Spēd Precision is one of the more recent brands to jump into the fold of carbon wheels. The company's founder is no rookie to the industry, however, with a background that stems as far back to a time where many of us were more than likely either in nappies or beginning to roll about on training wheels. After some moving about in more recent years, the decision to start a wheel company was taken and they haven’t looked back.
The goal was to create a carbon set of wheels for most dirt disciplines; DH, trail/enduro, XC, and Cyclocross, with a number of slightly different approaches taken in an effort to create something that was durable, rode really well and was still durable. In an effort to maintain better control over the complete wheelset, rather than just a rim, Spēd chose to invest in tooling to manufacturing their own hubs, as well as the carbon rim. They partnered with HT for their spokes.
The brands' more aggressive wheels come with the Maul name and include the Maul DH and the Maul Trail—which they state can do anything up to competitive enduro racing. The rim profile in these wheels is the same, but the layup is different for the DH version in an effort to account for the extra abuse that downhill has on a wheel. On the topic of DH, Harry Molloy’s rider led, FS Patrol Funn World Cup team are on the Spēd wheels for 2017. With the changes to the layup, there is a claimed difference of about 80g between the two Maul rim variations and the full DH wheelset weighs in at a claimed 1,975g while the Trail wheels weigh in at a claimed 1,775g.
Aside from the changes to the rim layup, the only other difference is in the hub spacing options, with the driver and the spokes in each being the same. Both wheelsets are built with 28 straight-pull, HT spokes (while the XC wheels are built with 24 spokes in the front and 28 in the rear) and they include a socketed spoke nipple, which is said to make it easier to build a wheel or replace spokes.
A lot of the quality control on the wheel build comes into play at the spoke interface. Spēd’s rims contain a supported, reinforced nipple support that is directional to match spoke entry, which Spēd claim that along with their own manufactured hub, creates a more controlled wheel build. They mentioned that one reason for this is the nipples fit flush against the rim bed, rather than being pulled to an angle and only having a portion of the nipple contacting the surface, ensuring a better interface.
The rim bed is also a little different too, with the inclusion of a four degree angled tire bed to help with seating the tires, and a bead hook—each, they claim to help with tire security as well. Spēd decided to use a bead hook after seeing elite level riders burping or rolling tires completely off their hookless rims, even going so far as mentioning that some riders may even be using materials such as silicone in hopes of keeping the tires in place. Including the bead hook, the internal width of the Maul’s is 28mm, and 30mm without the hook.
The internal width was a process too and rather than picking a number that seems like it would sell well, Spēd mentioned that they instead worked with tire manufacturers to find an optimal width for competition size tires (2.3"–2.4"). Sample tires were also mounted and tested during the process, allowing the brand to be sure that they seated well to the rim and provided a good profile.
The Maul wheel builds each use the same rear driver, which is a fairly impressive looking unit in and of itself. It contains an oversized race that butts against a large bearing inside the drive-side of the hub. The hub consists of 6 pawls, each double stepped and supported by another good size bearing. The pawls are offset so that three are engaged on 42t drive ring in the hub shell, and create 3.5 degrees of engagement.
The Maul DH wheels retail for $1,900 USD and the Maul Trail retail for $1,750 USD. The Sparth XC wheels are built with all of the same ideas as the Maul, only in a slimmer, lighter package. The driver is more traditional, but said to still be a completely reliable system and includes four pawls and 4.1 degrees of engagement. The rim is a lower profile to save weight and comes in at 1,370g for the 27.5” and 1,420g for the 29. While working with the tire manufacturers on the XC rims a 1.9" wide tire was used and resulted in a 21mm internal width for the rim. These retail for $1,550 USD.
The wheels are available in all of the modern hub offerings and we’ll be putting a set of the Maul Trail wheels to the test in the very near future. For more on the wheels, you can check out

@Jubbylinseed: Aluminium rims are so good nowadays because of the relatively expensive $1000-$1500 aluminium wheelsets of 10 years ago. We all thought those were crazy-expensive then, but they are the reason you can get a $400 alu wheelset now and it's the quality it is.
Hard not to be weight weeny though .
Performance aside, I'd never pay the prices these "high end" wheelsets cost. Get yourself a set of Light Bicycle rims and have some beers afterword! Can't say enough good things about LB.
I'm getting a different number.
6 pawls offset (2 pairs of 3 offset by 1/2 a tooth) effectively doubles the amount of teeth, so that would be 42x2 = 84 teeth. 360 degrees divided by 84 teeth = 4.2857 degrees of engagement (round up to 4.3).
The Maul hub driver looks like it's derived from Novatec technology. The bearing, circlip, pawls, springs, and the piece which they sit in look identical to the Novatec X4 Type cassette body used in the D542SB and XD602SB hubs. Just the flange that sits against the side of the pawls looks a bit different. Not a bad thing at all, just an observation.
3.5 degrees of engagement = 102,85714285714285714285714285714 POE.
Where is the missing 0,14285714285714285714285714285714 POE?
Regardless it is a very precise and nearly bulletproof hub. Very high quality and not that expensive.
In the end I do "just ride my bike"...but when i'm not riding i'm a real gear geek.
We just woke up from a midnight run from Monterey and have some time to answer a few questions while we take a break from unloading the van. Feel free to post a few questions and we will try and get back to some of them over the next few days.
-Why we are doing what we are doing with all the wheels out there..
-What our design philosophy is..
-Questions on shape etc...
We are an open book here and working on getting a world cup level wheelset into your hands at a real world price.
Want our riders and customers to see the engineering they are paying for instead of just taking a brochures word for it.
Look forward to talking to some of you guys(and gals)
Thanks for stopping by..

Or you can spend about 1/3 less and buy yourself a mavic deemax wheelset which weighs 1,965 grams which has an alloy rim and is still somehow lighter and probably better
Absolutely.
Mallets underfoot? Same gentleman.
