why are the cyclocross chainsets? http://www.planet-x-bikes.co.uk/i/q/CSFSGCC/fsa_gossamer_cyclo_cross_chainset_megaexo
Eh? Why are they what 😕
Because it's a 46/36 which are chain ring sizes pretty peculiar only to CX. Road compact is 50/34.
Because they come with 'cross friendly gearing rather than road gearing.
36/46 chainrings? Classic cross combo.
a bit friendlier on the old legs then
There's nothing leg friendly about cyclocross 🙂
There great, especially when going from big to small.
Leg friendly until you spin out on a 46 / 11 combo at 30mph... If you love super high cadence then go for your life.
while this reminds me can i change the bottom ring to something a little smaller on my (same) chainset without screwing the gear changes
doubt I'll be reaching 30mph to spin 😆
IMO for real cross gearing the inner ring is too small and the big ring too big! I run 39/44 with a 12-27 cassette, having said that it very rarely touches the 39 anyway.
Agree with Blazin completely here, if you need a 36 then its quicker to run
who makes the 39/44 cranks?
No-one, you take a standard 130mm bcd road chainset and put your own rings on.
38/44 with 12/27 cassettes here as well.
