I'm quite new to bikes. Thanks to youtube I fixed some of the shifting issues I had in the front derailer and now I can shift to all the gear combinations. But I found a something strange when I'm back pedalling.

My bike's got a Shimano alivio 3*8 gearset. When I'm on the 3rd gear (largest chainring) or 2nd on front and my rear is on 1st (largest) cog or 2nd, if I back padal for a while chain automatically slips to the next smallest cog on the rear thus causing jam.

I have looked at some posts here includng this one, http://bicycles.stackexchange.com/questions/280/how-to-fix-new-chain-that-switches-gears-when-pedaling-backwardsHow to fix new chain that switches gears when pedaling backwards, which says this could happen due to worn out cogs or dirty cogs. But my cassetts and chain is new and clean.

I guess this is more of a gear tunning/adjusting thing but can't seem to fix it. Any help is appreciated!

automatic gear shifting (slack chain) when reverse pedalling
