I hope you had a great ride today! Sometimes I think there is no end to the amount of experimentation one can do with one's tire pressure. I can't wait for next winter and we can talk about 3-5 lbs of pressure in your fat-tire bike!
I looked at the two Ortlieb Handlebar Packs and there are many similarities (weight, materials, features) and only a couple of difference I can see:
- The Ortlieb Handlebar Pack - 15 liters on the REI Outlet has a buckle system to attach to your handlebars with a side-release buckle and a ladderlock strap adjuster, in order to tighten it down securely. The Ortlieb Handlebar Pack - 15 liters on REI.com has a side-release buckle with a quick release tab/tightener.
- The REI Outlet model has four smaller foam spacers to dial in the fit to your handlebars, the REI.com model has two bigger spacers.
- The attachment points for the elastic webbing on the dry bag is a bit different.
- It looks like the attachment strap for the stem has a hook and loop closure on the REI Outlet model and a flip-tab clasp on the REI.com model.
The Ortlieb website has a bunch more photos and even a 360° viewer if you'd like to check it out.
Hopefully this helps, let us know what you decide!
@Rob6, I believe Randy Quaid said it best when he said: 'I'm baaaaaaaaaaack!'
