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?

The full 200mm. Static geometry is a bit wild. The HTA is below 62⁰. However, im running ≈45-50mm of sag (25%) so the dynamic geometry still feels normal. I'm using all 6 volume reducers for bottom out support. Its kind of a weird set up, but it feels really nice.

Troy riding a diapered high pivot sender on instagram

Here you go

Can folk please learn how to post from Instagram. It’s not hard and took me a few seconds to grab that still from his story.

Tip: use the “post video” function for an instagram post.

A generic “there’s a pic of someone riding a new bike someone on the internets” is a bit pointless.

Not sure if this is the right place to share but here's a couple thoughts/rumors on random bike stuff after attending the Sedona bike fest

1. All the guys that brought their DJ and bmx bikes lost to a guy that was on a demo yeti sb135 for the bunny hop contest. It's the rider, not the bike.

2. Always wondered what gearbox bikes felt when you tried to shift underload - it doesn't shift! I was climbing a not very steep road to get back to the venue on a (demo)Zerode and was stuck in gear 4 all the way up. The grip shift just would not budge until I completely stopped pedaling. I think there's still some improvement to be had there. The guys at the booth said the back wheel should track better due to being lighter, I personally could not tell. I did miss the ability to shift under power though.

3. The TRP DHR evo brakes felt wildly different from the Hayes Dominion A4s. I have the Hayes, and they have a super defined bite point. The TRP levers are also light action, but the braking feel is much more linear than the Hayes. Also, the Hayes felt like they had much more stopping power. Just my thoughts, as I see these being compared to each other a lot all around. 

4. Heard that EXT is releasing a DC fork within this year. 

5. There were SO many people demoing Yetis. Not sure because of the appeal or maybe just because they have the largest demo fleet. Norco only had 1 size of each bike. 

6. Tried pulling the maven levers (on someone's bike, with consent), they are pretty stiff. Friend who has Codes are actually pretty excited for them, me not so much. My hunch is that if you liked Codes and you need more power, you'll like Mavens. If you didn't like Codes to start with, Mavens probably won't change that. 

7.Saw some kids with older hardtails having great fun on Hiline. Anytime on a bike is better than being on a couch.

This works on some non-dual crown forks too.  Pull the lowers- rotate 180, re-assemble.

How much of an issue is the bridge clearance then? But the same is true for dual crown forks too anyway...

Regarding gearboxes, with the Pionion it's known you have to let up on the pedals to release the shift mechanism. On their end of line check in the factory apparently they shift under full power, but drive the shifting mechanism with a big motor. So the design/parts take it, you're just not strong enough with the gripshift to shift it. 

I think the electronic shifting mechanism improves in this. 

With effigear talking with the designers they used direct drive hubs in order to drive the gearbox forwards with the wheel during shifts in one of the directions to release the pawls. Using a freehub rear hub would otherwise require backpedaling to release the shifting mechanism and enable the shift to be made.

Is anyone else bothered by them installing the silver Mavens on this bike?  It may be one of the only bikes out there that the Van Halen calipers look good on!  It literally has matching Trek decals on it.  

Looks like he did get some red ones for the shredit, phew.  Whistling

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. 

I remember Chris Porter writing somewhere on Instagram that part of reason for the larger offsets on dual crown forks is that they deflect less than single crown forks. I took that to mean single crown forks have a larger effective offset than the static 42/44mm when you're actually standing on the bike because of how they flex.

I have the logical and obvious answers for all of this so Ill get to it. 
 

1. steroids.

2. Weak wrist probably. Thought you were shifting it was just your wrist clicking.

3. Oh no… not lever feel again…

4. Is it more or less than the Push?

5. Largest demo fleet. Size matters. 

6. Just going to ignore the lever feel stuff

7. Fuck yeah!

(Also just being a satirical douche. I like to bring some humor when I can. Im sure your wrists are plenty strong Wink)

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 

Yes they're DW4 aka VPP aka DW Link etc etc. 

It's to save costs, less links, less bearing, so also cheaper servicing which is great. 

They should ride similar to all other short dual link bikes, so peppy and playful (compared to horst link).

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.

To each thier own but that turning radius looks unusable for anything other than going straight down the hill.

So all dual link bikes ride the same way, that's good to know.

Seeing as how DW6 is both dual link AND horst link, how does that ride? Wink

I would bet significant amount of money that you overestimate how much steering lock you apply at any speed above 10Km/h

I can see a dual crown fork limiting your steering if you ride really slow speed tech.

I'll take your money, I know the lock I use like the back of my hand. But in reality, counterpoint, would you want to ride a setup that has a 10kmh minimum? 

Also, the crowns look like this to me:

More steering lock means more stoppie nose pivot turns!

Switchbacks are a bit of a pain and whips feel a bit awkward sometimes. I kind of enjoy the challenge on switchbacks though. I have to maximize every corner like a Formula 1 driver to prevent myself from riding off the trail. 

Also, that picture of the helmet on backwards is perfect

CNC alloy lug bonded to alloy tubes makes so much sense for small frame builder. Can build around easily available tubes, bond joint be slightly away from high stress area and custom geometry should still be possible if desired depending on design.

Really excited to see where this could go in the next 3-5 years.

Plus it minimizes or completely avoids the need for heat treatment of frames. You can heat treat individual tubes/ lugs before bonding. That should simplify assembly and minimize issues like alignment. 

It also open up the door to using other allows that are not weldable like 7075 IIRC. 

 

Plus it looks sexy AF.

Yep, but I guess a marble is still required, even if alignment will be a lot easier.
