Interesting. I'm planning a soma demi porteur rack and a rack bag, with a roller bearing headset as the reports of whole bike shimmy on the rim brake models were a bit concerning. Apparently, the disc model lengthened the trail slightly and a roller bearing headset helps. The low rider panniers looks great.
what wheels/tires? those are 650x48c. i went from a 650x42 to that because the 42c were defective (the entire lot - they sent me 4 replacements). Despite the casing being wobbly, i recall much less shimmy. i'd recommend - if going 650 b - to use a 42.
all this aside - great bike. One of my favorites i've owned. I just think it gets a little moody when putting weight above and in front of the axel.
So I've put 30 miles on the Soma since changing the rack to the lowrider - the bike is transformed. I'm really surprised by how negatively that larger rack affected the bike's handle low speed no hands tracking. Much better now. No notable shimmy anymore, either.
