I built up a Slayer a few weeks ago, I guess the concept is similar to the new Rallon, only that it doesnt have the option for 200mm in the rear.
Didnt have the opportunity to test out all the geo settings, but so far I am really happy with it. It climbs very well and is insanely fun.
I hope I can test it with a full DH rig tho, would be interesting how it compares.
I'm sure there are companies that would be delighted to make a 250mm shock compatible link for the slayer
I guess my 170mm Balance fits this category, although it was built (not bought).
What do you think is better: an endurofied dh-bike (with a wide range cassette, a dropper and suspension that can take a beating), or a downhillafied (😅) enduro (with a dc-fork and suspension that isn’t as plush and forgiving as a full on dh)?
Yes.
Depends on what you want to do with it, no?
Both are compromises IMO. With the DH-ified Enduro, you get the dual crown confidence and maybe some change in the head angle. With the Enduro-ified DH bike you get the possibility of seatpost insertion issues, and unintended effective top tube lengths, and it may have bad anti-squat characteristics, so unless you get a new shock with a lockout, or it comes with one, you're potentially hamstringing yourself.
It's best to pull for a bike that's designed with such uses in mind. I can think of 3: the Ghost Poacha, which comes with a 250x70 shock, and you can overstroke it for DH travel. The Lapierre Spicy, it comes stock with a 205 shock, but uses a yoke on the lower shock mount that you can take off to run a 225 shock for DH travel. And the Orbea Rallon, which can be changed between the two travel options by changing out the lower shock mount (and I think mounting a shorter length shock, but don't quote me.)
These three bikes have been designed to pedal properly, even with DH travel, so they are the best candidates for that. Vitus were also going to come out with a bike like this, and the designers even ran it with DH travel and 12 speed gears while testing, but the company went under before the bike could be released.
If you were mechanically inclined, there are a few bikes with interchangeable lower shock mounts that are good candidates for a DH travel conversion, like the new gen Trek Slash, but I don't think anyone makes a kit for those yet.
Ihm, no, not really - in both cases I wanna climb up a 20+km fire road and then bomb down a sick 9km superenduro trail, for example. Just wondering which compromise is better…
Why not getting a bike designed for such a use case then?

Cause I’ve already have a bike - I’m on the “endurofied dh-sled” wagon with a dropper and a Windisch range cassette. Just wondering if my choice is the right one, or if it’s a better idea to ditch the frame and change it with a superenduro one. Devinci Chainsaw comes to mind!
oh my god beautiful bike.Its a shame these short chainstays and me have parted ways..I had previous generation of the balance and now after a few bikes I cannot go back to short chainstays,
anyways.. about this topic, to me the one of the best frames is the Canfield one.2.... 200mm, dropper compatible.. you can short stroke to 180mm, pedals fantastic. Its badass looking.
Here in 190mm front and rear in dh mode.. thinking about dropping some pedal friendly bits again in a few days (dropper, cassette), have done it before.. just dont have pics
Always have had a DH bike in the past, but haven't the last couple years. Rather than buy a full bike I just bought a Fox 40, and put a 180mm airshaft in it. Was a pretty simple choice in my eyes, got the fork cheap, and was easy to swap end caps on the hubs. So I just travel with one bike and 2 fork's...a Fox 30 170 for the pedally days, and the 40 for more shuttley , chairlift park days.
part of me regrets making this thread and being jealous of all these bikes now.
did you consider leaving it at 200mm given DC forks can end up around same a2c as a 180mm single crown? or did you run the math and figure the 180 downshaft ultimately ended up closer to the 170mm a2c of the stock bike?
i feel like with some of those specialized bikes... a bump in BB height would be preferable to extra drop. not sure about the enduro specifically though.
I fully intended to lower it to 180mm. I picked it up from S4 Suspension in Quebec/ Whistler, they didn't even charge me for the machining. I still have the 200mm shaft for resale value/ maybe one day I'll try it. I very roughly measured A2C of my 38, and the 40 is slightly higher. But not to much. BB height is a touch higher as well. I think I am still in the low setting with the chip. I could have totally dove into matching numbers more closely, but I was pretty excited to get riding haha.
Beautiful bike. Is there any concern about the dual crown on the enduro? How does it handle w/ the dual crown vs the single crown?
I've got an enduro collecting dust at the moment but I feel like a dual crown could really spice things up. I recall when they first came out a few were circling around but the hype seemed to die down and people were reporting issues with the carbon at the headset.
Thanks! I was a bit concerned about the head tube issues, but mine is still fine. I think if the HT was going to have an issue it would have happened by now. I've found a few online reviews and such from the first year of this model actually being approved for a DC fork. PB mentioned it in a review, NSMB did as well. I think I've even read it on Specialized on the 2020 model.
There's a definite turning radius change between the 38 and 40, but we all know that. I just find the 40 to inspire more confidence in the rough stuff.
Felt this was a fitting place to post my thoughts on running a Boxxer on a Spire. Spoiler Alert: Its the best setup I've run thus far.
I genuinely don't understand why we don't see this more often, from ~160-170mm on up. Especially on e-bikes. I suppose price is part of it, but my real guess is what I'm going to call "mimesis"; we all broadly follow more than we lead. And breaking convention is hard.
Watched it last night, good follow up video and i do agree with you. I ran a 180mm boxxer on my megatower 1 for a short period of time and it was awesome. At that time, I measured the 180mm boxxer to have pretty much the same axle to crown as the 170mm zeb and the difference in flex/bushing bind was noticeable under extreme duress. I did notice the steering limiting effect of the dual crown on 3-4 trails I ride regularly that had excessive switchbacks (san juan trail in socal for those that know). That being said, with some adjustments I was able to clear all of the switchbacks on that trail and there were only a few switchbacks in my local riding circuit that I couldn't figure out or make happen... and let's be honest, that's skill and not a true hardware limitation.
I do absolutely see no reason why we aren't running DC's on ebikes. I have a current (new) generation santacruz bullit and that bike would be prime to put a dual crown on. I think your comment about USD's potentially having many of the negatives of a DC and few of the positives is spot on.
I'm on board. I've been running a dual crown on my Canfield for a couple of years now, I have the newer boxxer now. Two of my friends have them on their E-bikes. I also had the MRP Bartlett when they came out. I thought it was a great idea and would really take off but it never caught on. I wonder if Fox or RockShox came out with something like that how it would go over. Great videos.
I pushed the rock shox product manager to keep the 35mm Boxxer and update with a tapered steerer and 15mm axle for these bikes.
Shot down.
Would’ve loved that.
Formula has the Belva DC enduro fork, anyone ever see one in the wild?
Watched it last night. Definitely see it as a more compelling idea for big ol ebikes compared to the Podium or even a run of the mill 38.
The notable downside being so many ebikes have tubing that wouldn't be pleasant to run with a DH fork. Turning radius of a winnebago...
I absolutely love my previous gen boxxer on my pedal bike. I have a 15mm axle conversion and with a direct mount the stem the weight difference to a 38/Zeb is absolutely negligible. Being able to run a longer spring for the same axle to crown is just an added bonus.
The super wide top tube of my spire did cause some steering issues while climbing with the short offset crowns but the narrower tubes of my frameworks enduro has been trouble free.
What' the need for a tapered steerer on a dual crown fork? You just have to get a reducer crown race to fit your headset. Straight steerer allow more room for anglesets or reach adjust headsets.
@jeff.brines how could you not run a DM stem?
Because @Dave_Camp didn't have one (its his fork
)
Tapered steerer to show that it’s a direct 1:1 replacement for a zeb or 38 whatever. I think a lot of people don’t understand the reducer crown race.
Agree you don’t need it, and it’s probably worse.
Trek Slash isn’t DC rated per the PM, he said it met the other CAT 5 standards.
What would be the benefit of running the older 35mm boxxer on a pedal-able big rig? Just the lower cost?
It was quite a bit lighter
Post a reply to: Anybody buying these enDHuro sub-200 dual crown builds? Are they valid or cheap fan service?
