The frame is only 2 months old. I rode it 4 times in BP in 7 days; after that, I decided I would just go in another direction. The bike has scratches from transport on the top and down from a loose chain, you can see this in the photo. The rear axle is 148/12, wheel 29. The headset comes with the frame; the lower one is Cane Creek (for better reliability), the upper is Acros. I can add a Super Deluxe Select Plus shock for 100 EUR or a Deluxe Select Plus for 55 EUR; the diameter is 205x60. The frame is still under a 2-year warranty; I have a receipt for it.
