[Closed] Pike A1 to C1 Debonaire ?

You need the full air shaft kit, not just the red bits. Al specified too because the air shafts weren't the same length as the B1s onwards.

As Scienceofficer says, as long as you get the full £40-ish air shaft and seal head kit, you're good (you can get the seal head and foot nut alone for £25-ish, but you need the air shaft as well). I've just done the sane upgrade with a 2018 Revelation and it was dead easy.

I'm looking on the TFT* at https://www.tftuned.com/2021-c1-debonair-air-spring-upgrade-kits-pike-yari-lyrik/p3851

This say's B1+ ...

Whereas

https://www.tftuned.com/2019-20-b1-debonair-air-spring-upgrade-kits-pike-yari-lyrik/p3412 has Pike A1/A2 and I'd need a .007 for 160 on 27.5 vs .000 for a B1+ or Revelation?

*(Because they also have stock on the pawl set I need)

edits ... I meant 160mm

as long as you get the full £40-ish air shaft and seal head kit

This, I had my fork upgraded to the new airshaft last year and when collecting it left with the old airshaft, this year there was no airshaft to take home as its only the seal head kit which has changed.

The second link is just the 19-20 Deb air spring, not the newest C1, it says in the bottom of the description "PLEASE NOTE, THIS IS NOT THE 2021 LATEST VERSION OF THE DEBONAIR AIR SPRING".

Go for the first one - the kit is the C1 air shaft, foot nut and seal head.

I recently bought this for my (2015, 160mm 27.5) Pike. It looks the same as the TF tuned link above but I must confess I glaze over when people talk about A1/B1+ revisions so I don't know if it's the latest model. It was £28 when I bought it a few weeks ago.

Anyway, it was transformative. I'm not usually one to buy into suspension hype but that made a big difference. Highly recommended from me.

No. Neither of those kits will be right.

The implication from TFtuned stock is they dont have what you need. If you phone them and speak to an actual person, you're likely to find they can give you advice on what else will achieve what you need.

J-Tech appear to have C1 air shafts for A1 forks mind.

Yeah I guess phoning... seems best. Not sure if its stock or website screwup though (as some of the A1's must be the same length ??).
J-Tech have them but DPD shipping is £6 ... and TFT have the spring I need for my hub and my kids shock so might be able to get them to ship it back in the same courier.

Hmmm. So TFT say's it's not compatible ... not a stock or website issue?

So you cant make an A1 Pike into a C1 Pike in one go?

Not according to TFT... they said Rockshox updated compatibility as it doesn't work well.
I'm tempted to try anyway as its for a 35kg rider... and test back to back with a 2019 airspring.

He's running my forks at the moment on a very short headtube and the steerer really needs chopping down if he keeps them (which will make it nearly unsellable)... or I'll just put the airshaft in his forks (which I just serviced)

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?

@steel4real

It's weird... I have the RS SPC downloaded anyway so that was my first point of call.
How are they riding? Sounds like a top out perhaps?

I've not noticed anything adverse - they seem OK to me and I think I prefer to the 'B1' or first debonair upgrade but I only really wanted them to hold the fork up a bit more along with installing the 2.1 charger damper. It's been in for 3 months so reasonably well used and I did a lower service yesterday so I'm not planning to change back for a while. May reconsider if I notice a concern or at the next service which would be a full one anyway.

Bike tart are cheapest and post free, got one last week.

apologies for bumping up an old thread but I've just fallen into the same mistake trying to upgrade my 2017 A2 pikes to C1 DebonAir. They are no longer officially compatible
Am I right in thinking that a Vorsprung Luftkappe A1 would be my best bet now??

I've managed to pick up a Charge 2 Damper (not 2.1) for a bargain so am looking at other upgrades while the fork is opened up.
Thanks!

Can you put the fork crown serial number into the Trailhead App and see if it gives you the options ?

<span style="font-size: 0.8rem;">I upgraded my A2 Pike a while ago, to the last but one airshaft and that's how I found out the options.</span>

Yeah I've done that and it's saying the previous version of the debonair spring works. For some reason the 2021 C1 Debonair spring won't fit a A2 Pike now.

I'm sure I read somewhere a B1 air spring will fit but I could be mixing things up. I can't find where I read that now, thought it was the TF website

If I understand correctly, it does physically fit but the C1 assembly isn't quite the same size (it's a little taller between footplate and seal) so it doesn't equalise the chambers correctly when fitted into an older fork.

It's a bit more expensive but I have a Luftkappe in an A1 Pike and it's very good, no worries about compatability or how much of a difference it'll deliver which I gather is pretty variable with Debonair swaps depending on your exact model. I was really unhappy with the stock fork but the Luftkappe made it decent, all it needs is proper Dual Air and it'd be really good I think. But I can't compare with the Debonaire.

I'll have to check my part numbers but I essentially fitted the most recent air shaft to an old Pike and it definitely wasn't right, was too long came out 170mm and didn't feel right, not consistent.

I wouldn't worry too much about the difference between the B1 and C1 upgrades. I already had the B1 in my yari which was a vast improvement, changed to a C1 out of curiosity when I last serviced and the difference is fairly small. I sort of go along with the comments you'll find on mtbr etc. that the C1 is a wee bit harsher on small bumps but has more support, however it's all within a few psi and a couple of clicks of compression imo.
The step change was upgrading to the B1 in the first place.

Cool, and just goes to show 'expired' topics are still current 😉 6mo later and I'm still dithering but a lowers service is now in order (and may as well do the damper whilst I'm at it) so a good time to reduce travel on the HT.

I think it has a Luftkappa in at the moment. TBH got lost between full rebuilds so its either on my HT or the kids FS. (Essentially I have 2 1/2 A1's with parts swapped and scrounged to make 2 working ones)

cheers

Now got a 2020 Debonair spring coming which is listed as the current upgrade. May buy a Luftkappa at a late date and fit to the original air shaft and try that. But I think I'll be happy with the current upgrades

I did this, 2017 pike to a upgraded 2020 debonair when it was listed as an option..I think I saw on here that the guidance had change so I called TF Tuned and indeed, the 2020 debonair is no longer officially compatible with the 2017 pike. Something to do with the dimple height for the air passover being in the wrong place so would make the fork knocky and notchy.

Being risk averse, I took it out and swapped back to a longer travel pre-version of the red spring.
