Wouldn't it make more sense to get in touch with your national governing body - http://en.wikipedia.org/wiki/Pakistan_C ... Federation

Alternatively, the nearest Cannondale importer is in India - http://www.cannondale.com/nor/distribut ... rnational/ - that's got to be a better bet than asking on here.

I have searched on the internet about the problem and it looks like it has a faulty bearing. Also the machined part of the crank spindle which contacts the bearing is faulty and not the exact diameter because of which there is a play.

was it new? if it's two weeks old, it seems much more likely that it has been poorly assembled

remove the cranks, you should be able to remove the bearings without special tools, just be gentle tapping them out, then grease the bearings, the bearing seats and the spindle

you can refit the bearings using a large nut+bolt and some washers the correct size, it works fine this way, a decent mechanic in a local garage can probably help you do all the above

I did contact the officials from the cycling federation. Apparently I have the most advanced bike here. All other riders ride old bikes with standard BB.

It was 4 months old. I bought it from a Indonasian guy. It worked well with him.
But with me, my team train really hard and we climb alot too.

I did remove the crank and greased the bearing but clearly I can feel the friction in the bearings. Further more the misfit of the crank spindle is quite visible. I had fitted a aluminium foil between the bearing and spindle to remove the clearance, it worked for only a few days.

The tools are very important because its very delicate work and can cause permanent damage to the frame otherwise which is the last thing I need.

I feel for you, but the forum has some rules and one of them is not to open a million threads about the same topic or you will be treated as a spammer.
I have erased the other ones and left this one on.

This has a nigerian feel about it ...

I'm just impressed he's specified the park tool option rather than a cheaper one...

There's no substitute for quality - especially is someone else is picking up the tab...

if there's that much clearance it's been severely mistreated, sounds like the alloy spindle has been eroded by the misaligned/damaged steel bearing, little you can do but replace

but you do not need those tools, i've got bb30 and have done regular servicing including removing/refitting the bearings for cleaning/regreasing, you can do the job perfectly well with much simpler tools

given the lack of local availability/support, you may be better off fitting a bb30-threaded adaptor

I have already asked a local mechanic and given him rough dimensions of the tools which I found on internet. Will probably get them made.

I am just a prospect cyclist and can't afford to damage $35 bearings that is why I was reluctant. Unlike where you live $35 is 3500 rupees here, a monthly wage of a waiter.
But I can see how you see this and I don't blame you.

Okay thanks. I am going to try to replace the bearing with the available stuff. Hopefully I dont damage the bearings.

About the spindle I am thinking of coating it with some adhesive where the bearing meets the spindle.

Do you know any other way of removing the clearence?
Cant afford a new crank. Even if I had the money there is no shop here.

Same with threaded adapters. Not available here.

Thanks for the suggestion anyways.

Please don't apply an adhesive or locking compound to the spindle at the bearings. Some green level Loctite bearing retainer for the bearing at its contact with the shell is sometimes necessary with a BB30.

Read the .pdf for the BB30 set up, scroll down a few sections and read the Cannondale instructions on BB30 installation if you have any noise coming from the bottom bracket. Best of luck.

I have a Cannondale with BB30. I serviced bearings fine with rubber mallet, piece of wood and 10mm allen key. No expensive park tools in sight. Google what you need to do, it's easy.
