TLDR- Anyone have/had a Rush and have an opinion of it?

I picked up a alu langster frame recently for an embarrassingly low price and it’s been great for all the hill climbing I do. Pretty light, ok clearance and carbon fork make for a solid climber and a comfortable enough ride on tarmac (way less bone jarring than my ‘88 cannondale).

But very often my path intersects with a railtrail that is mostly hardpack and crushed stone dust and sometimes I like to cut through to break up a ride. I’ve ridden through a few times on the langster and it’s been...ok, not great. There are sections that are bone jarring (can’t see straight!) and others where there are no issues at all.

So I’ve been thinking of adding another frame that would be better able to pull double duty and a Rush popped up locally for a hard to pass up price. The Rush was the first fixed frame I was ever really interested in but I went a different way in the end.

Ideally, I would grab a Wabi or a steamroller but I do loves a deal! I know of the the three, the Rush is more aggressive and least ideally suited to a lil off-roading, but I’m not riding gravel and not riding trail aggressively, like at all.

So, my biggest concern is basically inexperience. I’ve not riden a frame with a seat tube angle steeper than 74.3 and the rush goes 1 degreee steeper. I’m not sure how this will impact my riding position over terrain.

Am I crazy to consider this or should I just man up and grab a lilac steamroller?
