When I started commuting in London in the seventies suits were required at work. I found that decent trousers and saddles didn't work well together. I quickly destroyed several expensive trousers whilst the jackets were just fine.
So reverse it. Wear the jacket, tie and shirt and some cheap trousers or thin lycra tights and do a quick swop in the loo before going up to the office. Both can roll up tight and suit trousers carefully folded don't completely destroy the crease.
Or do as I eventually did so it didn't matter if it rained or I got a bit sweaty - find some locker space and go completely lycra and do a Clark Kent!
