Thanks for the advice in this post. I am also a 'challenged' hill climber, weighing in at 105 kg and 6 feet. I have been trying a lot of gruelling hill climbs living in Sydney of late (away from the flats in Melbourne where I usually live and ride) to improve, and am making progress.
My question is this - I have (stupidly!) signed up for a 1 week bike riding tour to next year's TDF, in the Pyrennes. I currently have a 11-23 speed cassette on my bike and a 52/39 front. Currently I can comfortably turnover 39/23 on the steepest hills but not at great speed.
Is changing the gearing (say by adding a 13/27 cassette) or adding a triple to the front going to make me any faster, or just give me more options to make my present (slow) speed. Eg is higher revs at 39/27 going to get me extra speed?
Hopefully by July 06 I'll have better climbing fitness and will have dropped some weight to improve things as well.
Cheers

mmamster,
I did a 3 week bike tour through France this year, with a week in the alps and mt ventoux on the way. There are several factors to consider. How many kms a day you will do overall. How much climbing. How long are the climbs. How fit you are. How much time you will have to finish the day's riding. What gears you have. Is there a sag wagon. Whether most of these are an issue for you, only you can judge.
For me, I made sure I was pretty fit (I was on the trip at 85kgs, down from about 90kgs), I swapped my 12-25 for a 12-27, and I took it easy when I could. We had a sag wagon, but I didnt need it. We had to ride 80-90kms a day overall. In the alps, we had to do 60-70kms a day with about 25 kms of climbing (we had the option of doing as much as we liked, but this was the minimum to get to the next stop). We had all day to do it, so there was no rush. The only time I pushed myself a little bit was going uphill. the rest of the time, I just rode comfortably. I mean, you gotta take in the scenary, the culture, and frequently stop for french food. I think this lack of effort on the flats really helped me when I had to put an effort in to climb.
I had no problems with the trip, but I had to get out of the saddle a lot for the parts that were above about 11-12%. I love my 27, and used it on all the big climbs. And I climbed a lot of hills, many of them back to back. I would have loved a triple or a compact crank to give my legs a break on some of those monster 20+km climbs (ventoux, madelaine, telegraphe-gailibier), but all I needed was a simple cassette change to get my 27, and this was the most cost effective option for me.
Other riders had triples, and you could clearly see the higher cadence they used. I went past quite a few of them, and a couple flew past me. I think the big issue with a lower granny is not the speed with which you climb the current hill, since people can climb fast with either a low cadence or a high cadence, and we can all make it up a climb if we have to. The benefit is found on the hills you have to ride next (and in the pyrennees they are all close together), since a lower granny can save your legs a little and you spin your way to the top.
A couple of people actually swapped from 25's to 27 or 28 during the tour, and noticed a big difference in being able to climb the next hill, and didnt need to stop as much on the current hill. For them speed was not the issue, just getting to the top of each hill.
With my 27, I was definetely not spinning, and I was hurting on every big hill. But I had enough left in the legs to get up the next big one. I was down to 7 km's an hour on some of those beasts, so I hate to think what my cadence was. I would have made it with a 12-25, and I suspect my speed would have been pretty similar but I don't think I would have enjoyed the trip as much. Too much pain!!
Mate, nothing stupid about riding your bike through france/spain, especailly during TdF. Just get fit, get a granny that suits you, and get over there and enjoy. I loved every second of my trip.
Hope that helps.
PS
The company I used was Wide Open Road. We rode from Bordeaux to Alp 'd'Huex (past mt ventoux), then spent a week in the alps to watch the Tour de France.
