To accompany the Redline Mono 9 bikes I have, I got in a few single-speed Monocog Flight 29 bikes. Very nicely appointed single-speed 29" wheel bike.
Monocog Flight 29
Reinforced head tube and bomber down tube gusset that clears suspension fork knobs.
Good tire clearance for the fattest 29" tires.
Sliding dropouts. The frame also has full cable stops/guides so it can be turned into a geared bike with the appropriate slider.
Clean design on the seat stay bridge. Slot for the seat post faces forward to keep crud out of the seat tube.
Time to get your 29er on.
