New Standards in the 1,000-Euro Class

Lots of bike for a great price – that‘s what has made the Copperheads not only the test winners for many years, but also the perfect sales hits. The cross-country classic, continually improved since 2007, leaves nothing to be desired in its price class in terms of frame design and equipment. Refined to the last detail, the BULLS best seller is the ultimate all-rounder for all areas of use where terrain, slope and moments of joy play a central role.

In its new evolution stage, handling has been improved once more. Small modifications of a frame concept that has proven its worth for years make the state-of-the-art all-rounder fresher and more agile as well. In combination with the stiffness increase by even more precise tube connections, the bike is rendered even more aggressive as well as agile on narrow trails.

The great detail work involved with the development of the Copperheads is not only reflected by the particularly clean looks due to highest processing standards; the spring fork of the Copperhead 3 has been developed exclusively for BULLS as well. Lower production tolerances and special seals ensure particularly sensitive reaction and best traction.

With their unmistakable character, the Copperheads make a clear statement in the class around 1,000 Euro: the combination of innovative frame design, highest-quality processing and top equipment once again sets new standards in terms of price-performance ratio.

Press Fit


press-fit bearing is pressed into the bottom bracket shell and not screwed, as

would be usual. The resulting force-lock fastens the bearing in the housing.

The press-fit inner bearing increases stiffness of the crank/inner bearing

combination, increasing the bearing's service life at a lower weight.

Tailored Chainstays


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 tall rider, specifically at inclinations. 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

Semi-integrated headsets with an inner diameter of 1 1/8 inch on top and 1.5 inch

at the bottom ensure best riding stability and excellent control head

stiffness. The stiffness of the fork profits from the more voluminous shaft,

and the forces are discharged into the frame better and with less strain on the

material through the higher-volume control tube.

Triple Butted


Butted" means triply conified wall thickness areas with a flowing

transfer. The strength is sufficient at the centre of a tube and the tube walls

can be kept thinner there. For best force distribution in the tube "Triple

Butted" tubes are also applied with different wall thicknesses at the ends.



technology effectively increases friction in the derailleur cage.

Impact of the chain when going downhill is minimised and the risk of the chain

jumping off is reduced by a special mechanism at the derailleur cage that can

be activated with a switch.

Internal cable routing

Internally placed shifting and brake lines ensure not only a clean and elegant look, but placement through the frame also protects all the important cables effectively against outer influences.


The travel of the fork is 100 mm.

Tubeless Technology

Tubeless riding clearly increases breakdown resistance, while also reducing weight and

rolling resistance. Additionally, there is some extra grip and comfort when riding at a low
