i just finished a lengthy tour in reasonable comfort using a 90mm/115degree thompson elite stem holding my moustache bars on my surly crosscheck. my steer tube is completely uncut, so the bar height is at maximum. i still want to get them up and back a little more, but i feel that if i just get a shorter stem, i'll lose too much height.
are there any stems out there with steeper angles that aren't of poor quality? (dimension)
are clamp-on style steer-tube extenders reliable and strong enough for fully loaded abuse?
any suggestions would be great.
