Road tubeless is a relatively recent innovation that uses an airtight rim and tyre without an inner tube. You need specific road tubeless tyres and in most cases road tubeless wheels, although you can switch 700c clincher rims to tubeless use with a conversion kit.

 

Road tubeless tyres can run at lower pressures than most clinchers without the danger of a pinch flat.

 

Road tubeless rims are becoming more and more popular these years.

 

NOTE:
 
‘Tubeless’ or ‘tubeless-ready’ rims are also available for road bikes, but they have yet to gain acceptance in the same way that they have among MTB riders. This is for a number of reasons. Firstly, one of the main advantages of the tubeless system – the ability to run tyres at lower pressures for improved grip without the risk of pinch or ‘snakebike’ flats – isn’t as important on the road, where tyres are generally run at much higher pressures. Secondly, road tubeless systems are regarded as offering few weight or performance advantages compared to tubular road tyres or even high-end clinchers. Many road tubeless systems weigh more than equivalent clinchers, while tubular setups will generally be even lighter. However development is continuing in this area so you can expect to see ‘tubeless road’ become a more common standard as manufacturers introduce lighter-weight, high performance tubeless tyres and rims.

ROAD BIKE WHEELS: IN-DEPTH

 

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).
