Keep your bike in good condition, piece by piece.

Check Compatibility

Before buying a part, check its compatibility with your bike: this is the main source of error. The diameter and width of the tyres can be found on the sidewall of the current tyre; the number of speeds determines the chain and the cassette; the type of mounting for the brake discs, Center Lock or six-bolt, depends on the hub; the pads correspond to a specific caliper model. If in doubt, note the references printed on the original part.

By Type of Part

Spare parts are organised by type:

The bike is also available in road, mountain bike, BMX, city, with equipment, on the bikes page.

Worn Parts

Some parts wear out and need regular replacement. Disc brake pads, such as the Shimano B05S in resin or metal pads, need changing when the lining gets thin; brake shoes for rim brakes, like Shimano R55, when their grooves disappear. Tyres wear in the centre of the tread: the Continental Ride Tour, reinforced, resists punctures in the city. The chain and cassette wear out together. Automatic pedal cleats from Shimano wear down while walking and need replacing when releasing becomes imprecise.

Tools and Comfort

The torque wrench Super B tightens each screw to the torque specified by the manufacturer: essential on handlebars, stems, and carbon seat posts, which can crack with excessive tightening. The sealant Pirelli seals small punctures in tubeless tyres. For comfort, the saddle is chosen based on hip width and position: the Chromag Semenuk, open in the centre, relieves sensitive areas. The child's front saddle Shotgun, fixed to the frame, allows you to take a young child on a ride. The headset and fork should be replaced when the steering becomes loose.

Frequently Asked Questions

How do I read a bike tyre size?

The size is shown on the sidewall, often in two formats: either in inches or millimetres, and a two-number code giving the width followed by the diameter of the rim in millimetres. This second code, the most reliable, allows for comparisons across all brands.

When should I change bike brake pads?

Replace them when the lining becomes very thin, around half a millimetre, or if braking becomes noisy or less effective. Also check the thickness of the disc, which wears down over time.

Center Lock disc or six-bolt: how to tell?

Look at the hub: the Center Lock mount secures with a central notched ring, the six-bolt mount with six small screws around the axle. The disc must match the hub unless using an adapter.

Why use a torque wrench on a bike?

It tightens each screw to the torque specified by the manufacturer, without excess or shortage. This is essential on carbon parts and small screws on the stem or saddle, which can crack with excessive force.

What is a puncture prevention sealant for?

Injected into a tubeless tyre or a suitable chamber, it instantly seals small punctures caused by thorns or flints. It dries over time and needs replacing every few months.
