Claris R2030 gear ratios


Recommended Posts

Hello there

I ride a 3x8 Claris groupset, that means 50-39-30 in the front but a Tourney CS HG200-8 Speed casette in the back which means 12-14-16-18-21-24-28-32.

I seek your opinions as SickBiker suggested a 12 -25 casette for this setup.

It all depends on terrain around you. If you have flat roads in your neighborhood with max gradient around 10% you can use 12-25 cassette and it will be all you you need. Then it will be also easier to choose the optimal cadence on flat road.

In 30km radius its FLAT around here. After that its hills and even 15% gradient. However I already switched to 11-28 becouse I was so inpatient :D I feel a huge difference between 12-32 and 11-28. Didnt expect that...
