With all of the hullabaloo round hookless highway tubeless, the brand new Goodyear VectorR highway bike tires look like a well timed launch. Developed together with Zipp particularly for his or her 303 wheels, it’s an fascinating partnership that delivers a really optimized system.
The important thing distinction is that the tread cap and casing is all particularly made for Zipp 303-series wheels. The result’s the VectorR 700×30 tire measures a real 30mm on Zipp’s 25mm inner rims.
The bead design is optimized for higher fitment with hookless wheels, and extra particularly for Zipp’s 353 NSW and 303 Firecrest wheels.
It’s not simply fitment for security causes, as a result of, if we’re being sincere, hookless rims for highway are principally high quality so long as you adhere to advisable tire pressures and set up tips. In case you’re involved about it, then there’s no want to purchase Zipp wheels or Goodyear tires optimized for them and you may go straight to the feedback to register your issues.
No, right here, it’s largely about aerodynamics. Goodyear says that commonplace 28mm vast tires are designed for rims with 19mm inner widths, yielding a tire that measure proper about 28mm vast. That places its tread cap the place it must be for straight-line and cornering grip, and the casing development is designed to assist that.
However Zipp’s rim profiles are a lot wider (as are many different manufacturers nowadays). Put that very same 28mm tire on a wider rim and it often stretches to about 30mm vast. Its profile will get distorted and the tread cap isn’t vast sufficient to completely assist deep cornering. However, oddly, aerodynamics are barely improved.
So, why not optimize?
With these new VectorR 30mm tires, the tire development is designed to create an optimum profile, tread contact patch, and aerodynamics. The tire’s precise width is 30mm, which matches the outer rim width for a greater look and streamlined airflow.
Not solely do they match the rim, their sidewalls and development are designed to assist the rider and bike weight with the advisable decrease tire pressures.
What about different manufacturers of wheels?
Goodyear calls this their Fitment Sequence, which “make the most of strategic partnerships toe develop trade main tires that embrace rising applied sciences and traits with out compromise.” It’s a systems-based method to tire growth that optimizes round a particular use case. On this case, it’s the Zipp 303 NSW/Firecrest rims.
Past that, it’s a bit fuzzy. Zipp isn’t endorsing them to be used on different rims however advised that, technically, they’re suitable with Zipp’s 23mm inner rims, too, (just like the 404-series) however they’re extra suitable with their 25mm inner rims.
Goodyear lists their specs as “designed to measure 30mm on a 25mm TSS rim”, but additionally point out that they’re “to be used solely with Zipp 622×23-25 TSS rims and had been designed solely across the Zipp 622×25 TSS rim”. So, as much as you if you wish to run them on different wheels…it gained’t void a guaranty or something, however…
What about pace & grip?
It’s not nearly fitment. In addition they focused pace, rolling resistance, and grip. Zipp says they’re about 1w sooner than the Continental tire they’ve at all times used for testing, which they’ve at all times discovered to be the quickest tire they’ve examined, and a great benchmark.
In addition they have low rolling resistance, which, when mixed with the aero positive aspects, places them general on par with the pace of the Conti. For grip, they bought nearer to Conti’s dry grip, however exceeded each it and the Vittoria for moist grip. So, mainly, it’s an incredible tire.
Coming in two variations
There are three variations of the tires, two 30mm vast and one 35mm vast. Whereas the names indicate there’s one particularly for the NSW wheels, that’s actually simply a sign that it’s the higher-end tire. You may put it on the 303 Firecrest, and so forth., if you would like.
VectorR NSW 30
The light-weight racing and climbing choice, it has a 150tpi short-ply casing with their R:Defend puncture safety layer underneath the tread cap. They’ve their Dynamic:UHP compound for low rolling resistance and excessive grip. Claimed weight is 275-280g, 700×30 solely.
Vector R SW 30 T2 & 35
These have a 120tpi casing and thicker tread caps for longer tread life and a bit extra puncture safety, however are in any other case the identical. Is available in 700×30 (325g) and 700×35 (365g) sizes.
