Installing Triple Crankset/9 Speed Cassette on Sofrider

May need to upgrade front derailleur. Otherwise, sounds like an upgrade right up my sleeve. Triples are way under appreciated, in my opinion.

Hi Rome,

Your current front derailleur will work fine. The SRAM left shifter should shift it okay. You may need to adjust the derailleur height in the mount depending on your top ring tooth count.

What chainrings do you expect to use, and what crank length are you considering?

Lemme know what you have in mind; I have converted a Sofrider V2 to a triple with disc brakes. I used the original 48 tooth top ring and used a "triplizer" to attach the granny ring. Other options are now available out there...

Best,

Doug

Hi Rome,
I'd ride it a bit as it is till you settle in, then you'll know where to make your gearing decisions.

Hi All,
I am planning on a crank length of 155mm and I was thinking about a 46-34-24 combination. Up here in Maine, I ride on a lot of fire roads, rails-to-trails, and some country roads. It's hilly in a lot of areas. Thanks for the help

On my conversion I decided that the existing MTB crankset (46 teeth on largest gear) just didn't give me the top end I needed.
I installed an Ultegra 30, 42, 52 triple with 172.5 mm cranks. I am running a Deore front derailleur and I have crisp clean shifts with just a touch of chain rub on the outer limits. There is no rub with a little thoughtful shifting! I am using an eight speed rear cassette.

I have more downhill power than any recumbent rider could ask for! Cleaning up on the roads, with the ability to navigate stairs! Who'd have thunk!

Can you post more details?  Pictures?  Thanks! charles
