At 67g front and 70g rear, the included Bontrager skewers are not going to win any weight weenies battle anytime soon, yet they are very comfortable in hand with a smooth and sure-footed cam action that's close to the venerable Shimano Dura-Ace offering. Photo: Stephen Lam/element.ly

Let me make this clear: I did not expect myself to like tubeless road tires. My tubulars work just fine.

Plus, I have plenty of spare tubulars (intentionally) aging in my garage waiting for their turns.

Unfortunately, their call-ups might take longer now that I find myself enjoying, well, smitten over these Bontrager Aeolus 3 TLR D3 carbon clinchers that we’ve been playing with this past year.

But my love for tubeless road tires didn’t begin this way. In fact, it was like that very first shitty first date.

When the box showed up this past spring, I was as excited as kids running to their gifts under the Christmas tree on Christmas day. Coming in at 1,439 grams  (644front/795rear) with the tubeless strip pre-installed and with the tire valves, skewers, and brake pads included, the Aeolus 3 was ready to rock straight out of the box. A bit of elbow grease and voila, got some 26mm Bontrager R3 Hard-Case Lite TLR tubeless tires installed and off we went.

Then I got a flat on the first ride. Boo.

A 2mm cut from a piece of glass went through the tread and I had just enough air to limp back home thanks to a can of Vittoria Pitstop and pumping more air whenever I could.

It wasn’t pretty and the cleanup aftermath was a pain. Nevertheless, I was able to ride home instead of walking home.

Frustrated but undeterred, I repaired the tire following instructions from Stan’s NoTubes and the tire worked like a charm. When I finally replaced the tires about 10 months later with Schwalbe Pro One , the tires had three major repairs and a handful of cuts that would normally spell the end of a clincher tire. But each time I was able to ride home without having to put in a tube (still have to pack a tube and repair kit with tubeless). And in a few instances, I didn’t even know I punctured until I stopped for my mid-ride coffee.

They have won me over since then and they’re now my go-to wheels. Yes, I reckon my tubulars are still lighter and arguably smoother, but I did find the extra peace of mind and the convenience of road tubeless tires pretty hard to beat. I can pick and choose my tires for the ride/weather without worrying about gluing in advance.

But what about the rest of the wheel? Well, one year of abuse did not do anything to the DT-Swiss internals. They’re still smooth and quiet while the wheels remained true the entire time. The 35mm tall OCLV carbon rim also proved to be durable and comfortable throughout the test. One word of caution: the rims on the Aeolus 3 are significantly wider, measuring at 27mm on the outside with a 19.5 mm inner diameter, so make sure your bike has adequate clearance.

In the crosswind, the Aeolus 3 TLR D3 was easy to handle due to its lower rim height and rim shape, but my oh my, these wheels felt just as fast as some of the taller-rim hoops I’ve been on. Regarding the braking department, Bontrager recommends using their own cork brake pad with the wheels. While cork might lack absolute immediate stopping power, it makes up for its shortcoming by providing a very consistent and manageable lever feel that’s not so bad after getting used to it.

I also love the Aeolus’ overall minimalistic graphics. Big enough to show its maker yet not overly obnoxious as if I was a rolling billboard. And for those that want even more stealth, rejoice my friend, the decals on the rims can be easily removed since they are not water transferred decals with a clear coat on top.

If there’s any cleft with the Aeolus 3 TLR, it would be its $2,400 price tag. Pricey, yes, but a worthy prime candidate for those who are looking for those holy grail hoops for both training and racing with the added benefit of being tubeless. This is a set of hoops that could go fast without beating up the rider. I am addicted.


No Room for a Compressor? Bontrager TLR Flash Charger Floor Pump Has You Covered

For the longest time, owning any tubeless tire almost meant you’d be better off owning a compressor too in order to help it seat properly. A regular floor pump/co2 sometimes worked but a compressor gives you that massive volume of compressed air with just a squeeze of the nozzle lever.

I reluctantly got a small Craftsman compressor when I converted my mountain bikes to tubeless. I found the compressor to be awfully loud as if I was mowing the lawn inside my garage. Good headphones helped but that’s just not very ideal … Can you imagine what it’d be like having a compressor in your two bedroom Brooklyn apartment with squeaky wooden floors? Yeah, not a good idea.

But the Bontrager TLR Flash Charger could very well replace the need for a compressor.

Just Flip the Switch

Built with two chambers, the TLR Flash Charger is part pump, part (manual) compressor. After flipping the unmistakable red switch, you pump air into the giant chamber. To use the stored air to seat a tubeless tire, all you’ll have to do is flip the switch and watch the air blast into the tire.

It’s that simple.

It takes about 42 strokes to get the chamber charged to the red indicator. Which, at about 160psi, was plenty enough to seat our 26, 29, and 700c tires with extra.

Pump it Up … Eventually

The other function of the pump is, well, to inflate your tires. Here I feel the TLR Flash Charger comes up a bit short. It’s not that it doesn’t fill the tires with air just like every other pump. But instead of just connecting it to the tire and pumping away, the TLR Flash Charger needs to be equalized (with the tire) first before one can start the actual inflation (Huh?).

Think of it this way, say the tire already has 100PSI and you want to check the pressure. The pump will pull about 50 psi from the tire for the equalization to happen. It’s not a big deal if the tire is flat as a pancake, but it was annoying having the need to do the extra work. So plan ahead if you’re in a time crunch.

I would also love to see a more precise pressure gauge. The numbers on the existing top-mount (thank you) gauge were easy to read. But I was left scratching my head at the fact that it only showed increments every 20psi with no markers in between (other than 30PSI). So what if I wanted to pump it to 90PSI? Doesn’t that defeat the purpose of having a built-in bleed value?

This won’t be an issue if you measure your tire pressure in bars instead of psi but come on, for $120 you would think that’s a no brainer.

So Close

So is this pump for you? That depends. The TLR Flash Charger works beautifully in setting up all sorts of tubeless. It’s as good as any compressor in that regard albeit without all the noise and need for electricity — which is great if you’re living in a place with sensitive neighbors/housemates/kids, or don’t have the room for an electric compressor.

I really liked the concept, and it would be perfect to the be only pump you should own if Trek can do away with the air equalization.


Bontrager’s New Shoe Game Is on Point

First Bontrager brought their high-end road helmet game into play with any other helmet on the market with the Velocis and now they have landed a set of kicks worthy of shoe lust.

The XXX, XXX LE and even the Velocis are all a step in the right direction for Bontrager.

I unboxed a pair of the crispy white XXX beauties, mounted up a set of cleats with the help of my fit-wise friend, spun up the Boa dials and ran out the door for a 85 kilometer ride in the the hills of Chianti.

The fit is excellent and the Clarino microfiber upper is a beautiful mix between suppleness and toughness to make the kicks comfortable and scuff resistant.

These are not exactly designed to be cozy, but I found them to be reasonably comfortable, with excellent stiffness brought by the carbon sole.

It needs to be pointed out how many of my riding partners were jealous of my new shoes and somewhat surprised they were from Bontrager.

Bontrager is dialing in their high-end game one category at a time and we can’t wait to see where they go next.
