Actually used mine yesterday. Went to the LBS bought a few things. Got a pretty good deal on a Lezyne Mega Drive headlight. 185 discounted to 105. Wife did a little shopping as we were on a trail system. Maybe 10 pounds total. Divided it as evenly as I could between both sides. I didn't have any issues with weight shifting,or as I have read that some have said they brushed the bags with their heels. I'd have to have pretty dang long feet to touch the front of the bags. I'm thinking my wife and I will find the weight limit I can pedal with. I like it so far and I think it looks pretty cool too.
