What kind of help do you need?

The SP3 is designed for everyday commuters, fitness riders, and recreational cyclists who want a comfortable and versatile bike.

Its lightweight construction and upright flat-bar riding position make it suitable for city streets, paved paths, neighborhood rides, and light gravel roads. It is an approachable option for newer cyclists while remaining capable enough for regular transportation and longer recreational rides.

The SP3 requires more assembly than X‑LAB’s road bikes, so we recommend having it assembled by an experienced bicycle mechanic or technician.

Riders with the necessary tools and mechanical experience can follow the written assembly guide and assembly video. Correct installation and torque are essential for safety. If you are uncertain about any step, have a local bike shop complete the assembly and perform a safety inspection before the first ride.

The SP3 has a maximum total load capacity of 242 lbs (110 kg). This includes the rider and everything carried on the bike, such as clothing, water, tools, accessories, racks, and cargo.

Exceeding the stated limit may affect handling, braking performance, and the durability of the bicycle or its components.

Yes. The SP3 supports full-length front and rear fenders, making it suitable for commuting and riding in wet conditions.

It is also compatible with universal rear racks that mount to the rear dropouts and seat stays. Fit can vary by rack, fender, tire size, and mounting hardware, so confirm clearance before installation.

Most local bicycle shops can perform routine SP3 maintenance, including brake adjustments, drivetrain service, wheel repairs, and general safety inspections.

For proprietary replacement parts, component customization, or warranty claims, we recommend working with an authorized X‑LAB dealer for model-specific guidance and support.

The SP3 supports tires up to 45 mm wide. This allows riders to choose between faster tires for pavement and wider, more heavily treaded tires for comfort and light gravel riding.

Actual tire width can vary depending on the tire model, rim width, tread pattern, and inflation pressure. Always confirm adequate clearance around the frame, fork, brakes, and fenders after installation.

Yes. The SP3 frame is compatible with most wired, wireless, and mechanical flat-bar groupsets from SRAM and other major drivetrain manufacturers.

A groupset conversion may require compatible controls, derailleurs, brakes, cassette, chain, crankset, freehub body, and related hardware. A qualified mechanic should confirm the complete parts list before installation.

The SP3 uses a standard threadless stem and a 31.8 mm handlebar clamping diameter. This makes it compatible with a wide range of aftermarket stems and flat handlebars.

Changing the stem length, rise, or handlebar width can significantly affect fit and handling. We recommend consulting a bicycle mechanic or fitter before selecting replacement components.

The SP3 uses a standard square-taper bottom bracket, providing compatibility with a wide selection of aftermarket cranksets and crank lengths.

Chainring compatibility depends on the crankset, chain line, drivetrain, derailleur capacity, and frame clearance. A qualified mechanic should verify compatibility before replacing these components.
