Key Features & Advantages
-
The carbon frameset is lightweight yet rigid, allowing responsive power transfer and superior climbing performance.
-
Mechanical disc brakes deliver consistent stopping power even in damp or wet conditions.
-
Shimano 105 R7000 groupset is a reliable mid-to-upper tier component series with smooth shifting across 2×11 speeds.
-
Aerodynamic design elements (e.g. aero handlebar, slim frame profiles) help reduce drag at higher speeds.
-
The sealed bearing wheel hubs improve durability and reduce maintenance frequency.
-
The 50/34T compact crank combined with 11–28T cassette gives a versatile gear range suitable for flat terrains and moderate climbs.
Usage Instructions & Tips
-
Before first ride, ensure all bolts (stem, seatpost, stems, disc calipers) are torqued to specified manufacturer values (commonly 4–6 Nm for cockpit, 8–10 Nm for seatpost clamp, etc.).
-
Install wheels correctly, check rotor alignment so disc pads do not rub.
-
Break in new disc pads by light braking over first 20–30 km to bed the surfaces.
-
Regularly inspect cable tension and wear; adjust shifting as needed to maintain crisp gear changes.
-
Clean the bike gently using mild soap/water; avoid high-pressure washers near bearings or the bottom bracket.
-
After rides in heavy rain or muddy conditions, dry and lubricate the chain and pivot points.
-
For storage, keep indoors or sheltered; avoid prolonged exposure to sun and rain which can degrade carbon and paint.
Precautions & Safety Notes
-
Always wear a helmet, gloves and protective gear when riding.
-
Before each ride, check for loose bolts, cracks in carbon areas, and brake/gear function.
-
Do not exceed the rider weight limit recommended by the frame manufacturer (typically ~100–120 kg, check with the brand).
-
Avoid striking the frame or fork against hard objects or curbs; carbon is strong but can suffer damage under impact.
-
If any crack or delamination is spotted on carbon, stop using and consult a certified repair centre.
-
Do not overtighten bolts beyond recommended torques — risk of damaging carbon threads or components.
-
Only use compatible spare parts; mixing unmatched parts (e.g. wrong disc rotor size, incorrect cassette range) may impair performance or safety.
