Karl Platt is riding a revised Bulls Wild Edge frame from last year. The new frame features a modified suspension linkage which now uses bearings replacing the bushings found on the previous bike. The chainstays and seatstays have also been modified to allow for a shorter rear end. There is a flip chip on the top tube mount to allow for the frame to accept metric or non-metric sized shocks.

SRAM might have the gold bling but Shimano has the (crank) shine. BULLS ride Shimano using XTR drivetrain and brake components. Karl has chosen a 36-26 double chainring configuration with an 11-40 cassette. Shifters and derailleur are Shimano's electronic Di2 type with a Stages XTR crank arm.

Karl has set up his cockpit with FSA's K-Force handlebar measuring 700 mm and a 90mm Force Light carbon stem. The seat post is a BULLS creation, the compliant Duroflex provides some added comfort. Sahmurai Sword bar ends conceal a plug tool with ESI grips and road bar tape providing comfort on the handlebar.

every year around Epic time i'm just gobsmacked that they don't have an agent in this country.


the Epic is their biggest race, they have been up there so often. yet they don't sell their own bikes!

I live in Europe and I've never seen a Bulls bike in the wild.

I like their bikes very much. The have guys riding in the EWS so proven machines but I think the problem is the same as many

other brands you don't hear about in South Africa, the market here is too small. When last did you see one of these on the road;









Just too many companies and too small a pie here in SA.

They did try to sell the Bulls brand here a few years ago, just dont think it got enough traction.

No bar ends this year, I seem to recall he used them previous times.
