I am doing an enduro event in the new year and need a new bike as my current bike is a 2015 Transition Scout. I do however have some decent parts to swap over to a suitable Enduro frame from a hardtail including a near new 160mm Lyrik Ultimate.
I have spotted a 2021 Privateer for sale at a great price; trouble is the frame is intended for a 170mm fork with a zero stack headset.
I was thinking that rather than buying another fork (which would be more than the frame) would be to put an external cup headset on to take up some of that lost 10mm and maintain the geometry. The actual travel would then be 160F, 161R.
Is this a terrible idea?
might be possible to fit a 170 sprint to your Lyrik, depends how old it is, they went to 180 at one point
What George said, and I know the stock bikes came with a 170mm Lyrik - because my pal had one.
Fork is a Lyrik Ultimate FS-LYRK-ULT-D1 from the serial number. When I check it out on Rock Shox trailhead it shows 140/150/160mm airshafts so I am guessing it cannot go to 170mm. Whilst I was getting the serial number I measured the external cup at 11mm... if external 56mm headset cups are available then it looks like it would more than make up the difference. But it might be a terrible idea!
Yeah, they shortened the available travel for the Lyrik range a while after the Zeb arrived - probably out of luck with a D1 Lyrik.
The external cup will do the job, I don't think it's a terrible idea.
Can you fit an external bottom headset cup or one of those Niner/Reverse/Chris King 10mm extender bottom cups to tweak the geo back to a 170mm fork? They’re usually cheaper than a new fork or air spring
As above, get a crown race extender/spacer thingy to retain the standard geometry with your 160mm fork. Newer Lyrik's can't go beyond 160 since the Zeb was introduced for longer travel scenarios
Now I am sold on the idea (and the frame has been reduced further!) I am having trouble finding one of these headset extenders.. the Wolftooth one seems to be no longer produced and a lot of the stock left is not for ZS56, Reverse don't have them on their website and the Niner one is +15mm and availability in UK/NZ might be an issue.
Does anyone know of somewhere likely to stock one? My internet search skills may be lacking!
If you tend to run a few volume spacers in your Lyrik, take some out and add some air. 20% sag on a 160mm fork is the same A2C length as 25% on a 170mm fork.

One of these may do the job, 5mm and 10mm in stock at Ison

Though personally I'd try running the 160mm fork without first, it may be fine?
MRP Riser Crown Race looks great - same problem solved the other way round! Thank you!
It may be fine without but the issue is that I don't own the bike yet so trying to ensure this sort of part is available before I buy the frame!
I see no-one else has done it, so here goes (sorry!) do you need a new bike for this enduro event? If you ride a bit and you're comfortable on the Scout, you might be quicker on that than a new bike. Plenty of people ride enduro events on hardtails and short travel bikes.
If you're relatively new to racing, is it something you're going definitely going to do more of, or might you end up with a bike that's a bit much for most of the riding you do?
Don't want to put you off getting a new bike if you want one, and the Privateer will suit the riding you do anyway, but you don't need an enduro bike to ride enduro events.
But I've just read the NZ part - maybe what you've entered does require an enduro bike!
