Group 07 · Small accessories

Bike lights, bells, fenders and racks that bolt on the first time.

Small parts, high return rate. A bell that won't close round a 31.8 mm bar. A fender that rubs a 32 mm tyre. A rack with no eyelet to land on. A rear light whose strap won't reach round an aero seatpost. We source bike lights, bells, fenders and racks for riders across the United States from our Austin desk, and we check the mount before we quote. Lights and bells start from $11, indicative.

Lights and bells

USB-rechargeable front and rear lights, picked by lumen output and by how they mount. A front light for lit Austin streets needs around 200 to 400 lumens. Unlit country roads want 600 and up, and a battery that lasts the ride on the setting you actually use, not the flashing mode quoted on the box.

The mount is where most orders go wrong. Rubber strap mounts stretch over 22.2 mm flat bars and 31.8 mm drop bars both. Hard clamp mounts are cut for one diameter. Aero seatposts and D-shaped posts need a rear light with a wide strap or a saddle-rail mount. Tell us the bar and the post.

Bells come in brass and alloy. Brass rings longer and louder; alloy is lighter and cheaper. Both are sized by bar diameter, and the band on a 22.2 mm bell will not close round a 31.8 mm drop bar clamp area. We won't send a bell without that number.

Fenders and racks

Full-length fenders are sized by tyre width. The rule we work to: the fender should be roughly 10 mm wider than the tyre, so a 35 mm tyre takes a 45 mm fender, and there should be at least 6 mm of air between tread and fender all the way round. Less than that and grit packs in, the tyre drags and the stay snaps on the first pothole.

Rear racks are chosen by eyelet position. A frame with dropout eyelets and seatstay bosses takes a standard rack in ten minutes. A frame without them can still carry one through a seatpost clamp or a QR adapter, but the load drops. We quote the load rating the maker states and nothing higher. Most standard alloy racks are rated somewhere around 20 to 25 kg; we put the exact figure for the one we offer in the reply.

Disc brakes complicate things. A caliper on the seatstay often fouls the left rack leg, and a disc-specific rack or offset spacer fixes it. Send a photo of the left dropout before you order. It answers most of our questions.

Before you ask

The eyelet and clearance checklist.

Six things to look at on the frame. Five minutes with a ruler and a phone camera, and we can quote fenders or a rack in one reply instead of three.

  1. Dropout eyelets. Look at the rear dropout, just above the axle. Count the threaded holes. One is enough for a rack or a fender. Two lets you run both without stacking bolts.
  2. Seatstay bosses. Threaded bosses partway up the seatstays carry the top of a rack. Note whether they face out or in.
  3. Fork eyelets. For a front fender, check the fork dropouts and the crown. No crown hole on a carbon fork usually means a clip-on fender, not full-length.
  4. Tyre width. Read it off the sidewall, for example 700x35c or 35-622. The first number of the ISO pair is the width in mm.
  5. Clearance at the bridge. Measure from the tread to the underside of the brake bridge and fork crown. Under 12 mm and full fenders get tight.
  6. Brake type. Rim, disc on the seatstay, or disc on the chainstay. Disc on the seatstay changes which rack fits.

Process

From photo to tagged bag.

  1. You send the bike

    Make and model if you know it, tyre size, bar diameter, and photos of the rear dropout and the brake. The form below or an email to [email protected] both work.

  2. We run the fit check

    Eyelets, clearance, mount diameter and brake type. If something won't fit, we say so and name the adapter or the alternative.

  3. You get a reply in a business day

    Our target, Mon to Fri. Each part is listed with its check and an indicative price. That price holds for seven days.

  4. You confirm, we bag and tag it

    Bolts and spacers go in the same bag as the rack or fender. Nothing is charged before you confirm the reply.

Straight answers

What riders ask about accessories.

My frame has no eyelets. Can I still fit a rack?

On a steel or alloy frame, usually yes, through P-clamps or a rack that mounts at the axle. Load rating drops. On carbon, no. See the note above.

Do you sell dynamo lights here?

Dynamo lights depend on the hub, so they live with the hub notes on the city bikes page. This page covers battery lights.

Is the $11 the price I will pay?

It's where lights and bells start. The price in our reply is the one we hold for seven days. Nothing on this site is a binding quote.

Who is this page not for?

Anyone shopping for a bike computer, a GPS mount or e-bike lighting wired to a motor battery. We don't stock those. Bottle cages, kickstands and the parts on this page, we do.
