1. Avoiding detrimental effects on aerodynamics

 

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 .

 

2. Lighter and Cheaper

 

The weight of carbon tubular wheels are lighter and its price is cheaper . A lighter wheel will accelerate faster and will be much easier to ride up hills . This means that if you are sprinting and hill climbing a lot , a shallower rim , like a 38 will be best .

 

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. Easier to control


Tubeless-ready wheels can still be run with inner tubes just like always but they can also be easily run without inner tubes, as tubeless.


 

Lightweight, strong and stiff rims can be one of the best performance upgrades for your road bike, with reduced rotational weight offering increased speed for less effort and improving a bike’s climbing, acceleration and handling abilities.

 

Meanwhile deep-section aero rims are designed to offer straight-line aerodynamic advantages for competitive racing, although they can compromise overall handling in crosswinds (depending on their depth).

 

While many road rims are made from aluminium alloy, the upper end of the market is dominated by premium carbon hoops, most of them with an aero profile of some degree. However these are more commonly sold as complete wheelsets.


 

WHICH ROAD RIM IS RIGHT FOR YOU?

 

Road bike rims differ in many ways, from size (diameter and width) and construction (materials used, number and type of spokes) to intended use (all-weather training or race day performance).

 

The choice ranges from good-quality budget and mid-range aluminium offerings to the latest generation of carbon fibre aerodynamic wonders. The right rims for you will depend not only on your budget but also on the type of riding you enjoy.

 

Sportive and leisure riders, for example, may be served best by aluminium alloy ‘all-rounder’ rims offering a balance of light weight, durability and ease of repair, while competitive riders may choose to invest in carbon fibre rims as part of a ‘race day only’ wheelset which delivers stiffness, light weight and superior aerodynamics – but at a price.

 

 

 

Construction


A typical road bike rim consists of an aluminium or carbon fibre hoop laced to the wheel hub with spokes, the number, pattern and type of which depends on the design and intended use of the wheel. Rims may be designed to take the more common clincher tyres or the tubular type (‘tubs’).

Rims also vary in construction and materials – the traditional ‘box-section’ rim is still found on wheels at the lower end of the price scale and is ideal for leisure riding, commuting or touring, but most mid-range wheelsets and up now use deep-section aero rims for added stiffness, strength and aerodynamic performance.

 

Sizing – diameter, width and depth


Road bike rims come in a variety of sizes with the most common diameter being 700c (for most adult road bikes) and 650c (smaller racing bikes for juniors and ladies, some high-performance time trial and triathlon bikes).

Rim widths also vary, with narrow rims – for narrow tyres that can be pumped to a high pressure for more speed – the standard for high-performance bikes and commuters/tourers requiring wider rims.

Rim depth is also to be considered. The new generation of aero rims and wheelsets feature deep-section rims for improved speed and stiffness but as they affect handling, ultra-deep section rims may not perform well under specific conditions (i.e. when it’s windy).

NOTE: Sizing for tubular rims is different to clincher rims with manufacturers still using imperial sizes (26” equates to 650c and 28” to 700c). The large variety of wheel sizes and measuring methods has always given rise to confusion, leading to the development of a universal sizing system by the ISO (International Organisation for Standarisation). This system was formerly known as the ETRTO system, developed by the European Tyre and Rim Technical Organisation.

Manufacturers now also provide an ISO/ETRTO number which gives a rim’s width (measured between the flanges) and diameter (of the bead seat) in millimetres. For example, a 700c wheel has a diameter of 622mm, so the ISO/ETRTO number of a 700c wheel with a 15mm rim would equate to 622×15.

If you are unsure of the exact sizing of a wheel rim or tyre to match, check for the ISO/ETRO number to be certain.
