Stand over clearance, how much/little?

[RockiMtn]

Looking at a new acquisition, bike is a tad taller than any I currently own. I don't actually have the bike in hand to do a proper check, but guestimating I may have about 1" stand over clearance with it, I usually go roughly 2" or more.

What's your preference in how much room to give your crown jewels to keep them safe???

I used to tell people to take 13 inches from the inside leg measurement to gauge frame size for off road but I wouldn't be happy with just an inch clearance no.

13"??? :?

So say I'm a 30" inseam, minus 13" so that leaves me 17". so what's that represent?

That represents the suggested frame size. Not sure it that's C-C or C-T though. I have a 32" inseam and generally find that 18-19" C-T frames suit me just fine.

That being said, there's a huge difference in standover between an old 19" and a modern one, mostly because the headtubes on modern bikes are on average 4" higher than in the old days.
On my modern, I have 1" as well, whereas on a 19" retro I have 3" standover clearance.

Mossy, stop trolling RB and get on that Cirrus and finish it already! :roll:

C-T, is that top of tup tube junction with seat tube right? as BB centre to top of seat tube would vary depending frame design with how long the seat tube is extended. Either way, I've been given 16.5" C-T top tube junction and 18.5" C-T top of seat tube, respectively at the moment. And this is a retro bike, otherwise I wouldn't have posted in this section.

Maybe I gotta go check my clearance on the largest bike I have, perhaps I have more clearance than I think I do.

Yes frame size is what I was referring to but it was a guide as we measured frames from the centre of the bb to the centre of the seat post binder. Obviously this was subject to difference with the likes of kona whose binder could be 2 inches taller that the top tube but I would never have recommend a stand over height of less than 2 inches regardless of measurements. That said the reach will work out shorter/longer as well so factor that in.

Well Centre to top of seat tube is your standard frame measurement (for most the bikes you have)
buggered if i'm going to ride 21" bike's.

If you're worried it'll not fit, you can always pass it this way if it's anything like a thunderbolt or tantalus or similar
OR
Turn it into a commuter, road, canal path sort of bike. You might find the higher front end and stretched out position a bit comfier. Assuming it's bigger in all directions to what you are used to.

It was only seems higher on the Kona as the top tube dropped away from it's horizontal position. Same for Rockies ...
Marin, GT didn't really slope so it was never an issue with them.

Orange on the other hand...

Yes indeed, the sloping top tube I'd forgotten about
