Precision Engineering for Elevation and Adventure
The Ascend Pro Series redefines high-performance wheelsets with a focus on weight savings, instant engagement, and all-terrain versatility. Crafted from T800 carbon fiber, these wheels combine exceptional stiffness-to-weight ratios with optimized aerodynamics, making them ideal for climbing, gravel grinding, and aggressive off-road excursions.
Key Features Overview
1. T800 Carbon Fiber: The Foundation of Lightweight Performance
The Ascend Pro’s rims utilize aerospace-grade T800 carbon fiber, known for its superior strength-to-weight ratio. This material allows the wheels to achieve remarkable rigidity while minimizing weight—critical for accelerating on steep climbs and maintaining control on rocky descents
.Weight Optimization: The 35mm and 40mm depths prioritize minimal mass (≈1250g per set), ideal for elevation-heavy routes.
Impact Resistance: Reinforced at the spoke bed and rim edge to handle gravel and trail obstacles
2. 54-Toothed Hub: Instant Power Transfer
The star ratchet system delivers near-instant engagement(6.67° freewheel rotation), ensuring power translates directly to forward motion during out-of-saddle efforts or technical climbs
Durability: The planar engagement mechanism distributes load evenly across teeth, reducing wear under high torque
Bearing Flexibility: Choose between Enduro steel bearings(maximal durability, ideal for wet/muddy conditions) or TPI ceramic bearings(ultra-low friction for competitive racing)
3. Aero 2.0 Spokes & Rim Design: Efficiency Meets Control
Aero Spokes: The 2.0mm steel spokes reduce drag while maintaining high tension, enhancing responsiveness during acceleration
Wide Rim Profile: The 22mm/24mm internal width supports wider tires (28-40mm for road/gravel; 35-50mm for adventure), improving grip and comfort on rough surfaces
Aero Optimization: The 28mm/30mm external width aligns with the 105% rule(tire width ≤ rim width × 1.05), smoothing airflow to minimize drag
4. Versatile Configurations for Every Discipline
Climbing (35mm/40mm): Emphasis on lightweight agility (≈1250-1350g); ideal for mountain races and steep gradients.
All-Round (45mm/50mm): Balanced aerodynamics and weight (≈1350-1400g); suited for rolling terrain and fast gravel
.Tire Compatibility: The wide internal width accommodates tubeless setups for lower tire pressures, enhancing traction and comfort
Why Choose the Ascend Pro Series?
Unmatched Responsiveness: The 54T hub + straight-pull spokes ensure zero power loss during aggressive climbing or sprinting
Durability Guaranteed: Enduro steel bearings withstand extreme conditions, while ceramic options maximize efficiency for racers
.Adaptable Performance: Select rim widths and depths to match your riding style—from hill climbs to backcountry exploration.

Maintenance Tips for Carbon Fiber Wheelsets
1. Regular Cleaning
Keep your carbon fiber wheelsets clean by regularly washing them with mild soap and water. Avoid using harsh chemicals that could damage the carbon fiber or the finish.
2.Inspect for Damage
Regularly inspect your wheels for any signs of damage, such as cracks, chips, or delamination. Early detection can prevent further issues and ensure your safety.
3.Proper Storage
Store your bike in a cool, dry place away from direct sunlight. Prolonged exposure to UV rays can degrade the resin in carbon fiber over time.
4. Brake Pad Maintenance
If you’re using rim brakes, ensure your brake pads are compatible with carbon rims and are in good condition. Contaminated or worn-out brake pads can damage the carbon surface.
5. Tire Pressure
Maintain the recommended tire pressure to avoid excessive stress on the rims. Over-inflation can lead to blowouts, while under-inflation can cause pinch flats.
Q&A
Question:What width tire for this product?
Answer:Here is our tire table for your reference,details are below:
Question:Does the product come with tire?
Answer:Not with the tire,we don’t product the tire,better yourself buy the tire what you like directly,without the tire also can save the international freight cost.

Question:How long will ship the product?
Answer:If standard product,we will deliver in seven days,if customized product,it need new production,it will take about two weeks.
Question:What is the carbon bike wheels quality benchmark?
Answer:the offset is +/-0.15mm,roundness is +/-0.2mm,the front spoke tension is around 90~120kgf and the rear tension is 110~140kgf.
Question:How is the Vat and duty for the buyer from european union countries?
Answer:Paying tax and duty if any is a civic obligation,and ultimately these contributions are returned to you through government-provided social public services and welfare.

Question:Can you accept the small or medium order for the OEM project?
Answer:Yes,no minimum order Quantity request
Question:What is the rider weight limit on the product?
Answer:The weight limit is 80~100kgs for the rim height less than 35mm and 100~120kgs for the higher profile.
Question:How many bar range for the tire inflation?
Answer:The tire pressure is complicated,here is a maximum recommended air pressure of 51 PSI if you use tires in the range of 40-44 millimeters, but if you use extra wide tires exceeding 50 millimeters, the air pressure will drop significantly to only 36 PSI. Bola online tool takes into account the weight of riders and bicycles, and the results are very interesting; It recommends a front wheel pressure of 25 PSI and a rear wheel pressure of 27 PSI, which is lower than the pressure used in gravel bike racing.
