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
