[Closed] Steerer tube too short?

[#10577723]

Hi

I’m in a situation where my steerer tube sits 9mm below the top of my stem, so the top of the steerer tube sits at the mid point of the top stem bolt, is this too short or will it be okay?

Forks are Fox 36s and a husselfelt stem

Thanks

Yes, too short imo.
Look for a low stack height stem. Lots about with stack heights of 32mm or so and you will drop 10mm off the height of your current set up.

Have a look at a Funn Funnduro stem, should sort you out without too much outlay

Yup, as above, low stack height stem should sort you out.
Easy to find options are DMR Defy (31mm), DMR Swarm (32mm), and Funn Funnduro (32mm).

There are cheapy copies of the Funn stem on eBay (Wake I think?) But it depends whether you trust your teeth to a £5 stem!

I had this recently so you have my sympathy. I already had quite a low stack headset. Went with a DMR Defy stem, not only is it a low stack height, but the bolts are both in the middle rather than at the top and bottom. Problem solved, just!

And the DMR stem is pretty awesome looking too!

so the top of the steerer tube sits at the mid point of the top stem bolt

I think it will be fine. The bolt should tighten up fine without distorting the stem. A lower stack stem will still only be contacting the same amount of steerer.

A new steerer is 60 euro from ND Tuned, need to strip the fork and a press to install. (or get it installed during a full service)

Any chance you can fit a lower headset top cover?
Lower stem?

Low stack height stem, or a single bolt stem (3T for example), but I'd also add a short section of steerer tube if you have one, so that the stem doesn't deform when you clamp it tight. I had something similar and I was clamping a threaded 1" stem with an insert. This was in a TT bike, so not as bad stresses.

Thanks for all the replies, opted for a low stack stem in the end. I’ll see how it goes with this fitted.

If not I’ll have to look at a replacement steerer tube I think

Hussefelt stem is way beefy and big stack no?

Yeah the husselfelt is a 40mm stack height, the one I’ve orfered is a 30 or 32mm so I should be alright

Any idea on the cost of a new csu?

Could you remove a spacer and make it up with a riser stem ?

Thanks Bruneep, I’ll get in touch with them, their Instagram looks good. I wasn’t aware that you could change just the steerer tube alone.

To the spacer comment, there are no spacers fitted on the head set unfortunately

I ran a rigid single speed like this for a years worth of pounding around Cannock. I popped an off cut of steerer in to stop it crushing the stem.

My steerer is, if i admit it, a tad short!
Not as short as yours, mind! The stem is 1mm below the steerer... but i had to get high rise bars to get the hand position in the right place!
I think if you can easily look at a new steerer, go for that option..

The low stack stem should come today so I’ll see how that is when fitted. Has intone had just a steerer tube replaced on fox forks? Most companies advise against it it seems but places like the above offer it

Another vote for RSF Suspension. Give him a call if you do get in touch as he's stacked with work and doesn't get much time to answer messages or emails!

Fox, Rockshox etc do not offer replacement parts, only complete CSU. They do not authorize repair/modification of the CSU.

ND Tuned sell fork steerers and some stanchions. RSF can supply most stanchions/steerers.

The steerer is a press fit with a lip, its not going to fall out once assembled. The stanchions are a press fit, and then the top cap threads into them securing them to the crown. (obviously assuming no components are damaged and they are pressed out/in straight)

I fit them with a loctite retaining compound, can also be used to fix a creaky CSU.

You need to make or buy some tooling (ND Tuned and Blue Liquid Labs both sell tooling) and need a press and the tools to strip the fork.

Avoid :-/ Had heart-in-the-throat moment whilst pulling out bolt with completely stripped out thread during handlebars change.

Your "pegs" are not worth that 20-30-odd quid savings over real stuff.

Cheers!

Thanks all for your help. The Funn stem has worked for me fortunately. Just enough tube to get a nice camp onto it so should be all good to go!

Yup totally agree. Especially considering the Funn stem us only £25 on CRC.
