1. High Inflexibility And Strength Rim


Material is crucial for a rim , so we select material very carefully . They are Japan , Taiwan and China Mainland . Toray Japan is the largest and best carbon producer in the world , their products are used in many of the airplanes . The carbon we use is T700 from Toray , although Toray's price are almost 2X than those from Taiwan and 3X than China Mainland , comparing the durability and stiffness it brings , it is definitely worthy .


2. Less Affected By Crosswinds


The more a wheel becomes aerodynamic for going forward , the more it can be negatively affected by cross-winds , or winds coming from the side . 38mm depth rim will less affected by cross-winds , or winds coming from the side than more deeper rim .


3. With Basalt braking surface


Baslat material can anti high temperature 160-210 degree , it can slower the wheel's speed soon and stop the bike in shorter time , and would not tear or wear out the brake track .


4. Practical


As a clincher rim , you can simply replace the tube if you puncture making them better for training and all-round use as well as most racing .



COMMON TYPES


Traditional vs aero


There are two basic designs of rims, named after their cross-sections – the more traditional ‘box-section’ (roughly square or rectangular) rims and the ‘aero’ shape deep-section rim (roughly triangular).
The deep-section rim has a number of advantages – it is stronger and laterally stiffer, meaning less spokes can be used to build the wheel, and its aerodynamic profile provides a speed advantage by reducing drag forces. Deep-section rims can also be built using carbon fibre for a reduction in weight and improvement in stiffness, further boosting acceleration and speed.
However the major disadvantage of deep-section rims is that the steering and handling can be impaired while riding in a cross-wind; the deeper the rim, the worse the effect (taken to extreme by disc wheels which are generally only used indoors or in flat calm conditions).
Therefore many riders may opt to choose wheels with different rims or rim depths for different conditions or race situations.
Leisure riders and tourers may appreciate the comfort and simplicity of traditional box-section rims, while aero rims with a lower profile may be ideal for sportive events, climbing or all-round race riding as they provide a balance of improved stiffness and reduced weight without the trade-off of poor handling.
Meanwhile for time trials in calm, flat conditions, track racing and even triathlon stages a set of proper deep-section aero wheels (or even disc or baton wheels) may come into their own.


Tubular vs clincher


Finally road bike wheels are also available with tubular or clincher rims to fit two different types of tyres.
Clincher wheels and tyres (used with inner tubes) are by far the most common type. This is where the rim of the wheel features a ‘hook’ into which sits the bead of a clincher tyre.
Tubular tyres are sealed units with an inner tube sewn into the casing of the tyre. Rims for ‘tubs’ do not have the hook for the bead (and so are lighter), the tyre being glued in placed with tubular cement or secured us.
