Increasing compliance and comfort while still maintaining the stiffness of a traditional hardtail. Utilising a pivot system that ‘decouples’ the seat tube from the top tube, the IsoSpeed system allows the seat tube to ‘flex’ with the road or trail bumps. The IsoSpeed system has been developed and refined by Trek to provide their endurance road and mountain bike hardtails with a more compliant rear end.
Using two suspended pivots, the Full Floater equipped rear suspension is suspended, which greatly improves pedalling efficiency and gives you the impression of a bottomless feeling to your suspension. Trek’s Full Floater suspension system is found on all Trek’s full suspension mountain bikes and is designed to create a ‘floating’ rear suspension. Designed based on technology from Formula 1, the RE:activ system is tuned to provide ‘regressive damping’, which creates a stiff and stable pedalling platform while still allowing a reactive suspension system when the trail gets rough. Trek works in close collaboration with automotive suspension company Penske to create the RE:activ suspension damping system. Out on the trail this means your suspension keeps working while you brake, which creates a more controlled ride.
ABP is Trek’s way around this problem and uses a specific rear pivot placement that separates the rear brake calliper from the frame and suspension.
When the brakes are engaged, the suspension stiffens and the bike often loses traction. For years, full suspension bikes have been hindered by braking forces affecting the suspension. ABP – Active Braking PivotĪBP or Active Braking Pivot technology is found on all of Trek’s full suspension mountain bikes. Understanding the different technology options and understanding how they change your ride while out on the trails is an important step when purchasing a mountain bike. Trek’s mountain bike line is filled with technological features to help you go fast and stay in control and comfort out on the trail.
