First Sven, Now Boone – Introducing Trek’s All New IsoSpeed Equipped Carbon Cyclocross Bike

Boone_Katie2

You’ve met Crockett, now meet Boone – Trek’s all new carbon cyclocross bike. Confirming months of speculation, Trek’s new bike introduces the IsoSpeed decoupler to the world of cross racing, a move that makes a lot of sense. IsoSpeed is all about smoothing out the bumps, but also about being able to put the power down which should both help when motoring over frozen ruts. Like the Crockett, the Boone was designed in partnership with Katie Compton who helped dial in the geometry. Nearing the bike’s competition it was placed in the hands of Trek’s latest racer Sven Nys, who according to Trek said, “it’s perfect.”

Explore the new Trek Boone after the break.

In addition to the IsoSpeed decoupler, Boone expands their OCLV carbon line of cyclocross bikes. Previously, carbon was only available in the the Cronus CX line which started out as part of the Gary Fisher Collection. The carbon Boones now sit alongside the Cronus CX Ultimate and Cronus CX Pro. While 600 series OCLV carbon keeps the bike light, built in carbon armor keeps it tough.

Since this is a cross bike after all, the Boone features a weather sealed frame to keep mud, sand, and pressure washers out of your IsoSpeed decoupler and cable routing. Designed with routing for mechanical or electronic shifting, the frame is equipped with a new internal battery mount if you choose to go the electronic route. Also, if you choose to stick with cantis over discs, the frame offers cable stops directly over both brakes. The disc brake frames use post mount fittings that can run a 140mm rotor.

For those not familiar with IsoSpeed, it is essentially a bearing system that decouples the seat tube from the top tube/seatstay junction. If you were to remove all of the hardware, the seat tube is not actually connected to the frame at this spot with carbon. Instead, there is an axle that pierces the seat tube and allows the tube to flex absorbing the vibrations and “doubling vertical compliance.” Compared to the Domane, the IsoSpeed decoupler has been pushed back slightly to offer easy shouldering of the frame.

Like most of Trek’s carbon bikes, Boone uses a BB90 bottom bracket and carries over the 3S chain keeper from the Domane. Along with full carbon rear dropouts on all models, the disc brake models include vanishing rear fender mounts so you can keep training, even in the wet.

Like the Crockett, the disc and cantilever frames are platform specific. Meaning no changing your mind on brakes – it’s one or the other. Of course, Boone offers Trek’s seat mast design which builds in compliance, and adjustability in a travel friendly, no-cut design. IsoSpeed isn’t just for the back end of the bike, as the fork has received the bump absorbing treatment as well. Using a rearward curving dropout, Trek claims the fork is better able to absorb road vibrations further smoothing the ride.

Nice to see Trek and it’s industry clout supporting cyclocross. Good reporting, guys and gals.

mudrock - 01/01/14 - 9:49am

I see that the fork looks unchanged between the canti and the disc models, even tho the stresses on forks are quite different between the two. I’m sure they took that into account, but I wonder if there’s much fork shudder during hard disc breaking.

Stampers - 01/01/14 - 10:13am

where does the “Boone” name come from? place? person? event?

JasonK - 01/01/14 - 10:17am

Stampers: it looks like Trek is going with ultra-American names for their bikes designed for the ultra-Euro sport of cyclocross. Crockett refers to Davey Crockett while Boone refers to Daniel Boone. Both were American frontiersmen.

Dave - 01/01/14 - 11:10am

Wow. Best looking bike Trek makes. The white/green one is da bling shizzle.

Sevo - 01/01/14 - 11:29am

Mudrock-shutter comes from canti’s that have the housing stop not a the fork. Mini v’s cure this and it’s a non issue with discs

Erik_A - 01/01/14 - 12:34pm

Crocket: Compton/Rocket or Davie Crockett
Boone: plays on the latter with Daniel Boone.

Nick - 01/01/14 - 2:40pm

@mudrock
The canti brake bikes have a full carbon fork, including steerer tube; the disc versions revert to an aluminum steerer. And my guess is that the wall thicknesses or carbon layup is different on the disc vs canti forks, despite them looking the same

@Dave I’m digging the green one too, don’t know why trek decided to only offer that color with rim brakes. Since it’s the SRAM option, I’m wondering if there was going to be a disc version with S-700 brakes

wako29 - 01/01/14 - 2:55pm

@Nick: it sure looks like that’s the case. If you take a look at the Crockett lineup, the Boone has very similar build kits. The Crockett 7 Disc uses the S-700 brakes. And seeing as how those brakes can’t be sold right now (or however you want to look at it), I wouldn’t be surprised if Trek just decided to pull the bike from the launch at the last minute.
Back on subject: Holy crap does this bike look awesome!

graves - 01/01/14 - 2:58pm

As a descendent of Daniel Boone, I demand a royalty check, but will settle for a free bike.

Carlo - 01/01/14 - 4:47pm

good to see how peaple look surprise to se an updated gary fisher 2009, and can maybe think Sven nijs is really excited about it!

Jeb - 01/01/14 - 9:18pm

Liking the fact that Shimano is finally using group specific cranksets (Ultegra) with proper cross sized rings instead of those CX-70 cranks with the sh*tty stamped rings.

Bababooey - 01/01/14 - 11:14pm

Finally trek, finally. Isospeed is a great addition. Aside from that, it’s hard to reinvent a CX bike. Besides, if it’s good enough for Sven nys, then it’s good enough for the rest of us

Henry - 01/02/14 - 12:10am

The photo of the black, disc only Boone 9 frame shows what looks like an eyelet near where a seat stay bridge would be. They can be seen in the pic where KFC is shouldering her new bike as well. Is this a mounting point for a “brake bridge” and fenders? Also has a pair of eyelets on the back of the seat tube. Am currently riding a Domane and the Cronus CX with the disappearing fender mounts (a feature I love) but don’t recognize what these new/extra eyelets are for?

cory - 01/02/14 - 6:45am

Boone & Crockett is a hunting conservation group, named after the two frontiersmen. It is maybe the first thing that jumps to my mind for a company from WI.

But somehow I was hoping the bike would have been named Tubbs.

fakemind - 01/02/14 - 7:49am

It should be called the david boon.

BMS - 01/02/14 - 8:57am

@Henery it nutserts on the seat stays are for a bolt on bridge for fenders. If you are not running fenders it does not need to be one. The nutserts behind the seat tube are for the internal Di2 battery.

Steve @ G4G - 01/02/14 - 12:00pm

It seems odd the front cable stop on the fork is removable, but the rear on the frame is not. Kind of a bummer for those who prefer mini-v brakes. I love my TRP CX8.4 brakes.

Local Dutchman - 01/02/14 - 12:16pm

8 National titles ok, but 4 world titles on Nys’ bike? Did I miss 2?

Dave - 01/02/14 - 3:04pm

and they are sold out of the disc 9….

G-Man - 01/02/14 - 3:50pm

@Local Dutchman – ’97 & ’98 U23.

Bas Simons - 01/02/14 - 3:52pm

I think they counted his espoir titles, too

But now I think of it, that frameset would make a pretty cool roadbike with disc brakes. With smaller tyres it’s not that far off a domane. Perfect for a fast downhill of the stelvio.. :P now just wait until Shimano comes with some less ugly levers..

CDG - 01/02/14 - 4:12pm

From Trek on Twitter regarding the names:

“Bit of backstory over our CX bike nomenclature: Davey Crockett & Daniel Boone were early-American pioneers. CX bikes are for exploring!”

John - 01/02/14 - 7:01pm

@BasSimons: Maybe a precursor to a disc brake-based Domane? Trek could be waiting for Shimano to announce actual Ultegra hydraulic disc brifters…

I don’t know about you guys, but I’d buy that bike in a heartbeat.

tkeaton - 01/02/14 - 8:48pm

oh wow….”brifters”

and to think i was missing the days of bikeforums.net

/sidenote

John - 01/05/14 - 1:57am

Any reason the internal cable routing ports were moved from the headtube location used on the Domane and Madone to the downtube on the Boone?

@tkeaton: You’ll let me know if it’s not kosher to say “internal cable routing ports”?

Nick - 01/05/14 - 11:49pm

John- “internal cable routing ports” is not only fine, but an accurate description. But “brifters-” I die a little inside whenever I see it (or *gasp* those thankfully rare times it’s heard aloud.) If it were an acceptable term, than Shimano, Sram, Campy, or even Microshift would use it, or it would be in the QBP, SBS, Hawley, etc catalogs, but its not BECAUSE IT IS WRONG

As for your question, I’m guessing it has to do with the weather proofing Trek is advertising with the new frame. Although it may also be to simplify routing of hydraulic hose on disc bikes, which although functional with tight bends, would be more difficult to route through the head tube.

Another thought is that it may be because it’s relatively easy to twist the cables around each other on the domane, which has the cable ports directly above each other on non-drive side. The mad one has cables entering further apart, and in my opinion is easier to deal with than domane cables, although the rear brake cable has a frustrating tendency to hook the derailleur cables when recabling.

Tom - 01/07/14 - 12:32am

Am I the only waiting anxiously for a Superfly hard tail that incorporates the iso-majig?

larsv - 01/08/14 - 1:30pm

@ Tom: Good point!

kurti_sc - 01/08/14 - 1:47pm

@John and Nick,
I’m lost on the ‘brifters’ thing. is it for brake lever / shift lever combos?

Do y’all remember those grips that used to make motorcycle sounds when we were kids? That would be an awesome feature to add to Di2. you already have the battery. vroom vroom…

aaron - 01/10/14 - 12:53pm

i don’t know about anyone else, but i think of crockett and tubbs – 80′s Miami Vice, then offer retro 80′s colors.

This frame would be way better without the arc to the top tube. Make it strait, traditional styling.

The ibis carbon cx frame has the best style.
