The 'clean' ahead stem thread - a collection of ahead stems that resemble classic quill stems

So steel stems & alloy spacers aren’t the same thickness - where can we get pieces steel spacer from, stainless so paint not necessary, in long sections for scoblestack goals? Framebuilders?

The OG Deda Zero

ITM Moray

Might be interested. Do they happen to 1 inch steerer?

Guess some framebuilders might have stainless in stock in the same wall thickness you'd build a stem from but I can't really see why.

I use tubing with a .058" wall thickness to build steerer clamps for stems so its a lot heavier than frame tubing.

Ricky Feather, had the top cap as part of it, it was plated after this but I don't have any pics of it around at the moment:

Edit: found one of it finished.

I've only found suitable steel spacers made by Nitto and impossible to get hold of here. Titanium alloy spacers are the same 31.8 OD, cheaper, and readily available on eBay, which is just silly.

I hope ITM paid some royalties to H R Geiger for that design

.058"

That’s just a mind-bending anachro-number, what does it mean?! Nearly 6/10ths of an inch... I’m see what you’re saying: normal tubing could look too thin to marry up with a stem clamp... but I’d guess not as bad looking as massive thick alloy ones do.

Yeah I’d seen the nitto ones. Might hit up bluelug or alex’s and just swallow the shipping and customs :/

Also August Bicycles are doing nice things with stems (and spacers with bevelled bottoms) ...

Nitto spacer group buy?

Easier if you convert to mm?

It’s about 1.5mm. Frame tubing would generally be around 0.8ish mm at the heaviest.

Thinking about it actually, the od would be easy enough to match but it’d have the wrong id so would be a loose fit on the steerer.

He does some fine work Ricky.

Pretty sure I’ve got inch and 1 1/8th, will confirm later

Rob english great design on a removable front plate for over sized bars. Craftsmanship and engineering excellence combined

I guess the real solution to the space issue is to have a stem custom made with the stack height you require and then you don’t need spacers.

Or maybe these,

Yep, re: stem. It was just those pics from bluelug of custom spacers got me asking, I have ahead bullmooses that look weird with my alloy scoblestack. Sorry to derail.

Back to the stems!

The ricky feather is really nice, especially the position of the front bolt - but looks like a custom made thing that will be $$$expensive

I really wonder why there is no combination of the Syncros or Schindelhauer "central bolt" and a front end like on the Nitto CT81 or even better the ricky feather, all done as an affordable mass production item

that will be $$expensive

You get what you pay for, he's not prohibitively expensive though.

That’s just a mind-bending anachro-number, what does it mean?! Nearly 6/10ths of an inch...

you just say 'fifty eight thou'. american engineering types still use thousandths of an inch as a reasonably precise unit of measurement for things in areas like machining on lathes and so on. confusingly, they call ten-thousandths of an inch 'tenths'.

roughly 40 thou is a millimetre, so yeah 58 thou is 1.5mm near enough

Had the same problem a few years ago after putting a Cinelli Grammo on my Sarto, played around with stem heights with poor OD of spacer to OD of stem match... have access to lathes so machined down some thick wall tube (or possibly solid bar?) to get it to fit. In the end I had aluminium headset / stainless spacer / Ti stem / stainless spacer / Ti headcap.. surprising the difference in colour of each material even after polishing.

It worked nicely though

Beautiful! I asked Ricky for a price but at that point in time I could not justify the expense. He is an artistic genius though!

This is a nice vid (if it works)
