Some newer alloy stems are incredibly light but even if it''s a tad heavier I like the integration of hanger, spacer and the fact that it''s handmade from steel.

You can see the tiny rings of brass in the photo of the top of the steerer extension. I don''t feel like there is enough surface area if the hanger is just brazed under the extension. I''ve been putting off building stems for a long time because I didn''t have time to build a jig first. I just wanted to get this one done, and Alistair pointed out that going jig-free would probably be fine since I can get very accurate miters on the milling machine. I do measure things that matter (like tire clearance and frame alignment) very accurately, but I''m pretty fuzzy about some other stuff. For instance I don''t think I''ve ever measured the actual C-C seat tube distance on Gifford. It doesn''t really matter too much where the top tube intersected the seat tube, having accurate miters and something that looked right was more important than having exactly a 5 degree sloping top tube.

Also: "I did this one jigless...." "not measured precisely..." Are you sure you aren''t Alex''s evil twin? Doesn''t sound like the Alex I know. “the cable hanger fully pierces the top and bottom of the stem”
