A few questions re: the aerobar
1. Can the extensions be cut?
2. Can the bullhorn basebar be cut out by the brake lever so that they are straight and not flared up?
3. Can different extensions be substituted (say some profile extensions)
4. Can a different aerobar be used on the Shiv S works?
2. I suppose but you wouldn't be left with much.
4. Yes if you also swap the stem; No if you want to use the integrated stem.
