SRAM’s Roam mountain bike wheels have developed over the past few years into a value-packed line up offering a balance of light weight, stiffness, and durability that has given them traction for both aggressive cross country and trail riding. Now with new Roam 50 Carbon wheels, SRAM is bringing top-level carbon tech down by more than 30% in price so more regular mountain bikers can afford the benefits of riding wider-profile hookless carbon rims. Trail riding versatility has been the hallmark of the Roam line-up, and now their carbon offerings will be within reach for more riders…

SRAM calls the new Roam 50 their ‘everyday carbon champ’, and really sees them as the first chance to offer an all-around carbon 29er trail riding wheelset that more mountain bikers can actually afford. The heart of the wheels is the new asymmetric hookless bead, tubeless rim profile. It gets a 25mm internal width, 30.6mm external, and a smoothly rounded shape 25mm deep overall. Those matte UD carbon rims are laced up with 24 bladed, double-butted spokes 2x front & rear with external alloy nipples.

Built around the same fast engaging 52-point Double Time hubs, tool free & symmetric axle endcaps (Side Swap), and asymmetric rim shape & lacing that means one spoke length for the entire wheelset (Solo Spoke) as the Roam 60s, the new wheels offer top performance at more affordable pricing. SRAM also includes six different color sticker packs with the wheels so you can get all matchy-matchy with your bike’s color scheme: red, blue, green, yellow, orange, & red-orange.

The wheels are available in Boost or standard spacing for thru-axles or QRs, and with either their own XD driver or a Shimano cassette body.

The Roam 50 Carbons are actually a surprising deal when you look at the numbers. Available only in a 29er option (the carbon Roam 60 is exclusively 27.5 and will remain the only carbon option for the smaller wheels and their more aggressive riding style for the time being), the wheels claim weights of 765g/890g front & rear for a total wheelset weight of 1655g. That makes them an all-purpose XC & trail mountain bike wheelset, and SRAM recommends them for a max 140mm travel bike to stay within that style of riding. But still, that’s only a 30g penalty over the smaller diameter Roam 60s (with the same internal width) that targets a bit more of the longer travel riding that the 27.5 wheel tends to move towards.

At the same time as coming down in weight, their price drops to $600/$700 (€653€/€763 &  £554/£646) for the front/rear wheels which are sold independently. That’s more than 30% less than the $900/$1000 list price for the Roam 60s introduced last winter. From a value perspective these 29er-only wheels look like a big improvement for the average mountain biker.

Sure $1300 for a wheelset isn’t cheap, but it looks like only about $300 premium over the current previous generation aluminum Roam 50 wheels. If your budget isn’t quite there yet, the alloy Roam 50s look like they will carry over will not continue on in the 2017 lineup, so act fast to pick up those still available from current stock in 26″, 27.5″ & 29″ varieties with their 21mm internal rim width, a bit lighter weights than the carbon wheels, but a drop in stiffness.

But if you are looking for a new set of responsive 29er wheels, the new Roam 50 Carbons look like one of the best values we’ve seen from any of the big companies for everyday carbon trail riding wheels, and are designed and manufactured entirely in-house by SRAM. In time to get you riding soon, the new wheels are apparently already available through your local shop & regular distribution chains now that they have been officially announced.

Sorry but $1300 for a incredibly porky 1700 grams wheel set (where are the carbon savings?) that has a “fork travel” limit at 140 mm (? travel limit ?) is not a great deal.

the fork travel limit seems like bs, and 1655gr is indeed quite heavy.
for good hubs though, 1300usd isn’t that bad.
I built slightly “better” chinese wheels for *more* (asymmetric, bladed spokes, 24mm inner dt240s, 1450gr, 1400USD! basically good hubs aren’t cheap as these would be 700USD otherwise with novatechs)

I’m okay with ~1700g, but not at that price. At that weight, I can get DT Swiss 350 hubs and 32 spokes on wider rims for $800. The Roam 50 does not represent good value for me.

This is great to see – I’ve got a set of Chinese carbon wheels I built 3-4 years ago that have handled thousands of miles of riding. With the huge increase in carbon manufacturing, there is no need for a basic set of rims to cost $2-3K. All the best to Envy (and SRAM’s Zipp), I’ve got nothing against high-end kit, but costs should be coming down on this stuff and I’m happy to see SRAM pricing accordingly.

As a dedicated singlespeed mtb’r, am I wrong to think most asymmetrical rims are too asymmetrical for my needs? I’m an artist, not a mathematician, so please overlook my ignorance in this matter. In my mind, asymmetrical rims are designed with large cassettes in mind, which would overcompensate in my situation where only a tiny dish is needed, therefore negating any advantage to SS riders using SS specific hubs. If there were front/rear specific rims where the front was less asymmetrical to only compensate for the rotor vs the rear and its cassette, I could wrap my simple mind around it better and would get two “front” rims to better fit my SS specific rear hub.

If you are building on a SS hub that has no dish you do not want a Asymmetrical rim. However if you are running a standard wheel with spacers and only one cog you still need an asymmetrical rim. it’s not about the sized of the cassette but how far the cassette body pushes in the Driveside flange. If the wheel has dish it will benefit from a asymmetrical rim. Even front disc hubs have dish which is why they also benefit from asym rims.

I’m following you. But if there is no front/rear specific asym rim, then the asymmetries (?) would be the same. Why is that if the front is only compensating for the rotor, yet the back is having to compensate way more for a cassette? One would think if these specifics matter, the same rim would not work for both front and rear applications.

Subtract the amount it has to compensate for the rotor from the amount it has to compensate for the cassette (it’s about half the distance and the rear has a cassette and a rotor). The rim is flipped the opposite direction front and rear but it does even out for the most part

If a company wanted to have a front and rear specific Asym rims they could, If you offset the rear rim to the point of zero dish then used it on a front build it would create a reversed dish wheel. What most companies do is offset the rim for the front hub to get zero dish then use it in the rear to improve the tension balance but it won’t take it to zero dish. This allows them to only make one rim and still make a better wheel.

Thank you both, Pro Bike Supply and aeroking, I appreciate the time and explanation. I have a better idea now having the flipped front information…helps it click at least.

It’s worth pointing out that you can only get away with a certain amount of nipple bed offset before other compromises set in. Even back when everything was rim brake and the front rims were all symmetric, rear rims never tried to go dishless. They just aimed for reducing the dish as much as was reasonable.

I love carbon for everything other than rims. Carbon rims in my experience crack far too easily. I’ve run carbon rims just as heavy as alloy too. I’ll admit, carbon rims ride awesome. Better in every way over alloy, but durability is a deal breaker for me. I know plenty of people don’t experience durability issues. I wish I was one of them. Funny because I’ve never cracked any carbon component other than rims.

I owned the rise 60. Nice light wheels but too narrow and flexible. These will be the same under its intended application.
