[Closed] Could i run a 10mm spacer under the crown race on my forks?

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!

no fear of riding it like that!!

Rob - is this for the mmmbop? Would you like to borrow a High Stack bottom cup to try ?

10mm ?

FFS, just let a bit air out of your back tyre to feel the MASSIVE difference right away

druidh - didn't know they did one? that would be ace - how deep is it?

I think they're 10mm bigger than the low stack unit, got one on my cannondale HT.

WTF are you going to find out by sitting on it with a 10mm higher front end?

look out up there, if your raising it 10mm I hope you dont suffer from vertigo

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 🙂

just mr ralph trolling again with silly questions,still whip his butt on a downhill 😉

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!!

WTF it is to do with some of you i will never know!!

So why ask on a public forum then...

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.

Stu i asked could i do it not what your ****tish opinion is, ok?

get you big boy.

kiss kiss. 😆

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

shorter stem to move you back a little? or a higher rise stem?

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. 😉

*waits for childish email from big boy rob*

if i was married a possibility, as i am not .....

if i was married a possibility

Oh so i'm still in with a chance then.

*polishes up chatup lines in a northern accent.*

thought of a 10mm spacer rob or is that not.complicated.enough?

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

al thats my original question

Watch out with the answers he doesn't want to hear or you'll be accused of ****ism. 😆

Hi-rise bar?

a better idea would be to try a pair of marzocchi's

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).

How do i go about doing that? Shorter stem?

[i]How do i go about doing that? Shorter stem? [/i]

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.

spacers - check and can do (also getting a longer fork!!)
High rise (40mm bars already)

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

Why not a stem spacer Rob?

wanted it to lift the frame up not the stem - already got 20mm spacers under the stem and it would LOOK shit

Had you decided to get the forks before resting it on a piece of wood / putting the spacer at the bottom of the steerer?

Thing is Rob, as it's one of your bikes, it already looked shit!

Rob- if you're still having trouble with your hands after the fork swap try playing with bar position. When I first got the Evil I'd fitted RaceFace Diabolus bars and the first few rides I had pain in the ulnar nerve area. Rolled the bars forward (quite a lot) and no pain in 3 years.

Shorter stem seems to have help as i am sat more upright rather than being stretched out.

Yes because they can be adjusted travel wise so nothing lost

and you work that out by? Al your a 40+ year old solicitor, hardly qualified to give advice on looks. Stick to the brown suits and shiny shoes dude!!

lets have a photo of the bike. i already have an idea what is wrong.

Ergon grips do help. I know someone who's got knackered wrists from climbing / manual labour and they help him alot.

10mm makes a difference.

I added one 5mm spacer under the stem on my race bike - big difference, made it a lot easier in the singletrack.

Don't get ergons rob. They're practically dangerous.

and spazzy

Try making sure your saddle is level, if nose id dipped too far forwards it naturally puts more weight on your wrists/arms etc.
Not sure from photo as it's a bit skewhiff.

Go on, I'm intrigued. Why are Ergons "practically dangerous" then? I've been riding with these since they first came out, they make a significant difference to hand and wrist comfort, and I've never noticed that I was courting disaster by using them.

rotate your brake levers up a bit. this has made a huge difference to my riding.

I have ergons, currently on my hybrid. After 3 hours on them the other day my hands were in serious discomfort 🙁

I quite agree Ergons may not be for everyone, still don't see why they'd be "practically dangerous" though.

RobJ you are a teacher. I win!

no you don't you have abnormal arms! Oh and i get 13 weeks holidays a year ergo i win!

Another couple of spacers under the stem won't make it look that different.

Its not about the bike....

You are RobJ.

I win.

will as you know full well it is, if i can't ride it properly it MUST look good when i am pushing it! 🙂
