Since we all know low bars are for noobs, I thought I'd post of pics of my recent project, a spacer for my 888 direct mount stem. Just made it out of 1/4 aluminum stock I ordered from McMaster. I'm a VERY noob machinist, plus lazy and impatient, so I just made it the easiest way possible. It brings my bar heigh to 43.6", and with a 14" BB height that becomes a pretty tall stack height. I'm debating if I should make another one and increase the bar height another 1/4. I'd have to get new bolts then as well.

Almost done

Done-ish

And because I know it gets you all wet, 16g

Installation in progress

Installed

Another angle

And a final angle.

you should make it out of titanium

looks nice!

 

[juanbeegas]

Other than because you can do it, what advantages does that have over just running spacers beneath the crown?

Look at his crown. There's no room to go higher.

 

[juanbeegas]

Aah... I missed that pic, it wasn't loading when I posted.

 

[ridiculous]

Very cool. I wish I had my own mill.

 

[nelsonjm]

Nice, did you drill out/tap the holes with the mill too (cnc setup) or do that on a drill press?

Maybe you were joking, but if you weren't, I want to be the annoying person that points out that that'd be heavier

 

[captainspauldin]

Nice! Wouldn't mind one or two of these for a boxxer dm.. The 2010 boxxer high crowns don't seem as high as the 32mm boxxer crowns..

You know, if you removed that spacer from under your stem, you could save 16g.

Just sayin.

I'm very confused.

That stem doesn't appear to be a direct mount? How does it mount to the plate and in turn to the top crown? And it mounts with only two bolts? The idea (your idea, not Answer's) seems great but the execution seems odd to me.... With only two bolts mounting to the top crown it seems like there would be alot of bending stress on those two mounting points when you got over your front end. Maybe I'm not seeing it, but that stem just seems like its causing you more problems than helping (hence the need for a spacer).

*edit* your last two pictures aren't showing up for me.

thats how Marz does their direct mount stem. you can see the holes for the stem on the crown (the stem is 180* in the pic.) that looks like a Azonic stem too

I gotcha now... The bolt heads are on the underside of the crown and thread up into the stem. So you guys running Marz direct mounts (with only the two bolts and steerer tube pinch bolt) haven't had any issues with flex? Seems like an odd design to me...

yes, bolts heads are under the crown. ive never noticed any flex what so ever on either of the forks ive had and havent heard of anyone complain about it.

Just a 3/8 end mill bit and a 15/64 drill bit on a manual milling machine. No CNC for me, that'd be too advanced. The holes aren't tapped, the bolts just slide through.

Yep, 2 bolts, and it is an azonic stem. It's the only flashy 888 style stem I could find. Dreadfully heavy though.

Flex? Negative. Yeah its a weird design, but remember 2 bolts directly mounted onto the crown is still plenty of clamping force. Plus you can see the stem also has 2 6mm bolts clamping to the steerer like a normal stem.

Now I just need to find somewhere cheap to anodize it!

 

[kidwithbike]

captainspauldin, I will make one for you, if you walk the 2 blocks and deliver beers to my apartment.
we will find some Al scrap and mess around making it in the machine shop at my work.

I used a LaBatts can for a shim once. Some people thought that was amazing.

Thom keep quiet. I checked your bike, and its 18g too heavy. HACK.

Clearly you haven't seen me race (watch till the end, keep the sound on).

It's my breakout year I can feel it.

Hmm I do have an extra low crown we could use as a template..

It's the excess weight of the sharpie on my tires!

ok screw that. make a mold for a carbon one instead.
