my angles arent steep (i think 73.5->74 for both) but i have a saddle->bar drop and i don't like it much.
not that im not flexible or anything, because i can rock it on a normal road set up.
however, on the fixie--without brake hoods to lean on; having my ass high up and forward; and having to constantly spin--its nervous riding downhill... bumps on the road tend to jolt me a bit upwards (out of saddle) and i have this unsettling feeling ill soon get tossed over the front-end from hitting a random bump or a big crack...
maybe ill get some tires with much more volume
