My current adventure setup and some changes

This is my current adventure bike setup. It's an aluminum Motobecane Outcast29 single speed with WTB dirt drop bars. I have the gear set to 32 x 16 freewheel and 14 tooth fixed on the flip side.
So far the 32 x 16 is working ok for most climbs I've been riding, if it gets to steep I walk. On the flats I'd like a little more top speed without working so hard but that's the trade off when single speeding.
The main problem I'm having with this bike is that the frame is harsh after about 30 miles. My lower back is taking the most beating so I'm thinking about changing over to a steel frame and a dingle setup. Something like 34 x 16 and 32 x 18 or 20 just need to experiment with chain length to see what matches up ok. I'll run a skewer in the rear axle so all I need to do is release the skewer and move the chain over. Go fast gear for the long road sections and a good climbing gear for the steep.
I plan to keep the drop bars and On One steel fork. Currently running V brakes but will change over to BB7 disc.
I should have everything changed over by the weekend then out for some test rides.
