Woshko Posted July 11, 2018 Share Posted July 11, 2018 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. Quote Link to comment Share on other sites More sharing options...
Wojtek Z. Posted July 27, 2018 Share Posted July 27, 2018 (edited) 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. Edited July 27, 2018 by Wojtek Z. Quote Link to comment Share on other sites More sharing options...
Woshko Posted July 27, 2018 Author Share Posted July 27, 2018 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 I feel a huge difference between 12-32 and 11-28. Didnt expect that... 1 Quote Link to comment Share on other sites More sharing options...
