For me, Noodles have the best of all worlds.
- the nice flat ramps (the spot behind the brake lever) of a ergo bar. This is priority #1 for me 'cause I spend alot of time here.
- a tiny bit of sweepback on the tops to match your wrist angle on the tops, like a rando bar, but without being really narrow or having a flare at the ends
- really damn wide if you want it (mine are 48cm) like an ergo bar
- comfy and flexible drops like a traditional bar
- old-school polished look with an engraved crest like a traditional bar
- pretty light (for the Soba) or really strong (the Noodle)
I wanted flat ramps and traditional drops and the Noodle/Soba was the only bar I could find. I went with a 48cm on a whim 'cause I'm all about wide bars on all my bikes (except dirt jumpers) and am stoked.
Now I want another Noodle for my touring bike, a Soba for my race bike, and...
Edit: Oh, I use 8-sp DA STI, and switched from Cinelli 66's which are nice, but don't have the flat ramp.
