On the note of disengaging hubs and pedal kick, so long as whatever drive mechanism you have can automatically engage when you pedal forwards, it's impossible to prevent it from causing pedal kick. The drive mechanism, whether it be hub or BB based, can't differentiate between the chain getting pulled on due to you pedaling and the chain getting pulled on from the suspension compressing. Riding backwards is a little different in that you can use the fact that the hub is rotating backwards relative to the axle to disengage the hub.

What if you make hub engagement so slow that your suspension can fully compress without the hub catching?

It is called oem formula hubs

Looks like BOS Suspension is back on track with its MTB range:

https://www.vojomag.com/news/bos-suspension-revient-avec-une-nouvelle-gamme-vtt/

-> Idylle DH fork / Idylle SC (now named Kyll) (39mm stachions anyone?) / Deville + a DJ fork (the USD Obsys should be back too -oh word I'm hoping for a SC version)

Weren't they back into MTB twice already? All I rem mber is the CEO spitting his dummy out over how nobody in MTB appreciates them and that they're never coming back. And they've come back twice since.

However, those parts look straight out of 2004, absolutely no thanks. If they're not gonna make themselves a viable option by actually selling their things, then it's all a moot point anyway.

I don't think they actually left, idylle SC and DC were introduced relatively recently just after RS and fox came out with 38mm range, stoy3 is also one of the newer shocks on the market. Anyways, like to see them still going, my stoy rare is damn good shock and as reliable as they come.

can this hub be reliable?

As with every other free hub mechanism out there, if tolerances are right and material choice/quality suitable for the application, I think it's not very complicated at all, however their track record + general inclination towards weight saving in the worst places that is so prevalent in the whole industry... I'm little skeptical.

Personally as someone who is tired of seeing pastel painted bikes, Kashima or Black stanchions, I welcome something that makes me think of the era of mountain bikes when bikes had sick paint jobs from the factory, 27.5 was new, 1X was becoming a thing. Enduro was new as well. I dig em. Probably still better than X Fusion.

What are you all hearing about the new SC e bike(s?). Named Vala, 160/150,Bosch system 5, non VPP, 600wh with an extender are the rumors I've compiled. Maybe an updated Bullit to follow?

A few forums already have informations on the bike since last week.

Bike will be 4 bar linkage, influencers are flying over to Santa Cruz for the media day that is happening either today or tomorrow.

Bosch Gen 5 should be releasing in the next few days with 600wh & 800wh battery options, new eMTBs should be flooding right after including the new Vala.

Frames designed with the new Bosch 600wh will not be able to fit their new 800wh, so they really want to slot the new Vala between the Heckler SL and Bullit/Heckler.

Also looks like new Devinci Troy is releasing this Wednesday.

e*thirteen's new Sidekick Hub is here, and I had the opportunity to spend a day riding it back-to-back with a regular hub to see how it works and how it improves suspension performance.

I started a new forum topic to chat about the Sidekick HERE

Once again BOS is intentionally choosing a pointless stanchion size for the sole purpose of fucking up the few customers who were willing to give them a shot and try something new when BOS inevitably folds the MTB side of the business.. There's several options on the market from seemingly stable, boutique suspension manufacturers, whether it's just dampers or full forks/shocks. I don't know why you'd pick the one that launches a product on a Monday and ceases to support it by Thursday, but instead of choosing something like a 35, 36 or 38mm stanchion on the forks which would allow their users to change to a different wiper seal/o-ring after BOS calls it quits, they pick something stupid like 37 or 39mm.

I spent a bit of time on their stuff in 2016 and thought it was really good. The bad part came when customers wanted their stuff serviced and we had to tell them that their quite expensive suspension product was, in fact, a large paperweight after the first season.

Curious about the benefits (or lack) of the sidekick on a shorter travel bike.  120-140mm travel range.  Would it depend more on the suspension kinematics of the specific frame?

interesting, but you have tested a 29" rear wheel with an aluminium rim against a 27,5" carbon wheel, correct? if so, how can you be sure you perceived the influence of the hub and not the wheel size and rim material?

You're correct on wheel size/material differences. I do think the new carbon rims had a positive effect during high-frequency chatter and muting that type of feedback. I'd say the front rim provided more benefits in those situations than the rear.

I was focusing on a few corners with deep, repetitive compressions, one rock garden section, and high-speed braking straightaway with some bumps to hone into how each hub rode differently. The change from the DT240 to the Sidekick was most noticeable in these moments, as the suspension was freer off the top and was less jarring on big hits. It just felt like the bike was getting out of the way of impacts easier and working through its travel more smoothly. The 29 vs. 27.5 I figured would put the e*13 at a disadvantage through the rocky bits as I've ridden that test track a ton, and it always gobbles small rear wheels (and fronts). However, my bike was skimming and driving better through those holes and felt more active with the e*13 wheels than the stock 29/29 DTs.

The differences or improvements with the hub during my one day of testing were marginal. But there were plenty of benefits that I felt like I only scratched the surface of, which makes me eager to get a hub on my enduro bike. @TEAMROBOT has a long-term hub/wheelset heading his way this week so that he can weigh in on descending & pedaling performance + durability + Ochain comparison. I'm really curious how the lag when pedaling changes with a 12-speed drivetrain or when going up tricky tech climbs. With a 7-speed DH cassette pedaling to the lift or cranking for a jump, it wasn't an issue.

Sorry to say, but from what I have found out from either personal experience of from other suspension service centers in central Europe, bos is not using any proprietary seals and certainly weren't using them back in 2016 either. It's only "certified" suspension centers that for some reason refuse to visit the nearest o ring store that had the problem. The were all regular metric seals/wipers available immediately and for pennies and if you so desire in multiple compounds so you can try to improve already good frictional properties. And till recent forks with 39/42 mm stachioned forks even fork seals weren't unusual sizes and supplied by multiple aftermarket makers. What they could and should have provided is spare parts list with dimensions/compatibility. So from my point of view, that paper weight ended up that way because of lack of effort on service center side more than anything. Should they be selling spares directly? Sure. Is it big issue when they don't if you can get all the seals needed for your shock basically anywhere in the world for 5bucks? Not in my book, at least when it comes to regular service.

For those of us who don't have the privilege of being in Europe, finding 37mm seals was absurdly hard prior to the Mezzer coming out. SKF, for example, didn't offer anything. We found a couple sets on international ebay but those either didn't work out or the supply ran out quickly. You're saying I could have walked down to the neares "o-ring store" and walked out with a 37mm seal kit? Really?

I could see being outside of Europe making things harder. Still, their forks were 34,35,36mm back in the day, you had to pick the only one with unusual diameter and didn't think forward and buy few spare seals up front. Anyways, good seal store will make you one off seals if you really need it, won't be cheap. Or take care of the forks and seals will easily last 2-3 years.

There should be a law that once a product is EOL and is not supported anymore, the specs for the spare parts should be freely published. Including, for example, the dimensions of frame parts to be able to either weld up cracked parts to correct dimensions or have someone be able to recreate things.

Right to repair really can't come quickly enough.

If your argument is that when you buy your new fork for hundreds of dollars, make sure you buy enough spare parts for it also for 2-3 years. Your really not understanding consumer behaviour and justifying shitty company practices that shaft consumers at every chance.

@CascadeComponents can you please explain for the dummies if the E13 hub works as advertised or not, now you know the full product and how it works. 

It works as advertised for the most part. There are still scenarios where pedal kickback can be encountered, but they should be pretty rare. Let's consider the current generation Nomad for an example. The suspension has to compress about 80mm to get 18 degrees of pedal kickback. Because you are always guaranteed the same amount of slack in the hub, on any compression smaller than this it does make pedal kickback impossible to encounter. If you are compressing your suspension more than 80mm, it then becomes a question of how fast is the shock moving when you hit the 80mm mark and how fast is your wheel spinning. If your wheel isn't spinning and you get past 80mm of compression you will encounter kickback. When your wheel is actually moving, the criteria to get pedal kick is that the chain has to yank the freehub enough to take up all slack in the hub and be moving fast enough that the freehub spins faster than the hub shell at the point where slack has been taken up. For most impacts the shock should be able to slow things enough that you can't achieve the combo of having all slack taken up and freehub moving faster than the hub.

Compared to a low POE hub, this is different in that you are guaranteed the same amount of slack every time. Let's say you have a hub with 18 degree increments on the pawls. It could take 18 degrees for the hub to catch or it could take 0 depending on where the freehub is sitting relative to the shell. On average it'll take 9 degrees. So you'd need a 36 degree hub to on average have the same experience as this hub. The on average bit is important though. Also 36 degrees would be a lot...

Oops Asa Cycles! A few things to be gleaned from the details:

Bontrager Brevard - new Assegai/DHF clone?

RIB(2.0)'ed for her pleasure. 

Curious they call it the Rail+. The + typically signifies the ebike version of a preexisting model. Is this new rail twice as much ebike as the previous one?

Also, Damn it Trek, you're speccing deore on the lowest model, why the heck aren't you speccing deore linkglide??? It's THE E-MTB drivetrain!
