ProX Carbon Gravel Bike Frame With Micro Suspension System Plus Stem

Micro-suspension System

Progressive seatstay and chainstay tube shape, elastomer insert and small linkage inside form the Micro Suspension System of ProX carbon gravel bike frame PXG073S-D. Rear seatstay and chainstay are with specific carbon lay-up design to work like leaf spring, with flex zones to enable the movement of rear stays. Elastomer insert help to absorb the shocks that comes from rear wheel. The small linkage inside are with bearings which allows the rear stays to move freely. The whole system works together to provide better comfort and compliant performance in off-road conditions.

Material of elastomer: rubber
Hardness: (Shore A) 30°

Storage Room 

Having a storage room inside the downtube of a bike provides a convenient and integrated solution for carrying essential items.
Increased storage capacity: allows riders to carry essential small items such as tools, snacks, or small personal belongings without additional bags. It prevents them from getting lost or damaged as well.
Improved weight distribution: the weight is distributed lower and more centrally on the bike, which helps maintain a balanced and stable riding.
Cleaner aesthetics: remains sleek and uncluttered. It eliminates the possible obstacles items get in the way of the rider's legs while pedaling. 
Optimized aerodynamics: reduces wind resistance and improve efficiency, especially at high riding speeds. One small bag shown will come with frames for storage room inside the downtube.

Smart Mounts

ProX Carbon gravel bike carbon frame comes with multiple mounting mounts,  including fender mounts and bottle cage mounts. This allows additional accessories, such as fenders for wet weather protection and water bottle cages for long time rides. The postions of mudguard/fender mounts are as shown in the left. The rack mount on rear is not available due to the limited spaces on frame.

Fork Options

The default carbon gravel fork for LCG073S-D gravel frame is no-rivet hole on either side of fork leg. Considering some riders might plan to put small luggage or bottles on fork leg (would affect handling), there is also the other option for this gravel fork, that is, with 3-rivet hole on each side. If you prefer to have forks with 3-rivet holes, please let us know when placing orders.

Seatpost Options

PXG073S-D Gravel frame will come with seat post SP03(0mm offset) by default. If you prefer seat post SP02(25mm offset), please mention that you need seat post SP02 when placing orders. What's more, this frame is compatible for dropper post as well.

Gravel Frame With Drop Bar

Though stem is designed specifically to match LCG073S-D gravel frame to realize full hidden cable routing, you can choose different separated drop bars to match the stem. 
Our HBR05 handlebar is a good drop bar option for this gravel bike, which is designed with aerodynamic shape to reduce wind resistance and improve the overall aerodynamics of a bicycle and rider. 

Gravel Frame With Flat Bar

Some cyclists may prefer drop bars for the aerodynamic advantages while others might love MTB handlebar due to the multiple hand positions on long rides or paved sections. XC14 MTB handlebar is the second option for this gravel frameset.

Full Hidden Cable Design With Stem

There is no doubt that full internal cable routing looks rather pretty. PXG073S-D gravel carbon frame is with full hidden cable routing design(cable enter frame from under integrated stem). Perfect combination of professional geometry and full internal cable routing design. This design looks really nice and clean after whole bike assembled. 

A: Rear derailleur cable routing
B: Rear disc brake cable routing   

C: Front derailleur cable routing 

D: Front disc brake cable routing

UDH Hanger

The UDH(Universal Derailleur Hanger) creates a single hanger design that works on any bike for any derailleur generally. It'll also ensure perfect alignment during installation, so gear set up and shifting should be easier and crisper. What's more, if the chain jams, the hanger pivots backwards protecting the mech from being damaged. Besides, if you ever need replacement, it can be easily got since it is standard. 

Latex 3D Mandrel Technology

In the production of our gravel carbon frames, newest one-piece latex 3D mandrel and moulding technology are used.
Such technology helps to optimize the orthodromic and strength of carbon fiber, and avoid wrinkle inside (wrinkle is a key factor that may cause crack). Even using same material, the strength is improved 30%. 
To achieve same strength, tradition method requires thickness 1mm-1.2mm, while such new technology only requires 0.5mm-0.8mm thickness. Thus, we are able to make the frame about 15% lighter, given strength unchanged.
For 3D latex mandrel, it is smooth inside, no wrinkle or bubble as shown in the left pictures.
