Picked this up, very stiff frame (I love that), and amazingly light. It's easily as stiff as my Fuji Track Comp was, but much lighter with a full Dura-Ace 7800 groupset on it!!!

Bottom Bracket...

Just curious if your Klein had the press fit BB and how you installed the Dura Ace Crank?


They were all press fit, but the way to convert to modern bb's is to ream and face the shell to the correct size.

This was done by the previous owner though.

I can ask him what he did though!


nice ride. always had a thing for Klein's, not sure aluminum gets any nicer than them. like the bar angle/shifter positioning (how it's flat the whole way across) you don't find it too stretched out?

Hi, Yeah, this is a joy to

Hi, Yeah, this is a joy to ride.

The bars were a bit too stretched out for me, so I have converted it to take a standard 1 1/8th stem and bought a modern short reach/shallow drop set of bars which I am currently loving.

These ITM's were the dogs balls back in the day, just over 200g and modern deep shape, perfect for race day, but I find as they are 25.4mm they flex a lot. My new bars are super stiff, but about 300g. I would like carbon bars, but at 10x the cost, I can't justify it at the moment.


I like your setup, how are the spinnergys, im looking for a new wheelset but i am scared carbon spoked wheels will not be durable

This is my second set of

This is my second set of spinergys, I like them. Some people hate them though because the early gen models had a bad rep for ass'ploding.

I do treat my bike very carefully not to drop or damage it. The Carbon blades are very strong but easy to take chunks out of if hit by something so I don't lock my bike up around other bikes, and hang it up inside when at home.

My last set I did leave in a public bike park and it did get hit by other people's bikes as they put them away and had a little chunk taken out. But Spinergy say it's fine and I sealed the exposed strands of carbon with nail polish and it was fine.

But I generally like to take care of my bikes more than the average person.
