Cassette, chain and front ring wear questions?

    Hi!

    I hope you are well,

    I am commuting to work every weekday on my roadbike. It has an 11/32 rear cassette, 11 speed Sram chain and 50/34 chainrings up front.

    I check the chain wear every month or so and when it is past .5 worn, I change for a new chain..

    I just changed the chain recently and on the 7th and 8th gear on the rear, it tends to skip under power..

    As I have put a couple of weeks commuting kms into it... it has seemed to have skipped less..

    I washthe bike about once a week...

    My question is: is there anything else I can do to extend the life of the cassette, chainring?

    I think the 7th and 8th cog is where I do most of my riding so has worn more quickly...

    I imagine I would have to change the cassette after this chain is worn... so can ride it until it is significantly worn?

    Thanks for reading,

    A

    generally people will change the cassette every 3 chains (though some do it every two chains). how many times have you replaced the chain?

    Take a picture and put it up of your cassette and chainrings. It is most likely wear. You could up your rpm and use other cogs. Other than waxing, not a huge amount else you can do to increase lifespan. If the chainring and cassette is worn, it will wear your chain quicker as well.

    This practise has served me for years but on Shimano chains I change at 0.75 which means I get a little longer than the OP.

    thanks for the replies...so if this is the last chain woth this cassette...

    can I ride it until it is even past .75 wear and then replace both?

    Ride it until it starts slipping if you are getting rid of everything after. Personally I would try and use different gears and spin a bit faster, you will get way longer.

    yep, my chain wear checker is set for .75% and 1% wear, so i usually wait until it just nudges into .75%.

    The reason it is skipping less now is that the new chain has worn into the old cogs.

    I change chain at 1.0 (approx 5,000kms) and change cassette every 2 chains. I do the large chainring after about 5 chain replacements. (I don't ever recall changing a 34 chainring).

    i think that 7th cog on the rear and 34 ring up front are obviously my ideal gear for cruising along to work!

    Just curious but a 32 on the rear sounds excessive for a commute. Is your commute very lumpy or very long? If not, you may be better served with a low maintenance single speed.

    Hi! fair point ... i do cycle uphill towards Sandyford from town.. so a bit of climbing & I cycle a fair bit outside from my commute and love to climb..but apart from that, a fixie would be good!

    Well prehaps a single speed rather than a fixie. Fixies take a bit of getting used to especially on wet roundabouts as you can't coast.
