Bontrager's New Made-in-USA Carbon Wheels - First Ride

Apr 14, 2016

Bontrager XXX wheels


There was a time when carbon mountain bike wheels were the sole domain of the cross-country crowd, a place where the narrow and often delicate hoops were less likely to be hucked into rock gardens or repeatedly slapped into corners. That's no longer the case, and the last few years have seen a massive influx of wider-rimmed carbon wheels hit the market that are aimed at the all-mountain crowd. Not one to sit idly by the sidelines, Bontrager is joining in with their new Line XXX wheelset that's built to withstand the punishments doled out by professional enduro racers and weekend warriors alike. With an an internal rim width of 29mm, the wheels hit that wide-but-not-too-wide sweet spot that allows for 2.3” tires to be run without negatively affecting the tire profile, and for even wider tires to easily be mounted up as well.
Line XXX Details

• Size: 27.5" or 29"
• Intended use: all-mountain, enduro race
• Internal width: 29mm
• Rim material: carbon fiber
• 28 straight pull spokes
• Boost hub spacing
• Weight (29" with TLR rim strips and valves): 1760 grams. Front: 840 grams, Rear: 920 grams
• MSRP: $2,500 USD
www.trekbikes.com / @trek

The carbon rims are made in-house at Bontrager's Waterloo, Wisconsin facility, which is part of the reason the retail price for the set is an eye-watering $2,500. According to Bontrager's Alex Applegate, “Simply put, the Line XXX as it is today would not be as good if made overseas, and we aren’t just saying that, we have tested and proven it. We did not want to compromise with this wheel and the best way to build it was down the hall from where it was designed.”

There are a number of carbon rims on the market that use a hookless rim profile, a design that's easier, and thus less expensive, to manufacture. Bontrager went a slightly different route, creating a tiny hook at the top of each rim that works in conjunction with their TLR plastic rim strips. Once installed, the strips are just about the same width as that tiny hook, and at first glance it makes it appear as if the rims are in fact hookless. Those strips make it easy to set the wheels up tubeless, and there's no need to worry about them ripping or tearing while installing a tire.

When it came time to decide what hubs to lace those carbon rims to, Bontrager chose DT Swiss' ultra-reliable 240s hubs, which use a 54-tooth star ratchet system in the rear hub for a quick 6.6 degrees between engagement points. Both wheels use 28 straight pull spokes that thread into nipples that can be accessed without removing the tire, a feature that's not always present on higher end carbon wheels, even though it should be.

First Impressions

I've only just begun to test the Line XXX wheels, and three rides isn't nearly enough time to comment on durability and strength, but the initial setup was completely hassle-free. I was able to get a set of Bontrager SE5 tires seated and sealed with a regular floor pump, and they popped securely into place right around 40 psi.

At 1760 grams the Line XXX wheelset isn't going to set the hearts of weight weenies aflutter (Bontrager's recently announced 1390 gram Kovee XXX cross-country wheelset takes care of that), but the weight is still very reasonable number, especially if Bontrager's claims of just how tough these rims are prove to be true. I will say that they feel lighter on the trail than the number that shows up on the scale, and even though there was barely a weight difference between the wheels and the alloy wheelset they replaced, I would have sworn they weighed significantly less. There's a very enjoyable snappiness to their handling, with a lively, stiff feeling that doesn't waver no matter how hard they're pushed into tight berms. Cornering was where the wheels' stiffness was the most noticeable - they made the bike feel like it wanted to leap forward, springing out of one corner and then diving into the next with just as much energy.

The big question is, are they worth it? Bontrager have their work cut out for them, especially given the increasing number of less expensive options on the market. The USA-made tag is commendable, and sky high pricing don't seem to have kept other US companies from making their presence known in the carbon wheel world, but it'll really come down to how much of an improvement they make out on the trail. Keep in mind that this is the top tier offering in their carbon wheel line - there are more economical options on the way. Look for a full review one we put more in more hard miles to see exactly what they can handle.

 @fantaman: I ALWAYS say to my friends with carbon fibre* bikes, "Nice plastic bike!" just to irritate them. It is a personality failure of mine that I blame on my parents, my schooling, the state legislature and the fact I grew up on the wrong side of the tracks in a tiny 2500 square-foot house with no running hot and cold maid service.

It could be worse, I might be thinned skinned and have no sense of humor.

 I stopped reading at $2,500. Then came to post a comment, saw yours, and it turned into a reply. A $2,500 wheelset caters only to the ultra rich who don't give a crap about value. At 1,760g it's not hyper-light. the dentists will need to think hard about that next Enve purchase.

 Was what I thought!

I have a set of carbon wheels although in 26" flavour and wonder is there any point as tyre movement does come into play and finding right pressure is nigh on impossible to stop them squirming unless I sacrifice grip.

Needless to say I miss my stans flow exs and that for first couple if rides, they were impressive then forgot they were carbon.

Tyre squirm is my only concern with mine. But then they're only 21/22mm iirc inside bead to bead.

 Here in Europe (Sweden) when you say "Made in the USA" most people don't really think of high quality.. We more think of it as mostly overpriced and often of lesser quality. Now German, Swiss or English made on the other hand!
I think a lot of American brands actually would sell more here if they toned down where it was made and put a few fewer flags on there products.

 @blackthorne: Imply? That's funny, there's actual data that backs it up. And at least when an American car breaks, I don't have to pay a small fortune for parts and labor. At least the "idiots" at GM and Ford have figured out how to make a direct injection engine that won't build up carbon, or an aluminum block that won't score after 50k miles. And then there's the ridiculously complicated, delicate, and oh, expensive to fix diesel exhaust system (I won't mention the other diesel issue). Having owned all 3 big German luxury brands over the years (yea, I make a decent living, without having to pull teeth or fill fillings), they are just as much shite as a 5 year old Malibou, but just look and drive better. Once the factory or certified warranty is up, beware or trade in.

 Those DTSwiss Straighpull hubs are pretty light, how does a carbon wheelset weigh 1760 grams? I have a pair of fortune cookie rims laced to a pair of boat anchor hubs with an internal width of 35mm, and they weight 1742. I am not a weight weenie, just not sure where they are packing on the grams, is it that rubber rim strip? Do the spokes use washers?
  • + 7
 The TLR rim strips add around 100 grams to the total weight. Claimed weight for the rim alone is 435 grams.
  • + 54
 If you can't make $2500 carbon wheels that are lighter than a good set of aluminum wheels, then you need to put down the pipe and go back to the drawing board. These are just stupid.

 I would rather lay off the fried chicken and pizzas for a few months, saving myself more £ and losing more weight than I would if I just bought a lighter wheel set.

  • + 2
 @SlodownU: these are super high end and the goal wasn't only lightweight. The Kovee XXX is the lightweight wheelset and weighs less than 1400 grams for 29er and are also 29mm internal rim width ...2500 completey made at Bontragers Wheel Works with an excellent warranty. DT Swiss XMC spline 1200 wheels are most similar which are also 2500, although not quite as wide.
  • + 2
 Along these lines if you can't make rim strips that are less than a few grams (e.g. 3M strapping tape), then you need to go back to the drawing board.
  • + 1
 Claimed weight is 1535g for 650B and 1625g for 29
  • + 1
 @mikekazimer: still a lot, 440gr rims + dt240 SP +sapims for ex without strip is around 1600gr 30mm internal
  • + 1
 @mikekazimer: @mikekazimer: They should go with the plugs like Specialized with the Traverse Fattie SL's. I think it drops about 80 grams total weight compared to the rim strips. Geesh, my Fattie SL 29's are only 1570grams with the plugs and valves in, and they're 1mm wider, and still have the 54t ratchet, which is awesome, btw. Oh, and they cost $1150 right now. Less than half as much, for wider and lighter, and still with a great warranty.

These will probably be a good deal on some bikes they come on though. Trek stuff always seems to be overpriced when it's sold individually. Like Trek bikes are priced well, but their frame only prices are ridiculous. I guess it makes it look like you're getting a really sweet deal on a bike when they can say it comes with $2500 wheels...
  • + 1
 @SlodownU: carbon doesn't always mean lighter, it means stiffer and holding a better line with out all the vibration. I get that $2500 is a lot of money but you are also paying for stiffness and longer lasting rims, and dampening, just like a carbon frame vs an aluminum. I have been lucky enough to ride ENVE M70's and since switching i have not destroyed a wheel in 2 years... not even trued a wheel and im a fat 200 guy who loves to take the nastiest line i can handle. Worth the 2500? probably not but just like everything else in this industry, someone will buy them...
  • + 12
 Lets put this into perspective. A top of the line full suspension carbon fiber Enduro frame costs pretty much what these wheels cost.
I guarantee you my homebuilt Nextie Wildcats on Chris King hubs are every bit the equal or better of these wheels. They cost me over $1,000 less.

OK. So they aren't made in Wisconsin, USA. Ironically the CEO of the corporation making them in USA (Trek) is firmly behind and endorses all the hostile regulations and liberal policies that create the sad situation that pushes all the manufacturers overseas to make anything cost competitive.

So-FU Trek/ Bontrager. Don't try and play the made in USA card when your CEO is at least partially behind the entire sad state of USA manufacturing.
  • + 11
 It's even sillier if you look at industry 9 wheels. Made in USA, 100grams lighter, and under a grand. I've been beating the shit out of mine for thousands of miles, still straight as an arrow, and if they ever do get tweaked, I can throw them in the trash, but a new set and still save enough money over the Bontragers to buy a new drivetrain.

  • + 2
 @WAKIdesigns: I thought the same as well, but I've seen more broken teeth on the 18t. I think it might have more to do with how much you have to wind up the hub before it engages. On the 18t the gap is more and the wind up is as well, so there is likely more stress on the teeth when they finally engage.

 Hmm, they have some carbon 27.5 40mm rims on their site for much less than $2500 a pair. Why do they have those?

 Weight is not the reason why you buy carbon wheels. It has to do with the rim stiffness/deflection under torque. Ride some carbon hoops, then say carbon isn't worth it.
