I bought and renovated this Cannondale Rush SL 4 last Fall, put about 5 miles on it, and then bought another bike I'd been stalking for years. Reluctantly selling to make room in the garage. Size XL frame. Handmade in the USA.

Stock Components
Lefty Titanium 80mm suspension fork (upgraded from the original Lefty by the previous owner)
Fox RP23 rear shock (I think this is also upgraded, as the bike was spec'd with an RP2)
Mavic Crossmax wheels with Maxxis Ardent 26x2.25 tires, tubeless
Avid Juicy hydraulic disc brakes

2017 Upgrades
SRAM X0 1x carbon crank 175mm
SRAM X0 9-speed twist-shifter
SRAM X0 carbon cage rear derailleur
Absolute Black 34t direct fit oval narrow-wide chainring
SRAM PC-1071 hollow pin 10 Speed chain
SunRace 11-40 9-speed casette
Jagwire Mountain Elite sealed shifter cable
Titanium bolts all over

Upgrades were all either brand new or in excellent condition - only the crank shows signs of use. Everything works like it should, suspension is smooth and did not leak air while stored for the winter.

There is a lot of Ti and CF on this bike. It weighs just under 24 lbs with heavy platform pedals pedals (which are not included in the sale).

If 1x9 is not enough gearing for you, I have 2x and 3x crankset options, XO 1x10, or a full XT M8000 1x11 setup we can discuss. I also have other Lefty stems if you want a different fit or bar diameter.
