Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Mystery holes



This "Ex Mario Cippolini Time Trial Cannondale frame" was recently posted on FGG.

What's the deal with the holes drilled into the side of the seat tube? (as easily seen in this picture)


(p.s. the image links to the post on FGG)

It's a time trial frame, so it's made for road, not track. Hence, the road geometry.

I understand the TT aspect and why the holes are there, but what I don't get is the lack of derailleur hanger in the rear. And the dropouts/trackends don't appear to be replaceable.

It's something you could do, but on that bike? I'm not so sure it would designed for a low-end form of derailleur attachment.

And it's hard to tell, but that brake bridge doesn't appear to be drilled.

It's probably a road frame that they just welded track ends onto rather than designing a whole new fixed specific frame without the unnecessaries.

those are "speed holes". They make you go faster.

I was wondering when "speed holes" would be mentioned.

He may have taken a saw to it to make it look like a track bike. The brake bridge is a mystery though.

They just used a seat tube that already had the derailleur holes in it. That's why it does not go along with the track ends.
