I ride a rigid steel mountain bike in gravel bike guise (so a fair bit of on road riding) which I use for lots of totally unskilled riding about.
The grips are a couple of CM lower that the saddle giving a decent attack position and this has worked well in all situations.
Recently though I’ve started getting a bit of neck pain (it’s probably just age, I’ll be 50 at the end of the year) and I’m wondering about just nudging the ride position up a bit.
The obvious solution would simply be to raise the bars slightly but I could also shorten the reach a little instead.
I’ve never really understood the finer points of geometry, I just tweak things until they feel about right so I’m not sure what to expect from a shorter stem (although short stems seem to be in fashion).
I’m currently riding an 80mm 0? rise stem and a 5mm riser bar (so almost flat). What would I notice if I bought a 70mm stem?
