Really, can couple of kilos tops of handlebars and levers plus a bit of frame can compress a fork.
My 74kg must really squash the fork to its limits
I have a couple of forks with Lyriks fitted. Its very noticeable on my E-bike due to the weight of the bike but don't really notice it on my enduro bike.
should have realised the look of the fork when stationary is more important than the loss of performance when riding it.
Why would you say that? Did you read my previous comment about my BB being too low?
I'm going to get a 10mm longer shaft anyway and this new one will help make a more meaningful difference to ride height.
Happy now chuckles?
I've just upgraded to the Debonair spring a few weeks back.
I went for a 170mm shaft to replace the 160mm solo air.
Will see how this and the Charger 2.1 RC2 damper upgrade I did at the same time goes when I can get some decent mileage and set up time on them.
The new foot nut and seal head might be worth a go as it's only £25 and can be put back to normal if I don't like how it rides.
Did you read my previous comment about my BB being too low?
That isn’t going to help with the ride height when you’re on the bike. The fact the negative air spring is smaller means you’ll need less air for the same ride height which in turn will mean less support and bottom out resistance.
From reading the comments over on PB sounds like the Vorsprung guys might be coming up with an alternative solution to the travel loss issue.

People who have actually ridden the new spring are using the same pressure.
Yes, I'll take the word of the manufacturer and those who have actually ridden it, thanks Poah.

I've a 2019 boost revelation 140mm travel. Will this fit? On the drop down menu on j tech site they don't list a revelation? I also found this when I shopped around for a charger damper for my fork. Any idea?
I fitted the damper in January and it's probably covered 300miles on new skf wiper seals, would they be OK to reuse of I dropped the lowers again for best to replace?
Better call j tech on Tues, he is very helpful IME.
I usually re use all seals at first lowers service.
The 2018 onwards revelation uses the same chassis as the pike, i.e. 35mm so it'll fit.
The compatibility chart shows 2018 and 2019 pike/revelation 35mm both use the B1+ spring.
For anyone who wants to upgrade, Birds are selling them here:

Thanks @benpinnick for making them available.
Ordered the upgrade bits for my 2019 Yari/Lyrik from J-Tech. Decided to use lockdown for a full suspension overhaul anyway, so may as well do this at the same time.
Ordered the upgrade seal head from Bird for both my bikes. Cheers for the link. Ended up changing the travel and doing a lower service start of lock down on one already, at least I'm well versed!
Think I'm going to order this part and increase the travel to 160. I've got the lyrik select.. do you think it's worth upgrading the damper to the 2.1 RC damper? I've heard it's do much better
Alas I just found out our date has been pushed by 2 weeks (they were due with me today). I asked whether its just mine or everyones incase you can cancel with us and re-order elsewhere. I will email anyone that pre-ordered once I know that answer.
Mid June according to J-Tech:

Would be nice when companies release products that you can go out and buy them straight away...
J-tech are saying mid June for the seal head kit?
this is despite Rockshox claiming they are available in the UK already in several replies to several different posts on the subject on their instagram...
If you go to the Bird site, the seal head is no longer available for pre-order.
Im guessimg the current circs make this stuff uncertain in delivery.
Quite exited to get the new stuff for my older Pikes

Yes Jtech just sent out an email saying potentially mid June for the parts. I've read a few reviews and have seen 6 no negatives yet so I've pre ordered. Let's see how long it will be.
Zyrofisher (UK SRAM and Rockshox distributer are showing 8-12 weeks until seal head kits are restocked.
However the full C1 debonair air spring assemblies are in stock and shipping immediately, mine has been despatched today!
#lockdowntinkering
R2-Bike say 1-3 days, I just ordered a 170.
160 shows in 1-3 days also (Edit - I had the old version there a moment ago)
If you go to the Bird site, the seal head is no longer available for pre-order.
Im guessimg the current circs make this stuff uncertain in delivery.
Yep and they'll stay offline now until I have them in my hands! I don't like changing dates as it lets everyone down and for a relatively small part its not worth the hassle of keeping everyone updated! I have plenty on order so when they are in my grubby mitts they'll go back online. At the moment the date is early may, this could change of course. International shipping is slow at the moment as there's a lack of air capacity and ports are clogged with uncollected stuff.
Everyone that had a pre-order on many thanks, hopefully you got the email.

Yes, got the email thanks. Hopefully they’ll be here soon.

pretty much what I said on page 2 🤷♂️
I was told 8-12 weeks, I ended up buying the new updated airshaft and will return the unused shaft I bought last week
J-tech Suspension have just shipped my 2021 Airshaft 🙂
is the pike ultimate still size B1?
J Tech have suggested week of 27/04 for my airshafts
My JTech 2021 upgrade parts to fit to the air shaft turned up today. I've done a lower leg service, fitted new SKF seals and foam rings and swapped the Debonair parts.
Forks definitely sit higher. Once we are out of lockdown I'll find out out how it all rides...
Our JTech bits arrived this morning, will get them fitted in the coming days

Did you order the whole air spring assembly, or just the seal head and nut?
@poah: You called it correctly.
Have been chatting with a mate who has been on RS for years and he said that the 2021 air spring makes the fork harsher, so it sounds like you were right about the negative air spring being smaller.
Basically, you're better off with the 2020 fork and air spring for price and performance.
Many members had much riding with the 2021 air shaft? As above I've seen a few people say it makes the fork harsher, does exactly sound like an upgrade and now half temped to cancel my order, its not been dispatched yet
I just updated with the head and nut. No riding yet to know what it feels like other than a bounce in the street...
I ordered the whole spring assembly. Easy enough to fit too. God knows when I’ll get to ride it though!
Managed to get hold of an upgrade kit 🙂 just need to get around to fitting it now.
Where did you get one? Unfortunately orders from j tech have been delayed a week
good PSA thanks.
just ordered from 18 bikes and they have shipped already!!
I cleverly had mine delivered to work. I suppose it can wait until normality returns.
Anyone got any ride reports/feedback they'd care to share on the 2021 airspring?
Yes - I fitted this latest 2021 air spring to a 2016 Pike B1 (160mm) that already has the previous Debonair spring upgrade in it and a Charger 2.1 damper as well. Used the same pressure and can confirm the fork sits that bit higher at rest and so I effectively have 20-25% sag whereas before it was nearer 30% to get the ride feel I wanted.
The change from the original solo air to the fist Debonair was very noticeable with a definite increase in small bump plushness.
This latest '2021' or C1 upgrade felt good, subtly different but riding the same trails (Peaks - Winhill/Ladybower 'offpiste') this weekend just gone on the 2021 air shaft compared to the previous weekend on the other air shaft definitely felt better. Same trails, same conditions, very dry, dusty, rooty and sometimes rocky. Strava also logged a few PR's and I've ridden those trails a fair bit over the last two years or so. I didn't notice much, if any, change in small bump but I think there was something useful going on in the mid stroke that maybe held the front up a bit and improved confidence on some of the steep bits. Of course some of that is probably down to a freshly serviced fork (the small bump always feels a bit better in the fist few rides!). Overall it felt good and I liked it, so better, but hard to pin down exactly what. Certainly nothing adverse stood out.
Good to hear - my upgrade parts from Jtech are arriving today 😁
I've got about 10 hours of dry weather lumpy riding on the new debonair c1 in my 140mm Pike.
So far I think the armchair theorists are correct - it is a bit more reluctant to move off the bat on the small stuff.
I didn't like it at all at my B1 debonair pressures, so I dropped the pressures by 5 to 10% and installed an air token.
Set up like this there's the tiniest suggestion of a bit more reluctance to move off the top (it's pretty negligible) but they are much better than the B1 air spring when you're pushing on.
Weirdly doing a static sag setup they appear too soft, but when you're actually riding the bike they're perfectly fine.
Overall for my style of riding the pros outweigh the cons.

My reading of that is it's less about changing the volume and more about changing the pressure in them at sag?
So at top out you still have similar pressure (and therefore sensitivity)
At bottom out it's irreverent.
At sag or mid-travel there's less pressure in the negative spring because you've started with a smaller volume but stretched it by the same amount. Effectively making it begin ramping up sooner?
Who knows!?
As a pretty average rider and I was having such a good time riding I didn't care to think about it.
For £42 I was happy to try it out and bring forward the routine lower service a little along with fitting the upgrade. No clear reports of it being anything other than good and it was - for me. But that's the thing isn't it, not everyone is going to have the same experience, riding ability, conditions, weight, expectations etc. etc. so a n other may not like it. I also like the fact that RockShox make their latest improvements reverse compatible - I'm effectively riding a Pike Ultimate 2021 :-).
I'm a couple of rides into my updated fork(202Pike Ultimate) and my thoughts are very much inline with @scienceofficer.
Trundling up a fireroad, maybe not so keen to move off small stuff...but it feels more poppy, composed at speed and holds a line better i think.
I really couldn't get the previous spring set up to my liking...i think this is going to be much better for me and most riders I would say.
Ok so im after a 29er Lyrik Ulitmate for my new build sounds like the best way to go then is a 2020 Lyrik Ultimate from R2 bike then upgrade as and when the 2021 DebonAir shaft assembly is availbale? That sound a sensible route to take? R2 bike ok to use see a few people on here have, just wanted to check.
Anyone know any more info on the new Rockshox Zeb fork yet?
I'm finally taking the plunge on a '21 ebike as I can get one early & it comes with the above. The models relate to the Lyrik (as in it's still called the Ultimate RC2) so i'm just assuming its a bigger, beefed up version?
Zeb has 37mm stanchions and by all accounts is a good fork, but if you need a stiffer fork and don't do bar spins or X ups, the Boxxer is a better option. Not that you've got the option, but it's good, basically.
So it seems that something has recently changed from Rockshox with regard to the compatibility of the C1 Debonair upgrade to A1 & A2 Pikes (2014-2017)
From the current spare parts catalogue (SPC) 2020 revh - this is the compatibility chart;-
But the 'Debonair upgrade and travel change kit manual revD' advises that they aren't compatible and instead advises the previous debonair shaft;-
I bought my 160mm C1 shaft from TFTuned so I've asked them. Apparently something might start tapping not sure what. Seeing that I bought it from them when it was compatible but now it isn't it seems a bit of a concern?
