Giant TCX saddle clamp bolt size?
Hi,
I have a Giant TCX Advanced Pro 2 with a carbon D-fuse seat post. I need to adjust my saddle after it shifted going over a bump, but found that none of my Hex wrenches fit the saddle clamp bolt.
Does anyone know if this is a Torx or Hex bolt? - mine seems to be rather chewed up and it's difficult to tell.
The bolt head is much bigger than a Torx T-25, but seems too small for a 5mm Allen key. 4mm keys are also too small, so it seems to be something in between which is very odd!
I think in the past I had used a larger Torx head (T30?) - but can't recall.
Can anyone help?
Thanks!

Thanks. Ths T30 fits quite well, which is why I’m wondering whether it *is* actually a T30 bolt originally. It just seems an odd choice if it is true. Normally they are 5mm bolts, right?
