Seven part groups for road, city and kids' bikes. Each one below carries the spec that has to match, the price it starts from and the page with every line. Nothing here goes in a cart. You send the bike, we check it and reply within one business day.
Part groups
Every group has one or two figures that decide whether a part fits. Get those right and the rest is preference. Get them wrong and the part goes back in the bag.
Bike drivetrain parts for 8 to 12 speed: chains, cassettes and freewheels, rear derailleurs and hangers, bottom brackets and bearings. The group where most wrong orders happen, because a 10-speed and an 11-speed chain look the same until they skip.
Chains, cassettes, derailleursComplete wheelsets in 700c, 650b, 20 in and 16 in, plus hubs, spokes and brass nipples. A wheel has to match the frame three ways at once: ISO size, axle standard and brake type. Spokes are cut to a length we calculate from rim ERD and the hub flange figures.
Wheelsets by ISO sizeRoad and city tyres from 700x25c to 700x40c, kids' sizes 20 to 24 in, inner tubes, valves and rim tape. We size tyres by ISO number and frame clearance, and tubes by rim depth and the hole drilled in the rim. The sidewall marking you read off at home is the most useful thing you can send.
700x28c road tires and tubesDisc brake pads and rotors, rim brake pads and calipers, levers and hydraulic bleed kits. Pads are matched by caliper model, rotors by diameter and mount, calipers by reach. Hydraulic parts wait until you name the fluid on the lever.
Disc brake pads and rotorsBar tape, grips, stems and headset spacers. Tape comes in cork, synthetic and leather-look from 2.5 to 3.5 mm thick. Grips fit 22.2 mm flat bars. Stems are picked by bar clamp, length and steerer size, in that order.
Bar tape, grips and stemsInner cables, housing, ferrules, chain lube, grease and brake fluid. The cheap parts that make expensive ones work. A brake cable will not pass through shift housing and a shift cable in brake housing feels like mush, so we sort both by diameter first.
Bike cable and housing kitLights, bells, bottle cages, fenders, racks and kickstands. Small, but each one bolts to something. Fenders need clearance over the tyre, racks need eyelets where the rack expects them, and a bell needs the right bar diameter.

These are the columns in every reply. Read the ones that apply off your bike before you write and we can usually quote in one go.

Start from the bike. Each page lists the parts that wear first on that kind of bike and the specs that usually go with them.
Speed count, wheel size and what's worn. We reply Mon to Fri within one business day with the part, the check and a price we hold for seven days. Or call +1 (565) 555-2353.
