Is there a lower stack stem than 31mm?

[Scotty675]

I just bought a dmr defy stem thinking it would squeeze in. FAIL. Trying to make a Mac ride fit my pivot. Drama being I’m running the 17mm bottom cup to slacken it a little. Is there a shorter stack stem or do I need to go an angle set headset and loose the cup. I need to gain another 4mm.

minimum insert of only 22mm, guess that's why its pointing at the ground and not up into the sky
you could use one of these

I have just fitted one to my Circus forks, seems like it might do the trick nicely!

DMR Defy should be 27mm stack height? You won't get much less than that I would think..

I was talking myself into new fork day

Some web sites list them as 27. Unfortunately I found out they are really 31.

yep..DMR is 27mm, that weird looking syntace thing has a stack height of 27mm too but states a min insert of 22mm worst case!

Do you just press into steerer tube?

Alright, let's wrap this thread up folks.

maybe minimum insert of 27mm, but stack height of 31mm

It seems the logical solution, my way of helping our slowing economy

insert slides into top of the steerer once you FO the star nut, then the insert is held in by the long threaded rod and lower insert at the crown end
threaded rod has a threaded hole to screw the stem top cap into to preload the stem and headset bearings

I’m game enough to try this. They do have an interesting clamp to steerer system.

once I get my phone back online, I will get some pics of actual fitment

Older Spank Spike was 24mm. And awful.
Edit. 26mm

I tried to clamp down on my steerer which was too short, and it started to push the steerer walls in on one side!..dont risk it if you don't have enough steerer, unless its Cro-mo or hi ten steel, allow will just fold in and bend as you tighten it more
I tried mine, then wondered why the steering kept coming loose, it was the steerer starting to bend in on the stem!

Did Pole design it?

Some of the stems are chamfered at the edges and they measure from there. I had that with a Ragley. It's annoying!

Oh Lordy that hurts my eyes, it would work though and I have no street cred anyway
