ASTANA Posted June 8, 2009 Share After using a compact crank set for a while now, I am looking at changing to normal/ bigger chain rings. Uses 50/36 front, back 12-25, but this only gave me a advantage in climbs. With all the flattish / rolling hill races in WC I need something that gives more speed. What is considered a good option 52/39 or 52/39 ? any thing else ? Link to comment Share on other sites More sharing options...
NotSoBigBen Posted June 8, 2009 Share 53/39 I reckon is what 80% or more cyclists use these days (At least those without MTB type triples on their roadbikes ....), I guess that coupled with a 12-25 at the back? Link to comment Share on other sites More sharing options...
wannabesub3 Posted June 8, 2009 Share I use 52/39 with 12-25 or 12-27 for the really Hilly climbs, and 52/39 with 11-23 for the undulating rides Link to comment Share on other sites More sharing options...
Bellscycling Posted June 8, 2009 Share Just get a 11-23 cassette, as a 50-11 gear ratio is actualy a bit bigger than a 53 - 12. You will still have the advantage on climbs and you won't run out of speed on the flats. Link to comment Share on other sites More sharing options...
Andyr249 Posted June 8, 2009 Share I have a 53/39 with an 11-26. Works great for me. Link to comment Share on other sites More sharing options...

ASTANA Posted June 8, 2009 Share 53/39 not very big ? Most new top end bikes come with these standard these days, so was just wondering. Most races are undulating, and once in a while there is a climb (longer than 3km). I really like training on hills though, so what would be the best setup at the back ? Do you change cassettes for races with hills etc or do you have another set of wheels for these ? Link to comment Share on other sites More sharing options...
