Copperhead RSi 29

When faster, lighter, stronger is needed

The 2016 BULLS Copperhead 29 RSi is the newest member to the Copperhead family. The RSi takes over as the highest model the Copperhead series comes in and leaves nothing to be desired. This best seller has been refined with small modifications to the frame’s geometry to maximize traction and perform more agile than ever. Frame is constructed with 7005 Triple Butted Aluminum and offers internal cable routing, a tapered head tube, and a press fit bottom bracket shell. We paired the frame to a FOX 32 Float fork with a remote lock-out to adapt to varying trail conditions. Through axles on the front and rear are standard with the RSi making it more rigid, safer, and stiffer. An all new Shimano Deore XT M8000 groupset gives an even better riding experience. Apart from being an 11 speed, one of the many highlights is the side swing derailleur making shifting easier and more stable. The bike’s geometry still has marathon use in mind while offering reliability and all-out speed. Our rider-tuned BULLS Copperhead 29 RSi puts you in control like never before.

Specifications subject to change without notice.
11-Speed Drive Train
The 11-speed drive train is used in both Road and MTB models. The cassette has 11 gears instead of 10 gears. This new 11-speed cassette has proved to improve efficiency and ultimately power thanks to its greater selection of gears
100mm
Full suspension bike with a rear shock of 100mm travel.
Triple Butted
To save even more on frame weight, the double butting process is refined by stepping down the material at the ends of the tube. This means the butting starts out in the standard, double-butted manner but then is thinned before stepping down again to the normal tube wall thickness. In a cutaway, the inside of the tube looks like three terraced rice paddies on a hillside
ICE Technogy: Freeza
With an increased surface area for heat dispersion, Shimano's new ICE-TECHNOLOGIES FREEZA rotor has realized the ultimate in heat control. As a result, the 50C reduction in heat gives greater durability and longer padís life
Press Fit
Press Fit bearings are pressed directly into the frame, rather than screwed. The press-fit inner bearing guarantees higher bicycle stiffness, thus increasing the lifespan of the bearings and overall lower weight
Shimano Shadow Plus
Shimano's Shadow Plus clutch mechanism prevents the lower arm of the derailleur from pivoting forward, meaning that the chain is kept under considerably more tension. The claimed benefits are many: Less chain slap, fewer dropped chains, more stable and accurate shifting over rough terrain and ultimately a much better and quieter ride
Tailored Chainstays
Higher frames require longer chainstays. The result is a much improved climbing capacity, which is relevant in large frames. After all, the centre of gravity clearly shifts backwards with a taller rider, specifically during the climb. Taller riders also need more space since they usually have longer feet, and for the longer cranks to avoid touching the chainstays with their heels
Tapered Steerer
This is semi-integrated headset with an inner diameter of 1 1/8 inch at the top and 1 1/2 inch at the bottom. This ensures best riding stability and excellent control head stiffness. The biggest shaft results in stiffer fork and frame as riding forces are spread more evenly thanks to a thicker head tube
Thru-Axle
The main advantages of this axle system are stiffness and strength, which added together results in a safer bicycle. It has a clear advantage on disc brakes over its traditional quick release counterpart as it allows for easier and more precise wheel mount/dismount operation
Internal Cable Routing
Internally routed shifting and braking lines ensure a clean and elegant look while ensuring a better protection to all important cables
Tubeless Technology
Tubeless clearly decreases rolling resistance of the wheels while reducing the overall weight of the bicycle. Additionally, there is some extra grip and comfort when riding at a low pressure
