Holes in carbon forks

Postby orangebiker » 25 Aug 2014, 9:45pm

Just bought a new carbon road bike and noticed that there is are 2 small holes in the forks, one on each side, on the inside, about 2 inches from the hub. Have only ridden it for a couple of miles so I doubt that I have caused the damage especially as the location of the holes is symmetrical - although the shape is different. One is about 2 mm across and is quite deep and jagged. The other is smaller and is regular shaped. Not like a chip. Can't see anything similar on any other carbon forks in the house. Although the holes don't look like they would cause a danger at present, I'm a bit concerned they could indicate a fault in the manufacture and could get worse - probably going to take it back to the shop. Has anyone seen anything like this before?

(Not impressed anyway as the forks nearly fell off after 2 miles - headset hadn't been screwed together properly in the shop. Also there's a clanking from the bottom bracket. Call me old fashioned but I expect to get a usable bike for £1400 and not just something that looks nice....)

Jagged holes in carbon are scary. I'd holler.
Have we got time for another cuppa?

A shortcut has to be a challenge, otherwise it would just be the way. No situation is so dire that panic cannot make it worse.
There are two kinds of people in this world: those can extrapolate from incomplete data.

I'd take those forks straight back!

How is the bracket for the front mech held onto the seat tube?
Is it pop rivetted?

That will give a clue to the manufacturer and shop you bought the bike.

Right hand side
Left hand side

It's a cube bike which I believe is a good make.

If the two holes are in similar positions then possibly they were part of manufacture.
If you can, go back to shop and check against other Cube bikes.
You'll never know if you don't try it.
