Push coming out with a V2 of their Nine One inverted fork. Damper and chassis are the same, but new spring system that let's you toggle a ramp up on/off. Seems pretty cool.

Why are you ruining the chainstay length discussion with this actual tech news?

At the time they still had the 37mm crowns from the 26 inch days so there’s really no excuse

Aren't those being used on 27.5 forks now?

You’re right, even less of an excuse for not having 37mm offset 29ers 

I have a new-ish 29 fork with 37mm offset and you can have one, too. You just have to built it from the parts yourself.

I like my Hugene 2. 

I'm not sure if I would buy the new Hugene 3. It seems like it takes a step towards being more of a XC bike but doesn't go all the way.

My 37mm offset aspirations are in direct conflict with my Fox podium aspirations Sad

You’re right though, a 37mm offset 38 or zeb would be pretty easy to build

I feel your pain. I was forced to switch to 44mm offset when I got an Intend fork. The 37mm fork now lives on my HT.

If I may ask, what would be the goal? Slacken the head angle more with hopefully less wheel flop?

I think a shorter offset lets you corner more aggressively. You reduce the shopping cart effect so when you lean over on your side knobs the front wheel is less likely to tuck. At least that’s what I noticed going from 51 to 44 back in the day

Only supposed to be a rear rim, but uses the letters than many companies exclusively use to denote front tires/wheels/hubs/rim. Curious 

(I'm aware it follows DT's preexisting naming convention)

Will the DT police arrest me if I run these front and back?

Jokes aside, It's nice to see an alloy rim manufacturer make something recognizing the issues that heavy guys run into with alloy rims. I have yet to get an alloy rim to last me more than 2-3 months of consistent use before they develop stress factures at the eyelets or they simply won't take a sufficient true anymore. I'd consider trying out one of these seeing as it's purpose built, however!

 

Edit: I can't find any release info on this rim, and I certainly haven't been paying much attention, but this blog post from 2022 mentions the rim. Odd.

Wasnt the FR541 ment to be the 'last' Rim you buy?
did it not live up to expectations? 

I've been running ARC30 rims/vault hub along with Turbine wheelsets and They've been fantastic an good pricing/warranty(havnt needed)

I've been absolutely wailing on FR541s on my heavy ass ebike for a year now, including a few hits hard enough to flat DH tires, and the rims are still mint. I'm sure there are people out there destroying them, but it takes a lot to do it.

I have dented 2 fr 541 and split 1 at the seam this year alone.  I do race DH, but run fairly high pressures.  I think there is definitely a place in the market for a beefed version.  

Also seems weird that all news coverage of this new rim is from aus and New Zealand, so maybe it’s been around down there for awhile?

The FR 541 has been the worst rim I’ve ever had. Bent 2 of them to where they wouldn’t hold air within months. Nothing out of the ordinary: 170lb rider, park bike, DH casing tires at 30 psi, experienced rider but do not race. I’m going back to Flow EX3s on the park bike and am trying the Reserve alloy on the enduro bike.

This is partially unrelated and unimportant but does anyone know what the numbers mean for the DT Swiss rim naming?

Tristan just added the details to that Wheelworks post this week

The NZ distributor had the 571's listed on their "New Products" list before even DT had them listed, and they seem to put quite a bit into marketing DT products here

I've been smashing some new wheels coming out of Australia: https://ride-wingman.com/

The alloy rim is super tough and has held up better than the DT, Reserve Alloy and Stans I ran previously, plus it comes in silver

Marleens (NZ DT agent) even without Nic onboard now, have always been pretty onto it with marketing and product support.


I have to say I'm surprised noideamtber hasn't killed that ARC30, worst rim I've every had... even weaker than the 1st gen Stans Barron rim.

Second this. Dented one so bad it wouldn't hold air, but somehow the tire survived? Got a new wheel built with the same rim, did the same thing the very next day, again the tire survived. Every other wheel I've owned would flat the tire long before denting, even with a DH casing.

The annoying thing about mountain biking is that there's such a huge difference in abilities, and those differences mean that high performance bikes are heavier while prebuilt/cheaper bikes are lighter because it's "higher performance" even though it isn't. It affects rims more than anything else I reckon. Products that we'd destroy in one run can last for years under 90% of riders because 90% of people trundle down blue trails. And it means things like Treks, or anything with ARC30s, etc are totally unfit for purpose out of the box.

Very different from something like motocross, where out of the box, the bikes don't perform well but they last a lot longer than one lap. Or skiing, where it's way more common to build a setup with boots/bindings/skis that actually suits you rather than buying a locked-in collection of parts.

Are you sure you're not talking about the cheese AR30? Those are awful rims.
the ARC30 Is quite good, Im not a light weight and it got thrashed over summer at QT skyline and CAP.(+ other places) - i was not kind to it, its killed many tyres

This has been my exact experience. Conti DH tire survived both times. They were in wildly different conditions too. One was the flat rocky bottom part of the Snowshoe WC track (aka not very high speed) and the other dent happened on a flow trail in the mud (again not going fast whatsoever). Wasn’t on a drop or feature, just  basic rocks in the trail.


Just rented the Polygon Colossus DH in Morzine and it had these rims. Flatted the tubes in the rear twice but the rims were ok. (one literally right before mainline 10%) I tend to go a bit easier on rentals though. 


I want to like DT because my XM481s take an absolute beating on my trail bike and have dents all over them still holding air no problem. Great all mountain rims.
