Bike gear repair and indexing in London

Shifting fixed from the cause

Bike gear repair and indexing in London

If your bike skips under load, hesitates when shifting or refuses to stay in gear, it needs proper diagnosis — not random barrel-adjuster guesses.

What we handle

  • Gears skipping under pressure
  • Slow or noisy shifting
  • Chain dropping
  • Derailleur not reaching all gears
  • Bent hanger symptoms
  • Worn chain or cassette
  • Cable and housing issues
  • Di2 or AXS shifting problems

Why workshop-led? Freddie helped pioneer mobile bike repairs in London, so we know exactly where mobile repairs are useful — and where they fall short. For diagnosis, upgrades, drivetrain faults, brake work and clean setup, a professional workshop with proper tooling wins.

We check the whole drivetrain

Cables, chain, cassette, chainrings, derailleur setup, hanger alignment and electronic shifting are all part of the diagnosis.

Questions riders ask before booking

Why do my gears slip when I pedal hard?

Common causes include worn chain/cassette, poor indexing or derailleur alignment.

Can indexing fix my gears?

Sometimes. If parts are worn or bent, indexing alone will not hold. We will tell you before doing unnecessary work.

Gear repair answer

Bike gear repair in London and South West London

If your gears skip, grind, hesitate or slip under load, Bike Clinique checks the cause before adjusting anything. Gear faults often come from cable friction, derailleur hanger alignment, chain and cassette wear, limit screw setup, damaged derailleurs or electronic shifting setup — not just indexing.

  • Gear indexing, cable and housing checks, derailleur setup and limit adjustment.
  • Chain, cassette, jockey wheel and chainring wear diagnosis.
  • Bent derailleur hanger checks and alignment where appropriate.
  • Shimano, SRAM, Campagnolo, Di2/electronic shifting and groupset-related repair support.
  • Clear quote before paid work starts; most workshop jobs are 24–72h unless parts or complex work are needed.

Gear repair questions riders ask

Can Bike Clinique fix gears that are slipping or not shifting properly?

Yes. Bike Clinique diagnoses and repairs gear indexing, slipping under load, bent derailleur hangers, worn chains and cassettes, stiff cables, damaged derailleurs and electronic shifting faults from its SW17 workshop.

Should I book gear repair or a full bike service?

If the only issue is shifting, book gear repair or start with the free safety check. If the bike also has brake, wheel, chain, tyre or bearing issues, Bike Clinique will explain whether a service is better value before paid work starts.

How long does bike gear repair take?

Most workshop repairs and services are completed within 24–72 hours unless parts or complex diagnosis are needed. Minor gear indexing may be possible same-day by request if the workshop has bench space.

Yes. Bike Clinique works on mechanical drivetrains, worn chains and cassettes, derailleur setup, hanger alignment, Di2/electronic shifting checks and groupset-related repairs.
