What SLUGS they were! They made the 26x1.50" on my "grocery getter" seen like race tires.
I couldn't believe how a "street" tread could be such a pig. Heavy to accelerate and I had to work my butt off to maintain speed.

You should be able to go as small as 25-26MM without issue.
The difference will amaze you. Even a 28MM (1.125") will be "fab"!
