Hi Guys,
I am looking for a Road Chainset and Crank to replace an old ugly thing, looking at cost, happy to spend nothing, but I can sort that out, I just need someone to advise or help me with the difference of Teeth count if you can.
What do I have at the moment....
Crank - Shimano M341 48/38/28 - 8 Speed
Cassette - SRAM PG830 11-30 - 8 Speed
I want to stay with a triple and 8 speed for now.
This is on My Trek 7.3FX HYBRID, but its Road parts i am looking at. Would you suggest sticking to same teeth count of or would there be any benefits to changing.
Please stick to topic, I know buying a new Road bike would be better, but not happening.
Appreciate advise.

Maybe I should have asked if anyone knows if this is Road Parts, or MTB sorry.
Crank - Shimano M341 48/38/28 - 8 Speed
Cassette - SRAM PG830 11-30 - 8 Speed

It's more MTB/hybrid stuff but it all works the same way just different ratio's. If your staying with 8spd and want to keep such wide ratio's I would recommend MTB/Hybrid specific parts.
As for number of teeth that is a personal thing that only you can decide. If you use all the gears and feel you need them all then stay the same. If you find you only use the highest gears and spin out then get larger chainrings. If you find the ratio's arn't close enough then change the cassette for closer ratio's and then you may need to adjust the chainring size in order to retain similar upper and lower limits.
Your best bet is to describe what you wish to achieve/what you currently find wrong with the gearing on the bike other than just aesthetics. If you find the current gearing works well for you then stay with the same ratio's but get newer stuff.0 -
Cheers for comments, sorry I have not been around. Back went so have been healing the past 2weeks. In this time I have serviced my crank set, so no need to worry about changing at the moment, going to save the pennies for something better next year. Spend this year getting fit and losing weight, cost effectively
