thumpism — I can't get mine mounted quite as low as yours due to the RD cable being routed along the top of the chainstay. I have the FD as low as it can go while clearing the shifter cable. It's reassuring to know the jumps shouldn't be a problem. It's too late to tinker today, but I'll get to it tomorrow or Wednesday.
I'm realizing I failed to mention it's friction shifting using Suntour Barcons.
