We are pleased to announce the all new Altamont wheel set to the Boyd cycling lineup. Altamont is the road that goes up and over Paris Mountain in Greenville, SC, site of the decisive moments of the US Professional National championships from 2006-2012. Paris Mountain and Altamont Rd are nationally recognized as staples of US cycling. It’s also where almost all on-the-road product testing for Boyd Cycling is performed, both going up and down the hills.

Altamont translates into “High Mountain” and this is where the wheel set really shines. The light weight, stiffness, and stability help when climbing and out of the saddle. The wider rim profile helps the tire to take on a great shape, perfect for flying down twisty descents. The top of the line aerodynamics mean that on the flat terrain between the high mountains no energy is wasted pushing the wheels through the air resistance. This is a wheel set that performs in all conditions; we like to say there is never a bad time to ride it.

 

Thanks to Bike Rumor for helping us debut this new wheel set and giving the first impressions. We are excited to release what we think will be the nicest alloy wheelset on the market.

Building on the success of the popular Vitesse wheel set with a wider rim profile, the Altamont rim is 24mm wide with an internal diameter of 18.3mm. This wider rim profile allows for the tire to take on a great shape, not having to bend back as far to fit into the hook of the rim bed. For flying down hills, through switchbacks, or around corners in a criterium, this tire profile will give you an advantage with better handling. The air volume inside the tire is also increased as the sidewalls don’t have to bend back as far to fit into the rim. More air volume means you can run a little less tire pressure which is great for vibration dampening. It’s also easier to run a 25mm tire for even better vibration dampening and handling, especially for larger riders.

The aerodynamic factor increases as the air flow over the tire onto the rim is much improved. To go along with the improved air flow the transition from the brake track to the side of the rim is seamless. The rim was designed so when the brake track was machined down it’s the same width as the sides of the rim. Better air flow means better aerodynamics and a faster wheel.

The depth of this new rim is 30mm. The deeper rim profile also helps with aerodynamics and wheel stiffness. This 24mm wide and 30mm deep rim makes for a wheel that wants to help push you along. To help with rim weight savings and also keep the strength and stiffness qualities, we have taken a unique approach and ribbed the inner walls of this rim. By adding ribs to the inner walls we are able to shave weight to the rim (475 grams) without any sacrifice to strength and stiffness.

Logos on the rim are laser etched to give a cool metallic off-white appearance. This saves weight and makes for keeping the rims easy to clean, without worrying about any decals lifting or peeling.

hubs-header.jpg

In part of making a complete wheel system, we wanted to have the highest quality hubs come standard on the wheels. We have a CNC factory produce the hubs for us to our specification to ensure you will have the stiffest, most stable, and best engaging hubs on the market.
Hubs can be one of the best ways to increase the stiffness of the wheels. If you think of a wheel as a triangle instead of a circle, the spokes have a base at the hub and come to a point at the rim. By increasing the base of this triangle you are making for a sturdier object, which translates directly to a stiffer wheel. Our hubs have some of the widest flange spacing on the market, which combined with the strength of the rims help to make for incredibly well responding and stiff wheels.
Hub stability is something that is often times overlooked, but can be felt immediately when standing (such as when sprinting or climbing). To accomplish higher stability the bearings were also moved out as far as possible on the axle. Many hubs have a long end cap on the non-drive side with the bearing quite far from the edge of the hub. By supporting the non-drive side bearing and moving it out to the edge of the axle, the wheels stability is greatly increased.

**IMPORTANT**    For freehub body choice on Shimano, if you are planning on getting 11 speed Shimano the next year then choose the 11 speed option. You will have to run a 1.8mm spacer behind your cassette while you still have 10 speed, but when you do make the transition to 11 speed you can just slide on the cassette with no new parts needed or any re-dishing of the wheel needed. If you are planning on running 10 speed for a while, choose the 10 speed option. You will have a rear wheel with the right flange pushed out farther to make it stiffer and with better tension balance between the drive and non-drive sides. To upgrade down the line to 11 speed you will need a conversion kit which will consists of a new axle and a new freehub body. A slight re-dish of the rear wheel will be needed when moving from Shimano 10sp to Shimano 11sp.

 

spokes-header.jpg

We still feature Sapim CX Ray spokes and Sapim SecureLock brass nipples on all carbon builds. Spokes are laced radially on the front and double crossed on both sides of the rear wheel for a stronger build and much better transfer of torque. All spokes and nipples are black. Ghosted decals will come standard on all carbon wheels in 2013 for a very stealthy look. The decals will be under the clearcoat for better durability and prevention of any lifting or peeling. This helps keep your wheels looking newer for longer and makes them easy to clean. There will still be two spoke count options for the 44mm clincher. This allows us to make the strongest and most durable wheel set.

A radial spoke cannot transfer torque from the hub to the rim. On a regular front wheel, it’s sort of along for the ride, so radial laced spokes are fine for a front wheel. The exception with this being with disc brake hubs where you have negative torque going to the hub when you are braking, which is why on our disc brake hub wheels we double cross the front spokes.

On the rear wheel you are putting a lot of torque to the hub and this has to transfer to the rim to get the wheel to spin. By crossing the spokes on both sides of the wheel, we have up to 15% better torque transfer compared to a wheel that has radially laced spokes on the rear wheel. This makes for a better responding wheel that will accelerate faster, especially in sprinting or climbing situations.

We brought the Altamont to the wind tunnel during product development for wind tunnel testing. Below are the results in comparison to both a Zipp 101 and a Mavic Ksyrium SL wheel set. All data was taken from the website http://www.cyclingpowerlab.com/componentaerodynamics.aspx which compares wind tunnel data from multiple sources to a standard elevation and air density.

 

spoke-count-header.jpg

 

The Altamont will come with 3 different spoke count options to suit any rider. The standard is a 20/24 spoke count, recommended for riders under 180 pounds. The higher spoke count is a 24/28 suited towards riders between 180 and 240 pounds. Finally, we have the overbuilt option, an incredibly strong 28/32 spoke count which is suited for any rider over 220 pounds. There is no weight limit on the overbuilt option, yet the set still comes in the mid 1600 gram range. By offering these three options we can tailor to anybody’s riding style and weight with no sacrifices in terms of quality.

All options will come standard with Sapim CX Ray spokes and the Sapim SecureLock brass nipples, both in black. Lacing pattern is radial on front and 2X on both sides in the back, with the exception of the overbuilt spoke count option which has 2X on the front and 3X on both sides in the rear.

 

build-quality-header.jpg

Obviously a lot of the pervious components are things that CAN make for a good wheel set. However, making sure the build quality is as high as possible is a final huge step. This is why all of our wheels are 100% hand built in-house in our own wheel building facility in Greenville, SC. To ensure the highest possible quality all tools are calibrated multiple times per day to ensure the highest possible consistency.
Each wheel is properly stress relieved multiple times to make sure it won’t ping and pop on those first few rides, and so it stays in true through the break in period as well. The wheels are built from initial tensioning to final touches by the same wheel builder allowing them to work with each small intricacy that a wheel may have. Finally, all our builders only work on our wheels. They know exactly how each one will build up, down to the point of how many turns to put on a nipple to get initial tension. The industry standard is to use high volume assembly factories where each builder is working on dozens of different brands and expected to build between 40-50 wheels per day. Speed is placed at a premium over quality, and in many cases the first 50-90% of the build process is handled by machine.

By placing such an emphasis on quality, and by building in house, we have many layers of QC that are not found elsewhere.  For you, the customer, it means you can always expect the highest quality wheel to be delivered to you whether it’s a carbon or alloy, January or July.

  1. Wide, Stiff and Light

    Posted by Dave Watson on 22nd Apr 2014

    I have put about 400 miles on these and they have not disappointed. The extra width helps with the ride comfort, and handling. The fairly light weight make them a great all around wheelset. Just remember to check your frame before you try to fit 25mm tires, they didn’t fit in my frame. This wheelset is also stiff to help with the power transfer.The customer service that Boyd provided during the delay was top notch. But when I received a phone call form them I was shocked, in a good way.
    Great wheel and customer service will make me a repeat customer.


  2. Altamonts do what they say they do, Period!!!!

    Posted by Gerard Scheer on 21st Apr 2014

    After looking at multiple builders I decided to go with Boyd Cycling's Altamonts for numerous reasons. I have a mix of road conditions as I live in the Bronx in NYC so a good portion of my rides are on questionable surfaces. I went with the 24/28 spoke count and these wheels have not let me down. They have made my SuperSix feel like a new bike. They climb great and on downhills they ride like a dream and hug turns like nothing I have ridden before. When my lbs installed them they were impressed on the build quality when I told them the price. If you are even remotely thinking of these wheelsets give Boyd a call and you will be set.


  3. Sturdy and fast

    Posted by Alex on 7th Mar 2014

    Confidence-inspiring wheelset. Rock-solid, lightweight, handles superbly. Huge upgrade from the stock FSA wheels on my new bike. No flex!


  4. Great wheel set at a good price point

    Posted by Steve haycock on 27th Feb 2014

    I bought these wheels as an upgrade to the stock wheels that came with my 2009 madone. I have 200 miles on them so far. I was not sure if I would notice the difference, I was in for a surprise. First thing I noticed was the lack of wheel flex when I am out of the saddle rocking the bike up the hills, you just feel that all of your energy is going into making the bike move. Have already busted a strava segment on a hill I ride regularly and that was by myself on a cold day. Also notice the aero benefits during spirited group rides, on small roller type hills I can gain speed on the down hill sections and keep it maintained long enough to get me up the other side without loosing too much speed. The wheels look like they are well made, run true, look great on my bike and add a nice lively feel to the bike. Looking forward to riding many more miles when the weather improves.


  5. Great Wheels

    Posted by Brian on 16th Feb 2014

    Found these wheels to be a much less flexy than the Bontrager Race TLR wheelset I had been riding. The additional spokes seems to have resolved that issue, yet, the overall weight is lower for this wheelset.

    Have about 300 miles on them so far and my avg speed has increased about 1 mph on my normal 40K course, but find in general, they spin very well. I also found the mounting and un-mounting of the Vittoria Rubino very easy, which is a plus as I really like these tires.

    While I live a very flat existence in NE Florida, I do like the firm feel of the ride when I have to cross one of the bridges over the river or inter-coastal.

    So far, I am very glad I made the decision to buy these wheels. I will follow up once I have some more time and distance on them.


  6. Love my new Altamonts!

    Posted by Dan Goese on 12th Feb 2014

    I don't have a ton of miles on them yet, but I love my new Altamont alloy clinchers. So far they have performed very well (stayed true, felt good on climbs, descents & sprints). I'll report back if I change my mind, but in the meantime I'm enjoying them. The black finish with laser etched (?) design goes perfectly with my black Colnago with white logos/print. I'm so glad I found these before spending hundreds more on HED or Zipp...the alternatives I was considering. My old Hed Ardennes came out of true on the first ride with them a few years ago, so I'm already happier with these.
