stem angle and steerer tube length(4 posts)

To get the bars in to the correct height it's possible to have a short steer tube and a stem with a slight rise, or to have a longer steer tube and a stem with negative rise. I know many opt for the negative rise stem out of respect for traditional asthetics; however, does it really make a difference in performance? It seems that the shorter steer tube would be ever so slightly lighter, and possibly be a bit more rigid? Which is the better set-up, or does it matter?
no spacers, thanks....C-40

I carefully select the head tube length and stem angle that will produce the bar height than I want without spacers. This approach is both lighter and more rigid. I'm able to get this height with an 80 or 84 degree stem. Of course it helps if you can tolerate an 8-10cm difference between the saddle and the bars.

If you need more than a 90 degree stem, you're liable to catch grief from fellow roadies for adopting the MTB look.
right on, the 90 Profile Designs look good.sievers11

If you cut the steerer tube shorter, it will be lighter and stiffer. However, once you cut that tube you can't go back. If you find that you need to raise your bars more, you'll either need to get a higher rise stem or buy a whole new fork. I initially hated the look of riser stems, but I'm starting to get used to them. They still don't look as graceful and sleek to me as a nice threaded 73-degree stem, but they have a certain no-frills utilitarian charm. Take a look at the bike photos on the www.steelmancycles.com web site. Steelman makes some of the nicest frames around, IMHO, and I think they look great even with riser stems, spacers and extended headtubes. My Gios has a Salsa SUL 105 stem with about 3 cm of spacers. At first I really hated the look, but it's kind of grown on me and now I think it's sort of cute in a funky way. However, I would have preferred a nice polished aluminum threaded stem had that been an option.
