Ed - the tires are Rene Herse Umtanum 650x55, wrapped in Simworks Flat 65 fenders. It's a good combination, the Susie has plenty of extra clearance but this maxes out what I can fit under V-brakes. Without fenders I'd be comfortable with a 2.5 to 2.6 with V-brakes. The Motolites are nice to set up, you can just install the pads to be parallel the rim, and then use the 'collar' to adjust up-down as well as fine tune the toe-in rather than try to set all these at the same time using the cup and cone washers. I appreciated that the Susie's studs were spaced appropriately for the Cliffhanger rims as well
Brendon - I'll probably bring the bars down a bit, but yes since I'm on the 50 despite being able to fit a 53 easily I've got a bit less stack which is good! I can bring them down to basically level with the saddle if I want to.
Richard (and also Brendon) - I can definitely see moving away from the Ortho bar for singletrack. I have a Stooge for trail riding as well as the Crust Wombat, so my off-road needs are fully met between those two and I love them both. It begs the question, isn't the Susie more bike than I need if my purpose for it is commuting, cruising around town, and just a bit of gravel and trail riding? So far I'm really enjoying it for these purposes, but it'll be interesting to go back and forth with the Bombadil and compare. Bombadil is obviously stiffer and more compact, both super capable.
