|Campy Triple: Middle Ring Compatibility with Granny||Fred the Cross Poser|
Jul 11, 2002 7:18 AM
|Hey Folks -
I have replacing my Veloce 32-42-52 triple crankset with a new Racing T crank set. However, the Racing T has 30 tooth granny. I would like to replace the 30 tooth with the 32 tooth from the old crankset (easy to do) but I am wondering how that would affect my shifting. The Racing T middle ring is marked 42/30.
The granny from the Veloce crank is the same type EXADRIVE ring and is great shape (I don't use the granny much...)
Thanks for your help in advance!

|My bet is that a larger small ring would only improve the shifting. Typically, the closer the sizes are, the better.
Why do this, though?

|Currently, I don't really need the smaller granny for the road. I look at the granny as a kind of safety net for those steep grades at the end of a century (Cape Cod, Truro comes to mind). Otherwise I would be fine with a double.
I am also looking at possibly using a closer range cassette and using the granny more for those New Hampshire hills. The 32 is better suited to my riding style.
I am installing the old Veloce crank on my cross bike (currently a 52/42 Shimano 600 double). I was thinking the 30 ring is more appropriate for some short, but steep, grades on a local trail nearby (the 42 causes the tires to spin in the gravel).

|You might consider a smaller cog, more closely spaced cassette, instead. You might actually get closer ratios that way, plus it does so in all three rings.
More $$, though, but extra cassettes come in handy.

|If the small ring is a luxury, my 1st priority would be to get exactly the gear ratios I want on the middle ring. The difference between a 30 and a 32 won't matter much and riding on the Cape, with no mountains and lots of wind, really rewards using the straightest block you can.|

|In Truro, on the west side near the Wellfleet town line is a long killer grade up what used to be a sand dune. I am used to New Hampshire hills and I still would define this a killer grade. Who would think that you would find a grade like this near the end of the flat Cape....|| |
