Mino Link 

Fine tune your bottom bracket height by a couple millimeters, and tweak your headtube angle 0.5° 

Leverage rate 

Flip the chip to get more progressive leverage rate, perfect for coil shocks and added bottom-out resistance

Customize your ride 

Room for longer droppers, coil shocks, and forks up to 170mm

Refined suspension

Rail is made for ripping down and hammering back to the top to do it again, so we increased the anti-squat for better pedaling efficiency on the ups and lowered the leverage rate to maintain a plush feel in rowdy terrain. Need more end-stroke support or want to run a coil shock? No problem. Flip the chip at the lower shock mount to get a more progressive leverage rate.

Quarq TyreWiz

TyreWiz lets you check tire pressure without even pulling out the pump. Once you enter your desired pressure in the SRAM AXS app, all you have to do is check the lights on the valve stems — green means go, red means pump up before you roll.

TK25-Rail+-B2CEditorial-Bosch-Control-Marquee-5

Built to elevate your e-bike experience, Bosch’s eBike Flow app lets you take control of your ride. It works with both iOS and Android phones, auto-updates your remote and display with the latest features, and the home screen gives you a quick overview of your most important ride data like battery status and range.

Customize your assist

Fine-tune assist modes to your liking. Get the most support on your climbs or stretch out the miles on longer rides with more efficient power use.

Set your record

Tracking starts as soon as your foot hits the pedal and pauses automatically when you take a break. Plus, your data synchronizes with integrated apps like Apple Health in real-time.

Tech built for Trek

Trek-exclusive integration means the eBike Flow app automatically recognizes your Trek e-MTB, provides service recommendations, and will even help you find your local Trek shop.
