I ran the bike with an Ohlins TTX Coil shock and it worked really well. — Hope Seat clamp. — Hope Headset. If you run a 210x55mm rear shock with the shock plates in the lower position, you’ll have a nice 140mm trail bike, or you can run a 230x65mm rear shock with the shock plates in the upper position (as I did) and you’ll have 165mm of single pivot travel to play with.
