Front chain ring
My 62 year old legs are loosing some power and I ride hills a lot, big
hills. I have two chain rings up front, a 50 & a 36. I have a 10 sproket cluster in back going from 12 to 25. I want more climbing geers and wonder how to do it. Should I simply go to a 42 36 chain ring up front or a different sproket in back? |

What you suggest will only get you another click. |

That'll give you a low gear 27% lower than you have now whereas the suggested triple would only be 17% lower. And the cassette can be switched back and forth pretty quickly for rides in flatter terrain. Either way would require a new rear derailleur and the bigger cog will probably also require a longer chain. |

What you suggest will only get you another click. Keep in mind that that chainring combo will require a FD designed to handle a 14t gap. I know from experience that Campy Triples won't work, nor will Shimanos designed for a 52-42-30. The chain on the middle ring will be too low for the ramp to derail it onto the granny. Ultegra 6603 and Dura-Ace 7803 are the only ones I know of that are even close, with their 52-39-30 combos. Also, until very recently, most STIs were double/triple specific, so there's a reasonable possibility that the OP couldn't go to a triple without _considerable_ expense. I like the 11-34 cassette idea. I paired one with a 50-34 crank on my CX bike, and I have a 1:1 low gear, which can't be said for most Road Triple setups. |
