Seat Tube Diameter


Recommended Posts


Anybody know what the lower outer seat tube diameter is on a Giant TCR Composite (T-Mobile).?

I forgot to check but want to pick up a "Dog Fang" sometime today.

Can't find anything on the net either.

I know the seatpost is 27.2mm, so I'm thinking ?31.8mm ... but it could also be closer to the larger 34.9mm


Let me know, thanks.

Thanks.! You've hopefully saved me a trip home.

And that is the outer diameter around/just below the FD area..?
