OK, for balance, the Giant has a pretty “old school” geometry, weird proprietary junk like the steerer size and a wheel size suited to the more midgety types
The Sensa is almost unknown here in the UK, probably an open mold frame with better spec and the geometry/ fit is a mystery. Again prefect wheel size if petite
The Saracen is an average spec, more “trail” geometry (where the smaller wheels are clearly acceptable) but every where you go people will say “mate, ur bike iz well sarasin”!
The Yeti is a nicer bike and will handle everything from bimbling to racing to trail mincing but at double price… and will probably crack
That is the probably most of the negative stuff you could expect to hear on STW so I thought I’d get that out of the way for you 🙂
Personally I’d be looking at the Scott Scale, Cannondale F-Si, Trek Superfly ranges
