get tough or get tripple?(4 posts)

get tough or get tripple?pusher

I live in East Tennessee. I ride cross country(with an mtb) and on the streets with a road bike. My lowest gearing is 39 to 26. Isn't there such a thing as proper cadence? I can't imagine riding over the Smoky Mountains with my gears so steep. I must be riding too slow, I guess. I know I should be getting off my seat ocasionaly so that the blood can flow to my prostrate. But, I have to stand for every hill here in East TN. I don't have the money for the tripple conversion right now. So, tell how I can stay true to my double.

If you have a Shimano drivetrain, you will likely be able to get a cassette some pretty large gears. Post what your drivetrain is, and someone here may know just how large a cassette will be compatible...

All Shimano: 105 crank 53,39; 8 speed cassette 12-26; 105 rear derailer with the short cage; RX 100 front derailer; RX 100 integrated controls with a middle "ghost" position for the front derailer. The guy who built my bike up told me that I could use a triple and get by with that shifter. Is he right? I presume that to run a triple I would need a new rear derailer (longer cage) but not a new chain (max gearing would actualy be reduced by one tooth since triples use 52 tooth big rings)
I have an 11-30 8 speed cassette on my mountain bike. I might be able to just swap it out. I think there are at least 4 extra links in my chain.

There is such a thing as proper cadence and each rider has his or her own. The most commonly recommended, of which I'm aware, is 90rpm or better on the flats and from there down to about 70rpm in hills.

Now, in truth, this varies quite a bit and there are bio-mechanical reasons for cadence variance under different conditions. I try to keep it over 100rpm on the flats and between 85-70 on hills. However long hills or mountains may force that cadence even lower. For instance, I did a mountain ride last weekend with a 10-mile climb where my cadence was usually around 60rpm and it was quite comfortable.

As I said, every rider is a little different. On flat or hilly roads I ride a 53-42 chainring and 12-21 cassette. In the mountains that changes to 53-39 and 13-26.

The answer to your question about tough or triple is "probably both." I used to ride a triple until someone years ago pointed out that I was never building my climbing strength. In fact, without the triple I am a better climber now than I have ever been. It just took time.
