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.

Review: 2013 Reynolds 46 Clincher

December 2013 - I have always stuck to rims with aluminum brake surfaces as they allow me to brake as I please and as hard as I please without much thought about delamination or warping. Indeed, the internet is filled with such horror stories due to failures related to brake surface overheating.


This was until I test rode a friend’s generic 50mm carbon hoops.  I was immediately blown away by the weight... or rather, the lack of it.  After rolling on 1700 gram Shimano C50’s for the better part of the last year, riding on sub 1500 gram wheels was difference as distinguishable as night and day.  


Hill climbing became less of a chore and we went through said uphills a tad faster than normal.


That said, I still hesitated on getting a set. What if it rained? Carbon wheels are notoriously poor in stopping in the wet. What about long descents where you had to sustain constant brake pressure?  Conditions which are reported to be the cause of warping?


Pass.


One day, on a random visit to my favorite brick and mortar LBS, the Godmother herself saw me looking at some carbon hoops and gave me an offer I can’t refuse.


I went home with a pair of 11-speed compatible 2013 Reynolds 46C's.






As much as I hate to admit it, I was pretty excited to leave my alloy brake surface comfort zone and put on new wheelsets. I suppose any Cyclist would feel as giddy whenever such a new equipment scenario presented itself.


On a side note, I would have gone for a more popular and affordable offering from the Reynolds stable, but to be frank, I didn’t quite warm up the graphics on the 2013 Assaults. But subdued graphics, DT hubs and better spokes were enough, in my mind, to pay extra for the 46 C’s.  


Tech


Sporting a more traditional 21mm width and regular V-shaped cross section. The 46C does not sport the now de rigeur toroidal shape nor the 23+ mm width of its newer competitors. Be that as it may, doing so has made the 46C’s innately light without delving into exotic carbon layup territory. And for more than a few cyclists, light weight is an advantage in itself. Although based on what we would now call old tech, the 46C is not without its own aero tricks. Reynolds have incorporated their SLG (Swirl Lip Generator) technology to the inner edge of the rims. This, Reynolds claim, reduces drag on the 46C by approximately 20% at 10 deg yaw,  


The wheels came in at a listed 1440 grams, roughly the equivalent of the Shimano WH-9000-C24’s we’re so fond of. But of course the 46Cs come in a more aero-friendly 46mm depth profile. As an aero road frame user, it makes perfect sense to mount aero wheels to match. The 46C's Simple, smart graphics is always a welcome bonus.  





To address the extended braking scenarios, Reynolds integrated their CTg braking system in the 46 C. The CTg (Cryogenic Glass Transition) System is Reynolds’ patented rim-pad pairing that enables so equipped Reynolds wheels to run up to 53% cooler compared to standard carbon-pad combinations’. In effect, CTg uses different kinds of carbon laminates to transition from the brake surface to the rim itself. This creates a heat sink effect wherein the brake surface passes heat onto other areas on the rim surface where passing airflow helps dissipate the it.  


This ensures smooth and predictable braking performance and dependability. As a system, users are required to use the included Cryo Blue pads else the warranty is void.


Handling mechanical duties are DT Swiss straight pull hubs. Spokes are DT Swiss Aerolites. The front is laced radially with 20 spokes while the rear has 24 in two-cross config. This configuration, like it or not, utilizes internal nipples. While we are sure this aids with smoother airflow, it’s certain to turn some off from doing frequent DIY truing.  


For 2014, reynolds have replaced the 46 C with the 46 Aero model. This updated wheelset sports a whopping 26.2mm width with aerodynamic features similar to the current 58 Aero. Weight has grown to 1505 grams though. 

All in all we were very satisfied with the 46c's.  


On the Road


The first thing we noticed about the 46's other than weight is the stiffness.  The wheels give the impression of immediately transmitting pedal input to the road where it belongs. Spinning these wheels up from a standstill is very very easily accomplished. At speed, the wheels hold speed quite well.


We used the 46C’s with our favorite 25mm GP 4000s’ without a problem. Although this produced a pronounced ‘lightbulb effect’, we felt the immediate benefit of a smoother ride due to the reduced air pressure possible with 25mm tires.


The DT Swiss hubs are smooth and quiet. Perhaps too quiet as we frequently had to call the attention of pedestrians and fellow cyclists as we went freewheeling.


We had the chance to test braking performance on a winding 8km descent from Bugarin. We have to admit that carbon braking takes some getting used to in terms of technique. However, the change is not that far off from alloy as it involves anticipation, timely deceleration and alternating between front and rear brakes. We do miss the ability to gun the brake levers all the way down though.


Unfortunately (or perhaps fortunately) I was not able to test the brakes in the wet. Though it’s something one should prepare for, it’s not something I’m looking forward to personally.



Verdict


Not the most modern of carbon clinchers but still plenty light and stiff. A great value if you get it at a discount!
