I am looking for opinions on the strongest 8 speed cassettes and chains. I am aware that these are normal wear items, but it is getting tiresome to have to replace chains every 10-15 rides due to chain stretch and cassettes every 6-8 weeks due to sheered pins, and bet cogs.

Not sure if these failures are related to my size, 6'3" 300# and far more of a masher than a spinner, or quality of part or both. I am not attempting shifts under load .

Yes I realize the world has moved on to 9 speed, and if I need to move on in order to get longer service lives out of components so be it, but I am hoping to get away with a minimal number of new components.

Go 9 speed there is a much bigger section. Also you will get much better components if you go 9 speed.
Here is what i have and i have never had any problems with them (yet) but i do not think i will. I am 6,0 and 250 lbs









Or just stay with the 8 speed i will cost quit a bit to convert you will need a new rear derailleur, shifter, cassette and chain.

No need for a new derailer, just need the shifter, chain, and cassette.

i thought you needed a derailleur to maybe I'm wrong but that what i had always bin told now you got me wondering.

Nope on the rear derailleur, the old one will work fine.

Learn to spin...your stuff will last much longer...seriously!!!!

If you 300# and you mash, your going to wear sh!t out quick...its reality. You'd be better off running a singlespeed. Gears exist so you don't have to mash.

That said, there are few and far between on quality 8 speed parts. Shimano HG91 or SRAM PC890 chains are the best 8 speed chains available. Shimano HG70 or SRAM PG850 are it for cassettes unless you want to e-bay it for XT cassettes.
