PRODUCT SUMMARY

The S.I.R. 9 is the most versatile bike in the Niner stable.
The S.I.R. 9 uses the same custom drawn Reynolds 853 tubing as the M.C.R. 9 and combines it with Niner’s ultra-light eccentric bottom bracket. This legendary frame material provides the best overall steel ride one can buy - smooth, responsive, strong, and light - you are looking at a frame that will provide many miles of great rides
Custom “breezer” style forged dropouts have a replaceable alloy derailleur hanger and come with an insert piece for running the bike as a single speed to eliminate the unnecessary derailleur hanger for a clean look.
Niner’s own EBB, at 100 grams, is the lightest eccentric bottom bracket on the market. In addition to being light, it’s extremely functional.
The EBB has more swing than any other EBB, over a full link, so you will never have to hunt down a half link to get correct chain tension and vertical dropouts mean you’ll never have to futz with the disc brake to remove the wheel.
Frame geometry is optimized for 80-100mm travel suspension forks or rigid forks
Disc brake only
73mm bottom bracket width
27.2mm seatpost size (29.6mm seat collar size)
28.6mm front derailleur, low-mount, top swing, bottom pull (When using a front derailleur with this frame the Bio-Centric bottom bracket should be in the 3 o'clock position.)
Uses standard 1.125" (1-1/8") external bearing headset (not included)
Replaceable rear derailleur hanger and singlespeed insert included
135mm QR rear spacing
Can fit up to 2.4" tire (tire size varies by brand, some tires may not fit)
Compatible with current-standard 3x chainring systems
Compatible with 2x systems from SRAM and Shimano, however certain sizes will not fit. We recommend using the following configurations: SRAM recommended 2x setup is 26/39t or lower, Shimano recommended 2x setup is 28/40 or lower
This frame uses the Niner EBB (bottom bracket) which is designed to be used with external bearing cranksets (and bottom brackets) only
The S.I.R. 9 is truly a do-everything frame. Run it single speed at your local race, then convert it to a full gear set to do the Trans-Alp. Want a 1 x 9? No problem. Or, if you’re just not sure, the S.I.R. 9 will give you the option of trying it all.
Are you also looking for a build kit, wheels, or front suspension fork with this frame? Call 1-800-820-GEAR (4327) for additional details. We have Shimano and SRAM build kit options available.
