It hasn't arrived yet. Delivery scheduled for today. I still need to get the shock mount gear and swap the air shaft in my Reba to increase it to 120mm.
Intriguing. Thinking about morphing my 27.5+ Sentier into something a bit more XC oriented, even pedalling three miles to Leigh Woods is a real drag on it.
Got any pics of the build? Assuming you are running it 29.
