THE OPTIMAL RIM FOR SCHWALBE TUBELESS RACING BIKE TIRES
For safety and performance, the tire and rim on a road bike must be perfectly matched. This applies all the more to tubeless racing cycle tires. In addition to the classic hooked rims (crotched type), so-called "hookless" rims (straight side) are becoming increasingly popular in the racing bike segment. For safe operation, "hookless" rims in particular place high demands on racing cycle tyres. The models Schwalbe One TLE and Schwalbe Pro One TLE (from model year 2020) are designed to meet these special requirements, especially in the bead core area, and are therefore basically compatible.
SPECIAL NOTES ON HOOKLESS RIMS AND USE WITH SCHWALBE TLE RACING CYCLE TIRES:
- Hookless rims, also called "Straight Side", are characterised by the fact that the small hook at the end of the rim flank is missing.
- The official designation for tubeless hookless rims according to ETRTO is "TSS".
- The rim used must comply with the ETRTO standard for hookless rims (straight side).
- DThe specified air pressure of tyre and rim must be observed. If the specified maximum pressure of the rim is lower than that of the tire, the maximum pressure of the rim must be observed. This is the rule with tubeless hookless rims (TSS).
- The compatible tire widths specified by the wheel/rim manufacturer must be taken into account. Especially the minimum tire widths.
- If hookless rims are only designated by the manufacturer for tubeless operation, they cannot be used with tube-type tires and therefore bicycle inner tubes
-
Maximum air pressure recommendations for Schwalbe TLE / TLR tires on straight side / hookless rims are as follows:Tire width in mmMax. Air pressure in bar
18-24 5,5 bar 25-29 5 bar 30-34 4,5 bar 35-39 4 bar 40-44 3,5 bar 45-54 3 bar 55-64 2,5 bar 65-74 2 bar 75-84 1,5 bar
ADVANTAGES OF HOOKLESS
- Less weight compared to conventional "hook" rims.
- Hookless rims produce a rounder tire contour, which has a positive effect on the riding characteristics.
- Due to the comparatively high volume of tires on hookless rims, the practical air pressures are significantly lower. This increases comfort and grip.
