Compact to Standard Crank; or I feel really stupid
 
So every once and a while I have one of those brain fart moments. I replaced the compact crank on my TCR with a standard crank, and when I went to adjust the (braze-on) derailer, I couldn't move it up high enough to clear the chainring. I pondered it for a while and thought about posting here, but finally remembered that there are two holes in the FD to screw into the braze-on slot. Moved down to the lower screw to raise the FD up and problem solved, but I sure felt stupid for taking so long to remember about the other hole. doh.

Its what came on my TCR. I've been racing my Tarmac with a 53/39.

I prefer a compact crankset. Only reason I dont run one all the time is my srm.

(Pssst... don't tell anyone, but I run a 46/36)

50x11 @ 100 RPM = 35.5mph
53x11 @ 100 RPM = 37.7mph

but (in gain ratios):

39x23 = 3.3:1
34x23 = 2.9:1

To me, 6% loss in speed on a downhill is worth a 13% reduction in pain and agony on an uphill... YMMV.

Brian Ratliff 04-18-08 01:34 PM

In racing, it there is no reduction in pain or agony on an uphill. With lower gearing, you just go slower.

Even in my on "hilly" race (Tour of Willamette, for the Oregonians), I never (or barely) touched the 39/25 I brought. The pace was too high. I surely did top out the 53/12 on my cassette. I left the race wishing I had run an 11-23 insteady of my 12-25 for the last stage. Wouldn't have helped much though ;).

You need to race steeper hills.

Back in the old days, we were real men and ran 53/42, with a 12-21 in back.

Can't. I'm a sprinter.

Most of the road races around here, the maximum grade is around 8 or 10%. In the Willamette race, it was 2 miles of 8% on the last stage and the lead group was really flying. I lost contact almost immediately. Smaller gears would not have helped my cause.

My knees remember those days. One glucosamine tablet at a time.

I must be older than you: 14-19 in the back with that fancy new 6-cog freewheel. 14-18 before that.

Of course 42 was the smallest inner ring with a 144 mm bcd Campy (or Campy copy, like Sugino) crank. 130 mm bcd cranks were from that weird fishing equipment company from Japan.:)

I remember having my first race bike built. I was chastised for having a 25t rear. Real racing men had a corn cob freewheel. Nailed their cleats to the leather sole,too.

My trek had a 52/42 superbe crankset.

It's now with a BF member in Texas and has been replaced by a centaur compact crankset. I like being able to stay in the big ring for crits, even those with a hill thrown in.
