Ok, So I climb hills. But I also like speed.
I currently run standard front chainrings, but they are being replaced this week.
So do I stick with the old or go with the new ?
Im running an 11-28 but I'm thinking that I can get a tighter cluster using compacts.
Then there is this Dirty Dozen ride coming up.Is it Madness to try that on standards? Maybe....
Will my top end speed really suffer with the change ?
Who has tried both ? What do you prefer & why ?
On my 1980's steel frame I had 52/42 and 12/23 (guess) 6 speed but I was not a serious rider. However I could ride up the corkscrew. In 2000 I bought a new bike and it came with a compact. I did not know anything about what or why it did, I just rode it around. Eventually when I got cancer I decided I had better ride the TDU challenge just in case and broke my spokes, the last one wrapped around the chain and threw me off just after the finish.. Anyway after 10 years I got a new bike and once again the LBS supplied a compact, still no explanation! I now have 11/28 at the back as I could not get up Checkers. I now know what you are talking about but note my riding partner (61 years) has an absolutely standard setup and he can ride up everything steep in Adelaide. He uses the Corkscrew as a time trial while I am staggering behind. Its frustrating having all this gear (like Contador at the Giro) and still its a struggle. So its the rider not the bike, depends if you like sitting or standing up hills. My SRAM does crunch a lot when changing due to the large spacing. In the end I have dreams of riding the famous Tour mountains and think I should stick with the compact.
Even the most doped up riders on earth use compacts with a 28 on the back sometimes. Even a 32 for the Angliru.
Anyone NOT running a compact around the hills in Radelaide is losing watts as they struggle to 'stay on top' of the gear IMHO. I can't think of a single rider that COULDNT ride up Woodlands Way (Norton Summit secret training route) faster by using a compact vs standard.
Ive riden both with a power meter and objectively Im faster with a compact up the steeper climbs. I can ride CS in 53x19 and stay in the saddle all the way up. I've riden a 9:01 with 34x25 though.
If your grinding, your losing watts. You want cadence of 80+ MINIMUM up any climb. Even if your on NASA drugs. ;)
It depends though, if one is a flat lander and only does something like Norton Summit once a year then a standard crank will be fine but if you like to challenge yourself in the hills against your mates or the clock then compact HANDS DOWN!
Racing in Australia you won't need a compact though as rarely are any steep climbs involved. Reality is going out with your mates around the hills you will be doing more elevation than any NRS race on the 2012 calendar 99% of the time.
Failed Woodlands Way with compact 12/26, must try with 11/28! My NS PB did get better though.
Anyone had a close look at Sagan's bike...its hard to count the teeth on his chainrings but they look closer to being compact than standard.
Sagan's specs as reported on Cyclingnews, not sure if changed when on different route though.
Cassette: SRAM XG-1090
Chain: SRAM PC-1091
Crankset: Cannondale Hollowgram Si SL, 53/39T
Watch SAGAN at 26 sec wonder if he'll do this on his next stage win
Robby McEwen did this occasionally as he crossed the line !
That is a great price for the FSA crank set (even if it is showing 279.99 for me).
It is a very good crank set - it is what I use, and I was happy getting it for around $500.00!
