What if I fail? It’s a question many people ask themselves. A question that often stops us from getting outside our comfort zone. Dan and I planned to bivvy on the Isle of Wight. We failed. For me, failure is simply an opportunity to learn. This is the story of our bikepacking trip.

Is Dan's seatpost still sinking into his frame on rides?

In that story he was on the Genesis iO iD. He has put some of the gritty stuff on the seat post of the Longitude and it seems to be holding now.
