SR1 Disc Frameset – Blue Sky


Comfortable, versatile, fast: this is what we set out to achieve with our super-endurance SR1. We wanted a frame that will allow you to climb mountains, descend with confidence, pull along on rolling roads, confidently negotiate tight twisting corners and still allow you to be comfortable after an epic day in the saddle. Thanks to a carefully studied geometry, you can achieve a comfortable and efficient riding position and yet, fitness and leisure riders can experience performance that you would only get from a true race bike such as our race-bred FR1 and FR2.

Frameset Details

Uni-Directional Carbon

Interlaced unidirectional Toray carbon fibres create a composition whereby the direction and volume of the carbon layers vary according to those areas where they are applied. Reinforcing the areas of the frame that are subjected to greater forces, helps to decrease flex, dissipate vibration and improves power transfer.

Torayca T700/T800 High Modulus Carbon

High modulus fibres are generally characterised by being more elastic and so the main advantage is the ability to absorb vibration to which the frame is subjected and therefore ensures supreme levels of comfort.

Internal Cable Routing

Internally routed cables provide a clean, aerodynamic and sleek appearance while tucking cables away from external weather elements and so providing longer cable life expectancy. Added to this, SR1 retains internal piping thus making inner cable changes fast and easy: no more hunting around for cable holes.

Integrated Tapered Headset

With 1-1/8″ upper and 1-1/2″ lower bearings, tapered head tube designs are stiffer and stronger than conventional inline head tubes. Minimal flex at the front of the frame provides increased steering precision and accuracy.

BB86 Bottom Bracket

BB86 is one of the very latest bottom bracket standards and provides increased stiffness and therefore better power transfer. BB86 frames have a bottom bracket shell width of 86.5mm with an internal diameter of 41mm. All chainsets from Shimano, Campagnolo, SRAM, ROTOR and FSA will fit BB86 with an appropriate bottom bracket.

Di2 / EPS Compatible

Use mechanical or electronic gear system. The frame is also supplied with a full “closed” Di2 kit to ensure a smooth appearance.

Flat Mount Disc Brakes

With the option to run either a 140mm or 160mm rotor to both the front and rear, we can set up your Redchilli SR1 to match the discipline of cycling that you most enjoy.

Where your size and colour options are in stock, then most frames are despatched within 24 hours.

Most REDCHILLI frames are produced to order. This allows you to select your preferred colour scheme and paint finish though this does take a little time for us to produce. Therefore, delivery times are normally around 3-5 weeks though we will keep you updated of order progress. Custom Colour schemes normally take around 4-6 weeks for us to complete to your requirements.
