Head tube reaming on a new frame

[retroJIM]

Hi all,

I've bought a brand new frame set and the bottom bracket has been chased and faced as well as the top tube. However when fitting the top headset cup (zs44) it was an extremely tight fit. So tight in fact that the bearings don't fit into the race when the cups are installed in the frame.

I think this may be because the head tube is slightly ovalised. So my question is should I take it to my lbs to be reamed (assuming they have the tools) or should it be sorted by the manufacturer?

I'd take it back to where you bought it from as it should be up to them to sort if defective.

I'd be surprised you could fit the bearings to the point they deform and stop the crown race fitting, I'd worry the frame would crack at the head tube if they are that tight.

Good luck sorting it whatever route you take.
