur sings like a nightingale.
Precision
The Red rear derailleur uses Exact Actuation technology where the derailleur pulls the same exact length of cable no matter what gear you're in. It's a simple derailleur to set up, it's reliable, and it provides accurate shifting even if you're riding a bike with thicker-than-normal dropouts, a sluggish freehub, or a worn cassette.
Lightweight Construction
SRAM Red takes the sublime functionality of the Force derailleur and improves the performance through material upgrades. What you get with Red is weight loss and drag reduction. Structurally, the mech combines carbon and titanium materials and workings are supercharged with hybrid ceramic bearing pulleys, a titanium parallelogram spring and a carbon fibre inner link saving 20g.
Low Mechanical Drag
From a drag reduction standpoint, the SRAM Red derailleur pulleys are upgraded to Black Box ceramic cartridge bearings. Ceramic bearings offer invredible hardness and roundness in comparison to steel, which substantially reduces the mechanical drag of the pulleys as a whole. After aerodynamic drag, mechanical drag is the main offender in consuming the power you put into the pedals. It's why people are willing to pay nearly £150 for ceramic derailleur pulley upgrades. With SRAM Red, the upgrades come as standard.
Compatibility
The Red rear derailleur weighs 153g, and the mechanism can accommodate cassette gearing as low as a 28 tooth ring. It has ample chain wrap capacity to handle any SRAM crankset/cassette combo regardless of whether you ride a standard or a compact crankset. Owing to its use of Exact Actuation technology, it's compatible with all SRAM shift levers: Red, Force, and Rival.
SRAM Red Front Derailleur
SRAM Red's front derailleur uses a braze-on or clamp-on alloy mount. SRAM has put the focus on smooth and precise shifting, introducing SRAM Actuation to ensure the correct balance between upshifts and downshifts, which makes moving back and forth between chainrings smoother, quieter and more fluid. Shifting and trimming are fast across the range on both the traditional and the compact chainring sets.
Fine-tune Adjustability
The derailleur's compatibility with Red's left lever means fine-tune adjustability is possible ensuring smooth chain glide whatever gear you choose. You can cross-chain as much as you like and micro-adjust the derailleur for a silky ride even in a big-big combo.
Front Derailleur Specifications:
- Smooth shifting with SRAM Actuation
- Speeds: Double front chainring
- Material: Steel cage, aluminium mount
- Configurations: Braze-on 31.8mm, Clamp-on 34.9mm
- Compatibility: SRAM road shifter (Red, Force or Rival)
SRAM Red Crankset
PowerGlide Chainrings
SRAM Red's crankset blends PowerGlide chainrings and super-stiff carbon crankarms to maximise the power to speed ratio without losing power transfer through component flex. Inflexible chainrings also mean they effortlessly pick up and drop the chain which helps achieve the astounding shifting quality. As a bonus, although the chainrings look solid there's no weight penalty at all.
SRAM GXP Bottom Bracket
As standard, the crankset comes with a SRAM GXP bottom bracket upgraded with SRAM's BlackBox ceramic cartridge bearings. Much harder than steel, ceramic bearings considerably reduce the bottom bracket's mechanical drag as the carbon spindle rotates, resulting in more efficient power transfer from your legs to the wheels.
Low-Profile Carbon Crankarms
The low-profile crank arms are carbon on an aluminium spine bonded to a carbon 5-bolt spider with an integrated BB spindle. Their low-profile characteristic mean greater ankle clearance eliminating heel and ankle contact for floater pedal users.
Crankset Options
The SRAM Red crankset is available in 170mm, 172.5mm and 175mm. It comes with a GXP BlackBox bottom bracket as standard in a choice of English or Italian threads. It comes in 3 chainring combinations; 53/39, compact 50/36 and compact 50/34. The Red compact cranksets don't require a compact-specific front derailleur. You can use the same SRAM Red front derailleur for the 53/39 as the 50/34.

SRAM Red Bottom Bracket
BB30
SRAM RED & 2010 SRAM Force have a SUPERSIZED option with BB30 crank & BB technology. 30mm axle + oversized in-frame bearings = a stiffer package than 24mm spindle applications – delivering more power to the pedal at a 20% weight savings. The elegant OS crank profile gives substantially more ankle clearance eliminating heel and ankle contact for floater pedal users. Available in 130BCD Standard and 110BCD Compact crank sets.
GXP
Giga X Pipe External Bottom Bracket Bearing Assembly. While other systems rely on side loading the bearings to eliminate play, which causes premature bearing wear, the GXP system is different. The GXP system captures the left side bearing between the spindle and the left crankarm while allowing the drive-side bearing to float axially on the spindle, thereby eliminating the necessity to side-load bearings during adjustment. The simplicity of installation is refined: once it is tightened to the proper specifications you are ready to roll with a worry free BB. The GXP system uses two bicycle specific cartridge bearings and eight seals for a smooth and long lasting ride.
PressFit
A variant of the external GXP bottom bracket, PressFit cuts weight by up to 40 grams and eases installation by allowing you to press the bearing cups into the frame instead of threading them. R equires no change to the crank ?spindle length and diameter.
PressFit 30
This is a new design led by SRAM. It’s all the best from BB30 and Press-Fit bottom brackets in one captivating package. This bottom bracket is designed for 30mm spindle cranksets. The key difference with PressFit 30 is how the bearings are fitted into the frame. Bearings are housed in nylon cups which will be pressed into the frames bottom bracket shell. PressFit 30 will feature an integrated seal, pre-assembled into the cups, to further prolong bearing life. Frames will need a 46mm inner-diameter bottom bracket shell to accommodate this system. PressFit 30 for road will require a 68mm wide shell while PressFit 30 for MTB will require a 73mm wide shell. Advantages: Huge weight savings, narrow Q-factor, more ankle clearance, greater bearing durability, stiffer/stronger crank construction, simple installation. Allows for larger diameter frame tubes increasing frame stiffness. Drawbacks: Still searching
