I was going to buy one of these (they come as OE on the new version of my bike so setup would be easy too). Phoned TF, they said what sort of usage, I said, big 29er, everyday riding, some unskilled enduro racing, uk uplift, occasional trips abroad. They said CCDB Inline no use for that job, get a CCDB Air.
I was pretty surprised at that, no ifs no buts, don’t buy this. Even though I think I was pretty clear I couldn’t afford to buy a CCDB Air CS from them but I was ready to buy an Inline right then
