Niner SIR9 Small New 1x10 drivetrain. Complete bike or can part out.


Well-Known Member
New Price - $600 for the complete bike.

I'm open to breaking it up as well. Frame, fork and headset for $300.

Up for sale is my Niner SIR9 – Size small in Godzilla green. 853 steel frame with EBB in really nice shape. Chris King headset. This was my single speed ride for a couple of years, but I have moved on and this mostly hung in the garage. Need to make room.

This frame rides great. The steel really soaks up the bumps. Fork is a Rockshox Reba set at 80mm with poplock.

I have just refreshed the drivetrain for the sale. It is now built as a 1x10 with an all new drivetrain including a Sunrace 11-40 cassette, Sram chain, SLX shifter, Cane Creek Cobalt bottom bracket. Wolftooth N/W 30T ring to complete the 1x10 set up (now complete). The mechanical brakes have been replaced with a set of Avid Elixir R’s (used and need a bleed).

Other components include:
New Lock-on grips
On-One Mary bars
Salsa Delgado rims on XT hubs
XT rear derailleur
Maxxis Ignitor tires
Orign 8 seatpost
Raceface Turbine cranks
WTB Saddle (black, not the one shown in the pics)

Easily converts back to single speed. This would make a great bike for a smaller rider. Have a young rider racing NICA this year?

Asking $600 obo.

damn I wish I could pull the trigger on this. It's exactly what I'm looking for.
Do you have an updated list on the parts you're going to part out?

Throwing some prices out there:
Wheelset - $75
Fork - $100
Mary Bar - $20
CK headset - $60

I may keep drivetrain for another project.
Heh, I didn't even notice you had alt bars on in the original for sale ad. I had a set of Crivitz bars I've been waiting for the right bike to put them on. Just finished putting it all together.
