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 .
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
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
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
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
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.
