It wouldn't work as the steerer tube flares so the race is a tight fit. If you put a spacer on first, the crown race isn't going to stay in place and will move back and fourth on the steerer.

Erm, is the inside face of the crown race tapered to fit onto the bottom of the steerer tube? How is the race going to sit square, & how is the race not going to crush & lock up your bearings when you tighten the stem cap if you add the 10mm spacer?

Just a thought.

you can get extra thick crown races for this purpose, on-one used to sell them IIRC

sorry - not made myself clear - not to ride just to sit on and get a feel.

It might work. The question is whether or not you can get the spacer to fit over the bulge at the bottom of the steerer.

why not just put the front wheel on a plank of wood or similar?

As Onza says, it'll be difficult to impossible to fit a spacer over the bulge at the steerer bottom.
Why not measure the depth of the bulge - say 5mm - then add a 5mm spacer (for example) to make up the required overall distance?

Just don't bloody ride it like that unless you want to bugger up your headset and/or steerer tube!

what he said, find out the axle to crown size on the forks your thinking about, subtract the sag and lift the front tyre up on a book or some wood that amount to see how it sits

as other when you factor in your sag you are talking about 6-8 mm difference. If you can notice the change then I have a test with a lot of beds and a pea 😉
Ps i think it will work to test as will plank but it is next to no difference IMHO

You got an air fork on it?

Just put a few more PSI in that.

You do ask some daft questions on here.

I am afraid I'm with the rest - I don't think you'll notice it just sitting on it. I noticed 120mm and 100mm on the handling whilst out riding but I don't think I'd notice the diff. just sitting on it sorry 🙂

I am trying to ascertain whether 10mm more travel plus 10mm headset cup will feel better. The 140mm Fox talas feel too short - too much weight on my hands (read the post regarding carpal tunnel). WTF it is to do with some of you i will never know!!

Why not but a whopper of a front tyre on and let the rear down a bit, at least youd be able to ride it.

I've got a 10 mm crown on one of mine and it makes no difference to your hand problem, trust me I know.

How about asking your wife as she might have seen someone looking a bit shadey outside a shop in the peak that had a 10mm spacer in their dodgey looking car. 😉

How is something solid going to give you an idea of how extra travel will feel? Depending on the fork, 10mm extra travel may not even mean the head tube is any higher anyway

iirc they are longer a-c than most other brands

feel free to laugh and point if im wrong

or even if im not 😛

Rob - just ignore them. Your question has as much validity as most turrets questions or those about head angle, crank length or frame material.

🙄

If you've got too much weight on your hands, try setting your bike up properly, getting your weight properly spread over the bike.

Fannying about with 10mm is pissing in the wind.

Your post said "run" a spacer, so most folks probably assumed you wanted to ride it like that. From a practical viewpoint, the steerer would be thinner 10mm up from the crown race dia, & hence a bit weaker. You could get some sort of part turned, that would sit on the crown race & slim down to the req' dia 10mm along. Not something I'd do, after seeing a colleagues forks snap on some steps after he tried something along these lines many years ago.
10mm would probably make a bit of difference on some razor sharp race ht, but not a 5-6" FS bike. (IMO obviously).

To get the weight off your hands, increase the height of the bars. If there are any, swap the spacers from above the stem to below it. Or higher rise bars.

High rise (40mm bars already)

Shorter stem fitted, 150mm forks (were 140mm before) and a thicker bottom cup - happy rob for now 🙂
