Once a high-priced and useful execution concoction, carbon wheels have fast become a mature market with countless innovative and imitator options. Costs are forever coming down, and the onset of disc dampers has all but removed safety concerns over such cheaper alternatives.
Scribe is a relatively young consumer-direct company from the UK that’s following in the successful tyre ways of firebrands such as Hunt and Prime( Wiggle’s in-house firebrand ). Scribe’s founder, Alan Graham, was in fact responsible for Prime rotates over a number of years.
I’ve had Scribe’s popular Aero Wide+ 42 disc brake wheels on test for nearly a year and can report that these are an extremely well-thought-out and high-value option. However, those looking for a quiet ride should wheel straight past these.
The Aero Wide+
Key aspects: Disc-brake-specific 42 mm-deep carbon rim, 30 mm external width, 21 mm internal, hooked rim bed, 54 T spline-drive freehub mechanism, centerlock rotor organizes, Sapim CX-Ray bladed spokes.
Weight: 610 g( breast ), 810 g( rear ), 1,420 g( duet, with tubeless strip)
Price: US $1,000 with free global shipping( local taxes and duties not included)
Highs: Consumer-direct pricing, weight, modern rim thicknes, fixed boundaries work with any clincher and most tubeless tyres, smart-alecky hub blueprint, good stiffness, minimum graphics, magnanimous assurance.
Lows: Freehub noise, tight-fitting rims, uneven spoke pressure on the breast rotation.
Scribe’s new Aero Wide+ motors all share a modernly wide internal diameter for tyre funding and capacity, with an expanded exterior diameter for aerodynamic intents. In the case of the tested Aero Wide+ 42 s, the U-shaped rim offers a 42 mm profundity, a 21 mm internal diameter, and reachings out to 30 mm wide on the outside.
That wide exterior sketch has fast become a common tendency amongst many of the latest aero rims as tyres have become wider. The basic destination now, commonly referred to as the 105% regulation, ought to have the boundary exterior marginally wider than the tyre so that the wheel can control the airflow. In situations of these Scribe motors, the rim extent is aerodynamically at its best when filled with a 25 mm tyre( often closer to 28 -2 9 mm calibrated on these boundaries ).
Interestingly the boundary was still( marginally) wider than the Continental GP5 000 28 mm tyres I installed which quantified an actual 29.3 mm wide at 80 psi.
External rim widths have grown with tyre extents. The Scribe Aero Wide+ rims are far from the widest out there, but the width is enough to sit proud of 25 mm tyres and some( narrower) 28 mm tyres, more.
Scribe is currently in the process of having its 32, 42, 50 and 60 mm depth Aero Wide motors substantiated in a air tunnel( testing was delayed due to the pandemic ), and so the company didn’t have any data ready to share at the time of publishing. And while I’m not in a position to support any of Scribe’s aerodynamic claims or draw comparisons against other aero wheels, I can say that the NAC-Abased rim shape they’re exerting is widely accepted as efficient.
They’re impressively low-pitched in force, more. My sample prepared of 42s weighed 1,420 grams( 1,438 g claimed) with the supplied tubeless videotape. That’s an impressively competitive figure that holds its own against a number of premium motors, and certainly lashes many of the new big-brand value alternatives such as Enve’s 45 Foundation, Zipp’s 303 s or Bontrager’s cheaper Aeolus.
That low-grade load was not possible through the sum of well-weighted percentages, and there’s a surprising quantity of quality now. The speaks are straight-pull Sapim CX-Rays, the same thin aero-bladed spokes you find on numerous ultra-premium carbon pedals( such as Enve’s SES range ), and they’re laced with Sapim alloy teats and rim washers. Meanwhile, the hubs offer a detailed CNC-machined flange design and a surprising freehub mechanism, something I’ll come back to.
The centres furnish an aggressively machined flange designing.
The carbon rims feature a secured tyre beading for use with either clincher( internal tubes) or tubeless rubber, and they’re said to conform to the new ETRTO standards. The wheels well excel ISO fatigue and strong evaluations, and while they aren’t more on the UCI’s approved directory, Scribe is currently patiently waiting for them to be added.
I often get fearful when announcing in smaller- and newer-brand carbon motors for recollect. The sceptic in me often expects the motors are simply something bought from a company like Yishun but with a different sticker. And while some of these products render incredible evaluate for fund, I’d very deplete my term evaluating concoctions from firebrands that have invested in their own research and development.
Speaking with the company’s founder, Alan Graham, these votes in quickly became apparent that there has indeed been great investment put into the creation of these pedals and that they’re not simply another open mould rebrand. And while it’s possible that Scribe is sharing a boundary mould with other firebrands here, the exact specifications are unique to the company.
The build and the hubs
Perhaps most telling of the quality level is a reasonably affecting poise and consistency in addres pressure, and it’s something that has remained that way through my test period. The buttock rotation offerings a 2:1 lacing structure with 24 talks, and impressively there’s a consistent 110 Kgf( approx) of tension from left to right and the whole way around on my sample. This points to the rim being wonderfully round initiated with, and attention to detail in the improve.
Unfortunately, things up front are more variable and less impressive, with talk antagonisms in all the regions of the 21 address fluctuating by up to 15%. And while such variance isn’t ideal, it’s too not all that uncommon( even on some payment wheels ). At least these tensions and the rotation trueness have remained consistent. Of trend, this is all based on a single test, and I don’t have any insight into how consistent or incoherent this is across the rotations sold.
At the centre sit the aluminium-shell hubs which facet centerlock rotor prepares( six-bolt adapters included, too) and sealed births within. Access to those tolerates is simply achieved by plucking off the press-fit end caps on the figurehead, or with a couple of cone strains for the rear.
Open up the rear hub, slither out the dark-green anodised aluminium freehub body and you’ll be accosted with a ratchet ring-style drive plan. This system is extremely same to DT Swiss’ new( and premium-priced) EXP centre plan, but while the Swiss company use a ringlet spring to push its single moving ratchet echoing against the set caste sound, Scribe’s design expends a weary leaf spring.
Scribe currently has an exclusive license for this system, one which provides for a speedy 54 stations of commitment and is extremely easy opening hours for cleaning and regreasing.
Some earlier reports of Scribe motors complained about the aluminium feehub bodies being soft to cassette digging, but that has now been rectified. My sample peculiarities a small metal bite guard insert on the Shimano freehub that will prevent any major chewing from becoming an issue long-term.
There’s a bite guard to stop cassette cogs from burrowing late into the freehub. It doesn’t altogether stop the cogs from excavating, but it will foreclose that digging from breaking the freehub.
Like countless centres, there are currently four sealed permits in the rear hub, and two in the front. Scribe offers a alternative between “Endurance” or “Race” endures, with the onetime render better closing and thicker grease, while the latter being EZO bears with a lighter grease. I opted for the latter and my test pedals are still revolving smoothly, nonetheless, they never certainly verified brutal climate.
Scribe applies the same three-year warranty available to its wheels to the tolerates, too- something that’s rarely seen in the industry. This warranty means they’ll supply you with up to two rectifies of replacing bears over the first three years of wheel ownership, nonetheless, you’ll still need a behavior to have them installed. A modest tangent on the topic of warranties: Scribe also provides a lifetime crash replacement warranty for its carbon motors. If you get caught in a wreck or slam into a inhibit then Scribe will change all the damaged factors without charge; the only expense will be paying for the postage to and from Scribe’s UK base. If those carrying costs are prohibitive then Scribe will send out the requirement for responsibilities without charge, and you’ll simply be out of pocket for the regional rebuild.
Five of the six tolerates are relatively easy to supplant with common carrying implements, something an experienced shop mechanic could do without a beading of sweat. Nonetheless, you’ll need a proprietary tool to access the right side bearing in the rear hub husk that obstructs behind the drive sound- thankfully Scribe offers this for a perfectly reasonable US $30.
Much like a DT Swiss hub, a special tool is required to access the producing behind the drive peal.
As with most centres, some simple and semi-regular cleaning of the hub internals will go a very long way to ensuring the abides last. The Scribe hubs seem decent at maintaining impurity on the outside, nonetheless the sealing is still vastly simpler than what something like DT Swiss hubs offer and so you should plan for more regular service intervals.
Beyond the choice in producing type, Scribe also offers freehub forms to suit Shimano, Campagnolo, or SRAM’s XDR. The breast centres can be altered between quick-release, 100 x 12 mm thru-axle and 100 x 15 mm thru-axle. The buttock hub occur within 142 x 12 mm thru-axle or 135 mm quick-release.
Riding and things that are important
Scribe sends its pedals in a single box with a handful of useful adds-on. There’s tubeless tape wrapping the motors( although it did bubble after a few months of sealant show ), alloy tubeless valves are plied, as are a few spare spokes and teats. There’s the rotor adapters and centerlock lockrings, extremely. Eventually, a spacer is provided for those wanting to run 8-, 9- or 10 -speed cassettes on the 11 -speed freehub.
Scribe adds a small handful of segments with its rotates. Those centerlock to six-bolt adapters are pretty weighty for a wheel like this, but they do work.
Getting tyres on the Scribe motors proved a bit of a struggle, and the boundary certainly supports a fit that’s on the tighter discontinue of the spectrum. This was most obvious in preparing for the recent Field Test where I lay 28 mm Continental GP5 000 clinchers on a handful of different pedals. The Scribes were certainly the tightest-fitting of the small sample group and had me reaching for a tyre bar to pop them into place.
The rim doesn’t have the deepest of centre channels and so I ascertained attaching tyres to be a bit of a challenge.
With the tyres in place, there’s a reassuring bead daddy as the tyres seat in place. This is something I truly regarded when flowing road tubeless( Goodyear Eagle F1 ), and inflating such a setup was easy.
There were three things that were immediately pronounced when razzing these rotations.
Firstly, there wasn’t a single pop or crying resound of talks sitting into sit, proving that these wheels were pre-stressed and pre-tensioned properly at the factory. In fact, Graham says the rotations “re going through” two rounds of pre-stressing during the assembly.
Secondly, there’s an immediate impression of positive system stiffness and security. There’s no annoying hub flex generating rubbing of the disc brakes when leaning the bicycle over or sprinting. There’s no abiding play at the hubs. And there’s a good direct feeling to the boundaries, more. Jump on the pedals and these motors react as you expect them to.
And thirdly, these rotations really feel like a high-end hastening motor. That low-spirited heavines rotates up quickly and there really isn’t much to tell these apart from far more expensive hoops. The fairly stable handling in crosswinds is what I’d expect for a wide rim of this penetration, and they seem to hold their raced as well as same mid-depth wheels, very. I won’t pretend to be able to feel whether these reel as efficiently as a Zipp, Roval or Enve formerly at race. I’m not a jazz passageway.
The 42 s are by no means a deep rotation. Scribe offers both 50 and 60 mm breadths for those working wanting more aero operation, and the company has a number of mixed-and-matched mullet-type combos accessible, more.
Wheels of this profundity are my typical advantage for general artery going. They furnish a noticeable aerodynamic advantage over a genuinely shallow wheel while still remaining easy to handle in gusty status. They too render superb stiffness without being bone-jarring, and the lower load keeps them feeling lively. The Scribes tick all of the boxes here.
However, it’s the freehub racket that I found to be even more palpable. The freehub’s leaf spring design seems to keep the ratchet rings in close contact. Add in all of those points of action and this is one boisterou coasting hub formerly at acceleration.
DT Swiss’ new EXP hub is pretty darn noisy as well, but Scribe has it beat in decibels. I’ve been rushing between a assortment of loud hubs lately- the Hunt Sprint hubs, DT Swiss EXP, and Chris King R4 5s on my own personal bike- and the Scribe is the most obnoxiously loud of the lot.
A small sample of freehub noises. Note that some of the rackets overtook the microphone and so the actual loudness is not well reflected here.
On more than one motive I had random cyclists look back to see what was coming up on them. I had one journeying friend ask me to keep pedalling as the sound was driving her nuts. And I can confirm that I find the sound overtaking at times, too.
The rear hub may be noisy but the boundary decals are wonderfully insidious. They’re a liquid decal that can be removed safely with acetone. Scribe now offers black and amber decals, very.
I’ve played a bit with quietening these down, and thankfully the mechanism seems quite tolerant of different greases without any indicate of spline slip. Scribe recommends its “own” MV1 grease, while I spotted a thin grease like Dumonde Tech’s freehub grease to be perfectly fine, extremely. A generous application of grease took the hubs from “ouch, my brain” to “oh, that’s much better but still loud.”
Some parties cherish thunderous centres, and that’s immense. Others wish a gentle or dull interference as they loosen on the pedals, and those people will absolutely not find bliss in these pedals.
These pedals sell for US $1,000 including international ship. Depending on your locale you may be stung with taxes and import obediences, but still, the rate is impressive.
Lower-cost carbon rotations have existed for a number of years, but a wheelset like these Scribes procreates me truly question what a far more expensive wheelset still has to offer. Ok, arrange of producer or at least attention to sustainable manufacturing is one reason to still spend more. Or maybe get a big-name hub knowing that portions will always exist is another reason. But beyond that I certainly start clasping at straws when it is necessary to a wheel for disc damper use.
The tight-fitting boundaries are probably not a good thing for beings with median tyre-fitting technique. That centre interference is going to be extremely polarising. And that variance in the figurehead mouth friction further proves these aren’t perfect. But geez, everything else here is darn impressive when you consider the price. And it’s accurately rotates like this that help to drive down the price of everything else, and that’s a trend I’ve been roused to see over the past couple of years.

It’s this simple leaf spring that keeps the ratchet reverberates in close contact.
