MTB: Technik-Optimierung

Speed is made when you're not braking: how momentum, line choice and dosed braking windows make you faster without one extra watt.

Sport: MTB · Level: Intermediate

Introduction

"How do I get faster on the trail without pedalling harder?" The honest answer: by no longer braking away your own speed.

Two measured findings make that concrete. First: in an XCO race about 27 percent of the time is spent not pedalling at all — more than a quarter of your ride time is decided not by watts but by rolling, line and braking behaviour. Second: brake work, brake time and brake power correlate significantly with ride time — inexperienced riders measurably brake away more time and energy than necessary.

That's the best news for any intermediate: between you and a faster lap stands no extra training, but momentum management — the art of preserving speed instead of constantly destroying it and buying it back. That's exactly what we'll train now, with a measurable before-and-after.

What You Need

Step by Step

1. Ride the Brake Audit

Ride your reference loop at normal pace and watch yourself honestly: where does your finger rest on the lever permanently? Where do you drag "just in case" without a corner or obstacle demanding it? Stop the total time.

Most intermediates discover constant braking they were never aware of in this audit — exactly the pattern measurements show in the inexperienced: lots of brake work over a long time with little effect.

2. Condense the Braking Windows

Now you replace dragging with windows: before every key section you brake short and hard down to the required speed, then the brakes stay open. Braking in racing is frequent and finely dosed — but in good riders it concentrates into clearly bounded zones rather than the whole trail.

Your goal: less brake time at higher brake power per application. If there's no free rolling between two windows, they weren't windows.

3. Smooth the Line

Momentum doesn't just die at the brake, it dies on the ground too: hits and vibration demonstrably cost energy because they raise your muscle activity and fatigue you. So choose the calmest line, not the shortest — around the root field instead of through it, over the smooth berm edge instead of through the brake hole.

A smooth line at the same speed feels slower but is faster, because it preserves your pace instead of chopping it up.

4. Exploit Rolling Sections Deliberately

Define sections on your loop where you neither pedal nor brake — gentle descents, rollers, run-out zones after corners. Here you work only with body position: low and central through dips, actively building pressure where the trail allows.

That good riders don't pedal for over a quarter of race time isn't laziness, it's efficiency: every preserved bit of momentum is energy you get back on the next climb.

5. Compare the Time

After two or three practice sessions, ride the reference loop again and compare the time — not the feeling. Momentum riding often feels unspectacular precisely because the frantic brake-accelerate cycles are gone. The clock tells you the truth.

Also note how fresh your arms are at the end: less braking and a smoother line lower the holding fatigue too.

Common Mistakes

Safety Notes

Momentum riding does not mean skipping braking zones: before blind spots, oncoming traffic and hiking trails you brake, full stop. Raise speed only within sight lines and only on trails you know.

Watch your fatigue: when modulation fades, end the fast runs — loss of control under fatigue is the classic crash cause. And a full-suspension bike is no free pass here either: it damps vibration but doesn't automatically make you faster.

Pro Tip

Ride a practice lap entirely without pedalling — only rolling, pumping and dosed braking windows. What sounds like play is the most honest momentum training there is: without pedals as a correction tool you instantly feel where your line and braking destroy momentum.

Downhill pros use exactly these no-pedal runs to compare lines. One lap a week is enough to permanently sharpen your feel for preserved speed.

FAQ

How do I brake correctly on a mountain bike — front or rear?

With both, but the front brake delivers most of the deceleration while the rear stabilises. The beginner pattern — rear-heavy, early and long — is measurably slower. Correct means: short, forceful braking windows before the key section, then brakes open and let it roll.

Should I brake with one finger or two?

With one — the index finger, resting on the lever permanently. Modern disc brakes deliver more than enough power with one finger, and the remaining four fingers hold the bar, which clearly improves your control in rough terrain. Two fingers on the lever are usually a sign of badly adjusted or weak brakes.

Why does my rear wheel keep locking up?

Because too much braking share sits at the rear, and with an unweighted rear end the tyre is quickly overwhelmed — the classic inexperienced braking pattern. Shift more braking force to the front, finish braking earlier and choose grippy ground for your braking windows instead of loose rubble in the corner.

Why am I slower through corners than others?

You're probably destroying momentum before and in the corner through long dragging — more brake time measurably means more time at low speed. Then there's the line: chasing the shortest line frantically sends you through the impacts and bleeds speed. Brake short and hard beforehand, smooth line, let it roll.
