Going from double to triple crankset...(8 posts)

Going from double to triple crankset...Canada Marc in Montréal
Oct 17, 2001 9:02 AM
Hello all! In less than 2,000 km it will be time to change the crankset on my road bike. I am currently thinking about going from my actual double Dura-Ace to a triple. Anyone on the board have already made the change? Do you know U.S reviews about this fairly new product? The european ones are not very informative... :o( Thanks! Marc
Sorry abouth the double postings...Marc

I just received a Performancebike email. They are selling the upgrade kit for $719.99us. As you can see, it's alot more than upgrading the cranks and BB. According to Performance Bike:

Regular Price:$719.99
Item #50-1437E


Everything you need to upgrade your current Dura-Ace 9 Speed System to a Triple! Braze-On Front Derailleur, for Clamp-On use item number 50-1488. Includes Dura-Ace Triple Crankset, Dura-Ace Triple STI Levers, Dura-Ace Triple Front and Rear Derailleurs, and Dura-Ace Triple Bottom Bracket. Choose 172.5mm (725) or 175mm (75) Crank Arms.
Thanks for all the info!!!MARC

Why does your crank need to be replaced in 2,000 km? What's actually wrong with it? I'm truely curious. Are you worried about fatigue life? Chainrings can be replaced and helicoils can be inserted in the pedal bores. the only thing that is hard to fix is the BB connection. The square tapers get worn with lots of removal/installation, but a splined setup should be fine indefinitely.

Since your DA unit is "shot" would you mind giving it to me? ;-)

Hi! The double crankset has seen 33,243 km so far... and is in bad need of eternal rest as my LBS mechanic told me! Bye MARC

Didn't know going from a D/A double to a D/A triple was considered an upgrade. I've heard that the D/A triple has a 39T middle ring instead of the 42T middle that all of the other current Shimano road triples have. I see that as a good idea.

But I'd love to be just off St Catherine in Hurley?s with a pint of Guinness and reservations for dinner at Le Muscadin.

Montreal is one of my favorite towns.
