Keith Bontrager’s name may not be on production bikes anymore, but that doesn’t mean the folks inside Trek’s Waterloo, Wisconsin, headquarters can’t have a little fun with their project builds now and then. This Bontrager steel disc brake road road bike is thoroughly modern, and one of a kind.

It’s 1x, and pairs a Dura-Ace road crank with an XTR Di2 rear derailleur and cassette.

Thru axles and flat mount brakes, of course.

Ample tire clearance means it could double as a light-duty gravel bike running cyclocross tires. And what about those tires?

They’re 700×28 Bontrager R4 Classics Tubular with a high grip compound. They’re $99.99 each. There’s a 320tpi clincher version, too, if you just want that look, but with a slightly different tread (or lack of) pattern.

Finishing off the build was their 68g full carbon saddle, which is also available for a mere $380.

And now for things that are really new. Earlier this year, they released the top level X X X Aeolus wheels, and we’ve reviewed them here. Now, there’s a more affordable Pro 5 version that comes with many of the same features, with a new 50mm depth. Our man at Bontrager, Alex Applegate, runs through the details real quick and shows off a few other goodies in this video:

Across the range of regular and X X X models, they have depths from 20mm to 90mm, offering something for everyone from climbers to time trialists. The rims are all OCLV carbon, but the highest end models receive a new brake track treatment (among other upgrades).

Bontrager’s Aeolus carbon road rims are tubeless, and you can set them up with regular tubeless tape, but they include their rim strip inserts that make it easier and quicker, but add a few more grams.

Retail is $1,200 for either rim or disc brake sets.

A few other things worth looking at include their Portal road helmet and Rally mountain bike helmets use their Blendr mounts that attach magnetically. Quick, easy integration that’ll break away if you wreck.

Their Velocis road shoe now comes in a bright orange, day-glow orange color to catch drivers’ eyes.

The Flatline MTB shoe gets a new sole and style updates.

Why is there no “overall” photo of the steel bike?

I second this question, showing bits and bobs of the bike is a horrible tease!

Excellent question. That’s four votes, and that means the vote carries. Post pics of the whole bike.

$1200 for a set of tubeless ready CF rims with a 19.5mm interior width seems pretty damned good, especially from a “big” manufacturer. I wonder if the new Bontrager hubs hold up better than my old RaceX Lite rear hub, one of whose flanges decided to break off?

The guy that designed those hubs is a friend of mine. He says they’re not as light as DT Swiss 240, but they are going to be more durable. They have better seals and stronger freewheel engagement mechanisms.

With aerolite spokes to boot! Makes ordering direct from China less appealingfor sure.

Can it really be a Bontrager frame if it doesn’t have gussets?

All – Sorry, we meant to put that photo on the top and accidentally loaded the wrong image. It’s fixed now.

Now that I’ve seen it, it was worth the wait. Trek need to come out with a Trek Bontrager based on that design, it’s one the cleanest steel roaders I’ve ever seen.

Looks like you can run a 36c in the rear & a 28c up front ???

Probably the stock fork from an Emonda SLR disc….which only clears 28-30c tires.

The article leads with the steel bike and there are no photos. This is not good work.

The road helmet is the Circuit, not the “portal”

I like steel frames, TIG’d, lugged, brazed, they all appeal to me. But I never understood all the hype about his frames. I remember seeing a few of his MTB frames back in the day, it was a frame, it worked. Other than that, meh. This one kind of falls into the same category, it’s nice.

I’m with you. I fail to see what so incredible about this frame compared to many other available steel framesets.
It honestly feels a little “beige” and just a tool to hang parts on. There is no tube shaping when many steel builders are using shaped tubing on the TT, ST and DT based on lessons learned from CF and AL frames. Just look at the BB. Zero of the larger real estate was used by the DT/ST.

Shaped tubing doesn’t necessarily mean a better performing tube. Round is the best overall shape for handling the complex loads that a bicycle goes through. The shapes you see from carbon and aluminium are mostly to facilitate the joining methods for those materials and aero in some bikes. Adding shape actually takes away some properties and can add weight to make up for it. Don’t automatically assume a plain steel round tube bike is going to be a bad bike. They usually are among the best performers it;s just they don’t look fast standing still.

I think in a day and age when some of the bike design and tubing choices are so exaggerated and form over substance, it is really nice for some of us to see clean lines, functionality and simpleness. I really love this bike.

FYI: When the article reads: “A few other things worth looking at include their Portal road helmet and Rally mountain bike helmets use their Blendr mounts that attach magnetically. Quick, easy integration that’ll break away if you wreck….” you’ve got a mistake.

It should read: “…include their CIRCUIT road helmet,” instead.

Don’t know of any portal helmets by Bontrager.

This is the coolest bike I’ve seen since a red Cherubim with Campy a few years ago…Simple, sleek, strong, sexy, the perfect balance of old school steel and modern tech. Me like.
