DEDa seat clamp bolt size

[stumpy66]

Ive managed to round off the bolt for the seat clamp part of my seatpost and have since stupidly misplaced it, does anyone know the size of the bolt i need, m6/7 or 8 x ??mm

It's a rsx 01 seat post

It should be easy to measure if you have a vernier, which I assume you don't? In that case, we'll give you some clues.
1) M7 doesn't exist other than in some special cases, so you can rule that out.
2) M6 is too thin for a single bolt system and is usually used in pairs.
3) M8 is strong enough for a single bolt system.
4) Stainless steel bolts are not strong enough for seat clamp use. It should be high tensile.
5) The bolts in question are technically called socket cap screws or just "cap screws".

Having said that, can't you just buy one of each? A spare bolt is hardly going to break the bank and will come in handy at some stage.

The saddle clamp bolt on my Genesis takes a 6mm allen key and my Verenti takes a 5mm allen key. I think thats M8 M6

Now there's a nice clue! OP, what size allen key did you use to violate that bolt?

I would say its most likely be a 6mm allen key.

Yeah it was a 6mm Allen key, so should I get a m8 hi tensile bolt?
