Depends on what he screwed up, if it just a small thing try this, there are two screws that need to be adjusted for the chain lead!!

See the pictures below....

Ok, so your front sprocket gripshift has been tightened too much, eh?
Just loosen the nut [#5 in the image below] below the gripshift that adjusts the tension of the cable!!!

I agree, the last cycle has a crazy chaindrive setup, with internal transmission!!!!
Well it costs 5000 $, thats 2.35lac Rupees!!!!

Plus, cycling is all about getting back up and pedalling away!!! I've fallen over the bars many times over!!!

I kno what u mean eddie.

But my handlebar to front wheel's link broke while i was trying to max the bike. Damm scary with the handle straight, and the front wheel with a will of its own ;-)
Dont trust bikes that much anymore.

Prabuddhadg,
Lol.... i thought you meant like the 3 spoke mag alloys sometimes seen on bikes :P

Cowiee,
If you can be a little more specific i can try to help....

Edmund,

That moonlight trail thing sounds amazing!
Those are some pretty sweet bikes u posted...
Its insane the amount of technology that is used in these bikes!

My friend had a GT frame as well but cracked it right near the rear disc mount when jumping on his rear wheel.

Following in your footsteps i thought i would post some more pics....cept this time the bike is mine Its a `05 Specialized Hardrock sport.

When i bought it -


Then i really wasnt impressed with the fork that it came with stock, so i bought a 80-120mm Manitou Black w/ RTWD (Rapid Travel Wind Down). Which made the world of a difference to my bike.
Next i need a new crankset and bottom bracket, and am planning to take of my front deraileur to shed some weight as i never use it.

And then i want to paint my bike like this > (note the new fork PS'd on )


Heres another random pic -


Will post more pics of more interesting bikes later.

@rehaan: the front shift is really screwed.. the cable has been tightened too much... sort of loosened it but still not as original... now at some gear combinations the chai touches the shift mechanism...
@ edmund: loosening the nut did not help much
please help

I'm even more confused now!

Firstly, if the cable has been "tightened too much", the only thing that will happen will be that the bike wont shift to the higher gears (smaller cogs).

Unless you mean that the cable does not travel smoothly in its housing? ie there is a lot of friction for some reason?

The chain touches the shift mechanism? >> If you mean that the chain is not perfectly aligned with the cog that it is supposed to be on, and hence makes a sort of clicking noise (more than usual) this can be fixed by turning the fine tuning barrel adjuster the slightest bit to realign the deraileur.

Let me know exactly what you mean once again and we can take it from there!
