Good point about the stiction, yeah. I mentioned that USD forks should be stiffer in longitudinal direction since the tubes are larger (and/or thicker) in the place where the bending moment is higher - towards the crown.

Boxxer is listed at 5.76 lbs and Bartlett is 5.7 lbs so it’s 27 grams lighter, which almost an ounce. The Bartlett has a boost 15mm axle whereas the Boxxer is boost 20mm, so if you go with the Boxxer, you also need a different wheel.

It is only future-proofing (having 20x110 Boost front axle) IMO...

Shimano Saint 2020? Or are they going to leave it for another year? Not seen any proto parts about, the spd pedals were around for a while before a full version made it to market.

This is honestly my most anticipated tech news right now. Saint is loooooooong in the tooth.

Shimano and FOX stuff based on what Greg showed up to this point. And the Devinci Spartan is what, 1 year old at this point?

I would have expected a change to 15 mm would occur with Boost hubs instead of the 20 mm boost standard coming out. But it's hard to see how that would get sold. You can't sell stiffness, it's hard to sell weight to DH guys (the way I see it at least), in the rear going 135, 142 or 148 gives you supposed width advantage over the 150/157 hubs (narrower frame, 'harder to snag rocks'), etc.

Interestingly, 15 mm hubs should be more durable though. With bicycles using disc brakes you are limited with how big of an OD bearing you can put in the non-drive side of the hub. With a 15 mm axle, you get some more space for the bearing on the ID. That means larger balls and, in practice (considering the load carrying ability specification of said bearings), more strength. And that means more durability.

Ah, the details Smile

TBH, if I'd do research on linkage forks, I'd be head on into research of fully integrated versions like Structure Cycleworks. If you're going at it, might as well go all in.

It was just the current spartan but with all the new devinci sponsors. Paint job looks sweet tho, wonder if that’ll be available to the public.

Wide range TRP drivetrain coming soon? Looks like it says trp on the rear and the styling/general shape seems similar to their DH derailleur.

Well, the 20 mm hubs use the BB tool instead of the cassette tool, so not 'THAT' different as opposed to the cassette tool.

15 mm was developed with Fox, yeah, but dunno, to say it was only developed because of center lock? That seems a bit of a stretch to me... It might have been an influencing factor, but i doubt it was the only one.

It looks like Bubba Warren is riding a new Evil Following.

Why didn't they use the 20 mm axle that everybody was happy with, then? Remember 20 mm Reba's? Wink

Yes, I forgot that you open it with a BB tool, because I avoid Centerlock as much as possible. And don't forget Shimano has quite some history in wanting to shove us their ”innovation” down the throat: Biopace, initial Octalink, those damn Dual Control levers etc

Also remember they pitched that a 15mm axle was lighter without a significant loss of strength...

Is it me, or does the front triangle look different compared to the current V10?

I love centerlock for travel. So much quicker to remove and install for packing a bike.

We might just be looking at different sized frames.

New 38 also has lowers air bleed ports and axle pinch bolts. Apparently it’s very heavy
