Tubeless tires are great and all but I absolutely loathe dealing with solidified sealant every so often.
Even worse, solidified sealant inside tubulars.
Alas, Finish Line have developed a solution: A sealant that won’t curdle inside the tire on its own (duh.)
Developed in conjunction with industrial sealant specialist Multi Seal, the latex and ammonia-free sealant features a DuPont FiberLink Kevlar fiber filler in a liquid suspension that automatically clings to the side of the puncture area to form a physical plug.
Since FiberLink is the part that stops the leak and the fluid in the sealant is merely a carrier, Finish Line is able to design the liquid suspension in such that the liquid will stay in its form throughout the life of the tire. Goodbye dried out sealant.
The non-toxic, hypoallergenic formula is also said to work nicely with carbon rims, is CO2 friendly and water washable. It sure sounds really good and could possibly be a game changer, so stay tuned for our review.
Four sizes will be available: 4-ounce ($8.99), 8-ounce ($14.99 ), 1-liter ($35.99), as well as a monstrous 1-gallon ($139.99) for shops, or anyone who just has a lot of tires.

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.

We had a glitch on the site in the days after InterBike, so this post is way past due but the unplanned slow down also meant more time to relive this year’s InterBike
While the gallery above is going to highlight all the fun stuff… Below are the observations from the show floor.
– First, the appointments. I got smart this year and did a bunch of appointments in advance to check out offerings from various brands. So my InterBike was more structured, with shots of adrenaline from random drive-bys to booths I didn’t know much about.
– The buzz I kept hearing was “it’s pretty quiet this year.” Well, that was true. The show was smaller than last year’s. I honestly could have just spent a day there. One industry veteran commented on how he/she was checking out people’s badges and noticed there weren’t as many buyers at the show as there used to be, and he/she would be pretty pissed if they got a booth… All about the ROI, guys.
– On the outskirts of the show floor was arguably where the fun was… I got a pitch about a solar USB charger stating “looks like you can use one of those” during day one. At the other end of the hall was also a booth that sells handheld electric massage devices. The massage device booth definitely saw an uptake in traffic on Thursday, possibly due to the walking from day one on the floor + CrossVegas hangover collab.
Really thought the days of scantily-clad booth women were a thing of past. But I was wrong. I mean, okay, sex (allegedly) sells. But wouldn’t money be better spent on making a better product instead of having models promoting shitty products (and offending the female attendees while at it)?
Amount of broken arms/legs: It dawned on me during day two that there were quite a few people in slings/braces. Guess adventure shows must have a few of those around. As one rep put it “they’re getting after it”.
Reception of e-Bike: Last year was all about e-bike bashing and all of a sudden e-bikes are the future this year.
The international aisle. Probably the quieter, less buzz sections but everyone there was pretty cool to talk to (knowing Mandarin and Cantonese definitely helped) and they really deserve more recognition for their efforts of travelling across the globe to Las Vegas to showcase their products, whether it’s the gazillion lights, matte carbon fiber parts, or aluminum parts in all the imaginable anodized colors one can possibly dream of.
Best snack from the show: Vanilla Ice Cream at the Skratch booth made with their new recovery drink mix. Not only was the line 4,000 times shorter than the Starbucks line outside but it was also freaking delicious. Way different than the typical “come by our booth for free booze” hook too.
Last thing I did at the show: tried an e-bike at the rep’s prudent suggestion, only to make it 30 plus feet before a security guard rolled up and warned “no biking on the show floor”. Returned the bike to the booth, walked down the aisle, and was greeted by two bros zipping past on motorized scooters.

Flip the red lever down to charge the chamber for tubeless. Flip it again to release the air, or use it just as a normal pump.

The pump head is plastic but it worked liked a champ during out test, gripping both schrader and presta value with ease.

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 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.
