About brakes...I run a front brake on my fixed..I hardly ever use it, but I've HAD to use it enough in emergencies to realize that running brakeless is really stupid. the 925 has brakes..thats great, keep em on there, at least the front.

about clipless pedals...Oddly enough, the first time I started riding fixed was also the first time I started riding with clipless pedals. At first i thought this would be suicide...trying out riding fixed and clipless at the same time. But I found that snapping in and out of clipless pedals with the cranks moving is not that hard. You just have to remeber to twist your foot sideways when you come to a stop. It became natural after a ride or two, along with the whole fixed experience. I've never tried it, but I'd bet that riding fixed with with clips and straps is harder.
