Crank Puller for Campagnolo Power Torque

[GrahamGKD]

I was a bit bored last night so I made this puller to pull the non-drive side crank off my bike.

Thankfully my cranks are aluminum so I don't need to worry about damaging delicate carbon ones.

The plug goes in the end of the hollow spindle once the bolt is removed. The sheet of rubber goes between the tool and the back of the crank to avoid damage.

It seems to work well. I will need to make another tool when the time comes to replace the bearings (if I had been clever maybe I could have come up with a tool to do both jobs!).

Won't mean a lot to anyone who is not into bikes or familiar with campag chainsets but hopefully someone might be interested?

Not something I have a use for but always good to see tools that someone has made to do a particular job.

Nice job. Worth doing if you have got spare time and saves £50 on the park tool. I think the Park tool is the cheapest you can get off the shelf?

What annoys me about all the bike stuff is how they change stuff all the time and in a relatively short time there is no available replacements so you are forced into a complete upgrade on what should be perfectly serviceable parts.

I think the rate of change is increasing as time goes on. I have found J D Whisker to be very helpful in supplying 'obsolete' components in the past, although I haven't found the need to get in touch with them recently.

Nice job Graham!
I've got Ultra Torque on mine so no crank puller needed though the bearings need replacing so I'll probably get a bike shop to do them rather than buy an expensive puller.
I don't have the skills or tools to make one.

Yes it's incredible at the moment the speed of change. On mountain bike stuff I would say it's at the point of ridiculous. I would like a new mountain bike but the amount of possible alternatives at the moment that have come out in the last 2 years is silly and has totally turned me off from the idea.

2 years ago a particular model would be 27/30 gears 26 wheels, last year went to 29 wheels with 20 speed, this year 650 wheels with different gears again. Maybe next year the model will turn into a unicycle.

The MTB crowd can be quite fashion conscious - it's all about the gear for some people. I counted well over 200 logos on my bike once, whereas my Suzuki M50 has maybe 20. Any bike you buy today will still be a great bike in five years time, regardless of what other people are riding.

I like the tool. It reminds me of an alloy cottered crankset I had once (35 years ago...), which was a classic example of mismatched materials. The steel cotter pin would slowly bind with the alloy cranks and we always had to press them out in a vice.
