The super SLR dual pivot design of the Shimano R451 road bike brake keeps operating friction to a minimum, improving braking performance. The 57mm drop is measured from the central mounting bolt to a virtual point between the pads, which aligns with the centre of the pad at its lowest point.

Just a light touch, as soft as a mouse click, is sufficient for the front or rear dérailleur to instantaneously select the correct gear.
The Shimano Dura Ace BB-R9100 bottom bracket features smaller lightweight bearings and an advanced seal construction for smoother rotation and increased durability. It is designed to work in combination with the Dura-Ace R9100 crankset to offer optimal stiffness and a smoother pedal stroke.
The clad steel/alloy/steel rotor construction allows heat generated from braking to radiate quickly through the aluminium core achieving surface temperature drops of around 50 deg C. When used with Ice Tech pads surface temperatures can drop from around 400 to 300 deg C, this provides great improvements in performance all round Ice Tech rotors achieve long pad life, less noise and less fade due to improved heat dispersion. Rotor contact surface has been developed for excellent pad clearing and cooling which increases pad performance and life.
This Shimano Deore BB52 HollowTech bottom bracket is specifically designed for use with chainsets that use a 24mm spindle.

This bottom bracket (BB) includes left and right-hand cups, spacers, an inner cover, and inner O-rings. Manufacturer's Part Number: BB52B Silver 68-73mm Hollowtech Eng
The stainless steel braking surface on the Shimano RT66 disc brake rotor improves its brake pad clearing in muddy conditions while aiding cooling during periods of sustained braking. To mount it onto your wheel's hub, it uses the popular 6-bolt mounting standard.
Available in two cassette ratios, the 11-25T is ideal for racing whilst the 12-2T8 is more suited to hill climbing sessions, such as sportives or endurance events.
These Shimano Tiagra flat bar brake levers have been designed specifically for flat handlebars when used with Super Shimano Linear Response (SLR) brake calipers. They offer great performance and comfort, plus come complete with both reach and cable adjusters for easy set-up Tech Tip: Although your flat handlebars may be 31.8mm or 35mm at the central stem clamping area, most flat bars have a standard 22.2mm diameter at the ends of the bars. These brake levers, as with most on the market, are designed for bars with this standard 22.2mm measurement at the end of the bars.
The junction is required for connection of rear mech, front mech, battery, and cable to battery indicator junction box with reliable and secure water resistant connectors. Cables sold separately.
Compatible with 7900, 7800, 7700, 6700, 6600, 6500, 5700, 5600 and 5500 brakes
The Side swing, side pull SLX double front derailleur decrease problems with tyre clearance and reduces cable friction, improving cable life and shift quality. E-Type Frame fit offers easy installation and absolutely optimum allignment first time. Designed specifically with modern trail bikes in mind, Shimano side swing technology front derailleurs increases tyre clearance by 15mm, while new cable routing resulting in the lightest shifting action yet. Specifically developed for 68, 73 mm and press fit 92 bottom bracket shells with a 48.8 mm chain line, making this front derailleur ideal for most modern setups.
Dynamic Chain Engagement (DECE) is used to hold the chain and help prevent chain jump out. This is achieved by using a broader and taller tooth profile in conjunction with a special hooked leading edge and alternate profiled tooth shaping. This provides superior chain retention, lower driving sound, increased durability and drag to a minimum.
Breathable, waterproof Gore-Tex® Performance Comfort liner keeps your feet dry. Natural nubuck leather with reinforced rubber toe box for protection and durability. Strategic ankle padding prevents debris from entering the shoe without interfering with pedalling movement. Vibram® outsole provides superior grip and foot control in all conditions. Mini Power Strap closure system with TPU heel provides firm 360 heel holding. Flexible half-length shank plate and shock-absorbing sole delivers trail walkability within a serious cycling shoe. Mid-top design offers added stability, ankle protection, and walking support.
Suitable for a wide use of cycling including cyclocross, touring, Audax and for drop bars and flat bars, the Shimano BR-CX50 model offers good mud clearance yet still maintains a low profile.
The Shadow features a super low profile design that reduces the risk of damage from trail side hazards and the single tension spring prevents contact with the chainstay resulting in a silent ride.
Although the crank arms and spider arms are noticeably bigger, which increases stiffness, the overall weight has dropped by 7g over the previous edition of Dura-Ace. The crankset has been adapted to work with disc brake road bikes that generally have 135mm rear hub spacing and shorter chainstays without the need to increase Q-factor thanks to its wider chainring spacing. The Compact version offered here features a 50.34T chainring profile to offer an excellent rider tuned gear combination for varied conditions from flats to high mountains. Please note: Bottom bracket is NOT included.
The Hyperglide (HG) sprockets on the Shimano SLX 11 speed cassette have a computer designed tooth configuration with contoured shift gates, resulting in a crisp smooth shift even under load. Close ratio gearing allows more efficient use of energy through finer cadence control. Also, the sprockets are cut away and drilled to reduce weight without reducing rigidity.
Finished off in the dark grey anodised paintwork, the Shimano Tiagra brake caliper is lightweight, durable and has a toe-in adjustable brake shoes. It's compatible with all the Shimano Linear Response (SLR) road bike brake levers. Please Note: The "sunken nut" mounting bolt that comes with this brake is the standard length and will fit most aluminium and carbon fibre frames. If you have an Aero-type carbon fibre frame with a very deep rear brake caliper mounting hole, you will need to purchase a longer sunken nut separately. Alternatively, if you are replacing like-for-like, you should be able to re-use your existing sunken nut.
The 9120 shifters feature a re-designed brake hood that is more comfortable to grip, especially for those with smaller hands. The shifters also offer up to 14mm of reach adjustment. The shifter hood has been slimmed down considerably from previous hydraulic STI shifters and is close in size and shape to the mechanical brake lever. The 9170 brake calipers have been tuned to perform optimally in road racing conditions. They feature the Shimano Flat Mount system for a sleek and aerodynamic profile and Ice Tech pads for improved heat dissipation.
