I put the Tubus lowrider on my troll. There was room for a surly eight pack rack on top. It looks cool. I almost bought the wider 24 pack rack but my current troll is set up for my street and bike trail rides, and I didn’t want that big of a front rack. The 8 pack will hold my small cooler for longer rides. The 24 pack rack would hold my tool bag well for a work bike.
I like the set up. It could hold tools and small amounts of material well.
I just need to figure out if I really need tires bigger than 3” wide. If I don’t, I’m buying another troll.
