Just put my '07 DB Response back together after a pretty hefty rebuild. Its now a 1x9. Fun build. I'll get a new fork this summer too.
Used Deore crank (Granny delete)
N-gear JumpStop chain stop
X7 shifter and derallieur
SRAM PG-980 9-spd cassette
Avid FR-5 brake levers
bb7 brake sets
And a little vinyl, just for funsies when I was done...
If anybody wants to see more, just ask.
