I like the idea of having 13 teeth on the smallest cog, rather than 14.
Yes you will be able to straight swap those.

What is the stack height on this?

I'm refurbishing a '69 Mercian. I've had the frame spread to 130 and now need to upgrade the transmission onto NOS Campag l/f record screw on hubs, currently running 13/24t 31mm 6sp-freewheel. I want to upgrade to 7sp with 28t. Will this item suit? Also which chain should I use?
Hi there,

The total overally is roughly 34.6mm.
You can use most 3/32 6/7/8spd Shimano chains.
