Review: 2014 Reynolds Assault SLG

January 2013 - Fresh off dipping my toes into carbon clincher waters via the Reynolds 46C, I immediately went to look for something more modern. I wanted a wheelset with a toroidal cross section, light weight and the requisite wide track. These wheels need to be priced far enough from Zipp and Enve to make sense not getting the after-mentioned wheels. 

With Reynolds really making a fresh, good impression I didn't hesitate to pull the trigger (or rather push the Buy Now button) on a pair of 2014 Reynolds Assault SLGs. 

Indeed, the spec sheet was impressive. Toroidal - check. Wide - check. Lightweight - check. Affordable - hmmm okay, check. 

A few emails to my USA shipper and a few days later, the Assaults have arrived.





Tech

There is much to like about the 2014 Reynolds Assaults. 

First, the depth. The Assault SLGs come in at a very very sexy 41mm rim depth. I would like to say that for a Roadie like yours truly, this depth is just PERFECT. It looks deep enough to be aero yet thin enough to suggest rapid acceleration. Who would have imagined that just shaving off 5mm from the 2013 Assault depth would make much of a difference. 




Reynolds 46 C and Assault SLG - 46mm and 41mm

Second, the width. At 25mm wide. The assault SLGs give you width and then some. When paired with our staple 25mm GP4000s', we were presented with a very clean tire-rim profile without the lightbulb shape which would have been present in the case of 25mm tires and 21mm> rims. This would surely please a lot of aero geeks (oops....enthusiasts) out there. Aerodynamics aside, we were surprised at how low we went with our air pressure. More on this later.

Third. Weight. Our sample came in exactly at the manufacturer's claimed 1475g (Front: 649g, Rear: 826g - no tape and skewers). The Assault SLGs do not really stand out from the crowd in terms of overall weight. But - the listed weight is not bad at all, given the 25mm width.  




Straight pull hubs are by Reynolds Racing and spokes are DT Swiss Aerocomps. Twenty radial spokes in front and 24 in the rear mounted in a two cross-drive side pattern.

The Cryogenic Glass Transition (CTg) brake surface which is present in our previous 46C clinchers makes is also incorporated into the Assault SLGs. CTg is a series of different compounds and materials which are designed to better withstand the heat produced by braking. And of course, the system requires the use of Reynolds' Cryo Blue pads which are solely to be used with the CTg surface.

Reynold's Swirl Lip Generator (SLG) is also featured in the Assault SLG :). SLG is a very small protrusion on the inner edge of the rim which disrupts passing air enough to replicate the airflow of a wider rim. The effect of which is smoother, and therefore faster, airflow.

Spoke nipples are external; this should please a lot of cyclists who do their own truing.

Graphics are thankfully subdued, with the logos and names printed in thin white outlines.


Veloplugs

This was our first time to try Veloplugs as well. In an effort to keep the set weight below 1.5kg, we used these marvelous contraptions to keep the weight down. And they worked! At an estimated 5g per wheel, we saved somewhere in the region of 30-40 grams compared to the supplied tapes. 

Weight weenies rejoice!

Oh, and just so everyone knows, we used the Red Veloplugs for the Assault SLGs.


My sincerest apologies for using an Instagram pic of the plugs

On the Road


During our first time out with the Assault SLGs, we experienced a very loud squeal coming from the front brakes when applied at medium to high speed. While disconcerting, we easily remedied this by toeing in the pads. Although recommended, this was something we never had to do with the 46Cs. 

Almost Immediately the 25mm width's advantages made itself felt. While we typically run 95/100 PSI front/rear. We purposely pumped in 90/95 during our first ride. It made a bit of a difference. Subtle but noticeable. And after several more rides and a few pounds of rider weight loss, we now run the Assault SLGs with a tire pressure of 75/85. 

The ride at this pressure is simply amazing! 

Acceleration is very good and so is the handling. The stiffness of the 46Cs is still there, but fortunately, much of the bite from road bumps are taken out by the tires. 

One thing that these new aero shapes do well is handle crosswinds. The Assault SLGs are no exception. Although you still feel sudden sideward gusts, they are a lot less noticeably felt and you can easily power through constant sidewinds from 3 o'clock to 9 o'clock.

We really like the Assault SLGs and it seems these will be mounted on roadie for quite a long time. 


Looks perfect on the Foil


Verdict


Equipped with the latest in wheelset tech. Not exactly cheap but the money feels well spent.

    How are these wheels holding up so far? Any issues with the hubs?
    One thing i've not found info about is the lifespan (total distance) of carbon rims. Obviously there are may variables to consider but generally speaking if one was to ride them in ideal conditions and put roughly 6,000 miles/season on them.

    Thanks for the great review by the way.

    I am thankful to you because your article is very helpful for me to carry on with my research in the same area. Your quoted examples are relevant to my research as well.
