Another thing about dual crowns on enduro bikes is that modern 29” DH forks typically have pretty whack fork offset numbers, often 50mm+. For instance, the old 40's from 2019 were 58mm!! Would be cool if Formula offers this fork with a 44mm industry standard enduro offset. They could even offer it in 44 and 51mm offsets to match what's available for single crown forks.

Fox, Ohlins, and I think RockShox offer crowns separately so you can swap to a shorter offset.

Agreed would be nice to have the option to buy the fork with them.

Fox and Rockshox only go as low as 48mm for 29" forks, Ohlins goes down to 46. That's not so much longer than 44, but it's still longer and as you said riders still have to buy the shorter offset crowns aftermarket. In the case of the Formula dual crown, it's designed to be run at lower travel amounts to match enduro bikes, so a "normal" enduro offset seems like a no brainer for Formula, especially considering it's probably not designed to be run at 200mm travel anyway.

  Aren't the larger offsets necessary to accomodate a useful turning radius and the large diameter stanchions?

At least for Fox, you can go to 44mm. There's no distinction between 29 & 27.5 crowns.

There was a rumor a while ago about new enve wheels 

anyone know anything?

New mountain wheel lineup is coming this spring.

Assegai, DHF, DHR all come in soft light casting options IIRC.

Bit of a speculation on the most possibly never going to happen nukeproof reactor V3. All the comparisons are made with the current V2 generation in mind. (I consider the old hardtail as the V1 generation)

Would be nice to get a full rundown from Mr. Page himself. Or would be possible to buy the prototype from him?

- Geometry
Geometrywise it might have got a standard longer slacker lower treatment.

- No Cable Tourism
All the cables are routed internally, yet not through the headset. Hooray! 

- Horst Link stays
I was expecting a flex pivot. If the rear travel stayed 130 mm they could have implemented flex pivot. Specialized and Merida can solve this on their frames that has more rear travel.

- Brake line disappearing into the chainstay
Instead of routing the brake line outboard, they are now going on the inside of the chainstay. It would have been nice to have a fully external brake line solution.

- Brake + rear derailleur line over the bottom bracket.
At least the brake line is over the bottom bracket, but the rear derailleur line is not visible. Possibly because of AXS? Definitely an improvement over the current model where the cables / lines are routed under.

- Bottom bracket housing looks to be quite big in dimateter compared to the bottom bracket. Could it be a T47?
With all the 30 mm spindles, and outboard bearings the wall thickness of the standard BSA bottom bracket is quite thin. T47 could help on this as it allows for thicker walls. Can not be a coincidence that Hambini makes BSA/30 mm bottom brakcets in titanium.

- 2 Cable ports on the downtube for brake line? 
As the frame is made of carbon on the picture, and it must have inside channels for the brake lines, I suppose that one channel is coming out next to the headtube on the left (for EU) the other is coming out on the right side for UK / moto people.

Have you tried a Rocky (ignore the typo in the instructions....) Whistling Rocky Moto

The 29 and 27.5 crowns on the newest 38mm Boxxer are interchangeable.

I've got a 29er 38mm Boxxer setup with 44mm offset crowns and reduced down to 190mm travel on my enduro bike. Pretty sweet setup, but a bit heavier than a single crown fork (can't say I noticed that).

Also, only 8mm longer axle to crown than the 170mm 38 it replaced!

Considering how much of the world runs brakes moto style it blows my mind how many manufacturers don't make allowances for it.

I wouldn't consider doing it with a carbon frame, but I did drill a Commencal alloy frame for moto routing a few years ago, as they are one of many brands that just thinks everyone runs their brakes the way they do.

Evil has guided internal routing for moto or normal brake routing

As far as I know it should be 43mm just like the short offset regular Selva 👍

Specialized T9 available in Grid Trail casing which is EXO+ or maybe a little more stout level.

O even lighter "grid" casing, and that is closer to exo+ I would say. Stout enough for bike that has to be pedalled up hill unless you run very low pressures for some reason

I haven't ridden a 29er dual crown (how many of us have?), or a dual crown at all in years. The EXT fork feels noticeably stiffer fore-aft than other single crowns I've ridden, IDK if its their CSU interface or just lower friction in the stanchions & air spring prevents flex to some degree. The 38s/Zeebs I've ridden have all been in need of a service, so I didn't get the best impression of them. I'm wondering what tangible benefits, if any, a lightweight dual crown has over a well built, modern single crown? I don't feel like I want my EXT to be stiffer. The only advantage i can think of is more travel for a given axle to crown length.

selvas already have ~10mm less axle to crown than other long travel forks

It's definitely a big thing to consider. Seems to become a problem at around 46mm. 

My current way to solve this problem is to run a reach adjust in the long position and run the 46mm OS. Plenty of steering radius like that. Assuming you're not at your reach limit already.

Levo Alloy Öhlins Coil LTD |

 

A "new" levo.  same same just different components.  Alloy aswell.  are they selling out the remaining alloy frames with a new paint job and some ohlins gear?  a stop gap until the new model ( which then feels like thats going to take longer again )

nice colour though and finally they have some stock locally so might be tempted, but its top end price for an alloy model

Semenuk riding a Trek 'Sesh' in his latest edit. I'd assumed a mulleted slash but the shock mount looks like a much beefier version of the ticket.

Screenshot %2811%29 1.jpg?VersionId=qLfEC2z

It seems like it's more or less a long-stroked (accommodated by a new shock mount) Gen 5 Slash frame with a lowered top tube and some reinforcement at the TT/ST junction. If I had to guess this custom frame is somewhere around 175-180mm travel with 27.5" front/rear (Semenuk rides a full-DH Session at other points in the edit, and seems to have swapped out the Vivid for a SDU on the "Sesh") and would probably make for one hell of a fun park ripper. Love it but I can't help feeling sad for the next-gen Remedy that never was (unless this is secretly it, but that's doubtful).

Just got back from a day at Dyfi. This is the production-ready model, two were being tested by journalists in preparation for the official launch on the 12th. 

In person it’s absolutely striking and looks like nothing else out there. If the frame only price is reasonable then I’ve never been more tempted by a bike. 

(If anyone from Atherton bikes wants me to remove the photo I’m happy to, but as it’s been seen by upwards of 100 people today I’m sure it’s fine). 

 

Has anyone heard any rumors how the new Atherton aluminum series ride?  I waS all gung-ho to order, but saw in the email they sent out this week that it uses a dw4 and not dw6 suspension platform. So imagine it’s going to ride fairly differently than their other bikes. I imagine they are gonna go quick when they are released, but also don’t really wanna order without at least reading a couple reviews

If you want a shorter offset on your dual crown fork, you can always just flip the crowns backwards and re-install the stanchions (assuming your crowns have offset). I run a 56mm offset boxxer on my Spire with backwards crowns. This reduces the offset to 36mm. The turning radius is just enough to not notice. I also had to make sure my tire wouldn't hit the frame before bottom out since the reduced offset brings it closer to the down tube.20240314 201412 0

That's kinda crazy looking... What travel are you running that boxxer at?
