Schwalbe has up to date its top-of-the-range gravel race tyres and added a mannequin new mannequin – the G-One RX Expert – to the set.
The G-One RX Expert incorporates a new tread sample for rockier and muddier circumstances, whereas the G-One R and G-One RS tyres have been outdated by the G-One R Expert and G-One RS Expert, respectively.
All three tyres get a mannequin new developing, which is claimed to provide elevated puncture safety, whereas reducing rolling resistance by 10 per cent in contrast with the earlier G-One tyres.
The tyres could also be found from for the time being, in black and tan sidewall colourways, costing €74.90 / $83.39 (UK costs are TBC).
G-One RX Expert tackles technical terrain
Schwalbe says the mannequin new G-One RX Expert tyre “completes” the G-One tyre line-up, providing most likely in all probability probably the most aggressive tread sample of the differ.
Central boomerang-shaped parts are designed to provide low rolling resistance, with extended teardrop-profiled intermediate knobs are claimed to strengthen structural assist beneath load.
The outer sample alternates between longitudinal and curved blocks, which is likely to be talked about to strengthen grip and stability when cornering rapidly on troublesome terrain.
Tread depth is claimed to sit down between the model’s G-One Chunk and Ultrabite tyres (which maintain as a mid-tier providing), whereas they’re extensively spaced to strengthen mud-shedding.
Rolled out all by the differ
Beneath the pores and pores and pores and skin, a mannequin new Race Expert developing has been developed to decrease rolling resistance and enhance experience consolation, whereas fortifying puncture resistance.
This replaces the Tremendous Race developing, as utilized by the G-One R and G-One RS, with the selection G-One R Expert and G-One RS Expert tyres furthermore utilizing the mannequin new developing.
The carcass continues to function a 67 threads-per-inch casing and three-layer sidewalls, nonetheless has been widened, together with the V-Guard vectran puncture safety belt (that is now 25mm broad in a dimension 700x40c, up from 20mm).
This extension means the belt overlaps the carcass, which Schwalbe claims contributes to decrease rolling resistance in contrast with the Tremendous Race design (which noticed a definite phase between the belt and carcass overlap).
Schwalbe’s drop-bar product supervisor, Jakob Maßen, says the model was shocked to look out extra provides proved to be extra environment nice in testing, nonetheless says small provides financial monetary financial savings elsewhere work to counteract the extra weight.
The Addix Race compound has furthermore been tweaked – Schwalbe claims a mannequin new approach leads to a ten per cent low value in rolling resistance when blended with the occasion modifications, and improved grip on the shoulders.
The mannequin new tyres furthermore see the introduction of black-sidewall choices (beforehand, the G-One R and G-One RS tyres had been solely in the marketplace with tan sidewalls), and a mannequin new 700x50c dimension all by the differ.
Schwalbe G-One Expert line differ
Schwalbe says each tyre is ETRTO-compliant and could also be utilized with hookless rims (furthermore adhering to those requirements).
It says it exceeds enterprise requirements in reliability testing, subjecting its gravel tyres to its inside commonplace of 1.6x most acknowledged stress for one hour, as an alternative of the established 1.1x most stress for 10 minutes.
In keeping with ETRTO requirements, Schwalbe’s ‘TLE’ (Tubeless Simple) nomenclature is being phased out and adjusted by ‘TLR’ (Tubeless Prepared).
Schwalbe says every tyre is created utilizing recovered Carbon Black (versus virgin Carbon Black – a key issue of tyre rubber), which leads to an 80 per cent low value in carbon dioxide emissions for that issue.

The G-One RX Expert, G-One R Expert and G-One RS Expert tyres could also be found from for the time being, all costing €74.90 / $83.39 (UK costs are TBC) in each permutation.
