Record triple with 13/29

mallyg · Apr 23, 2004

Last week I had a 13/29 put on my bike to give me extra gearing with my 53/39 double (I'm doing l'etape this year). However, hearing just how many etapists were opting for a triple, I went into panic mode and changed my double too. So, I now have a triple, but still with the 13/29 cassette. Any views on this?

Cool if you are climbimg walls or dragging around an extra 100 pounds. A 39x29 is the same gear inches as a triple with a 30 in front and 23 in the rear, so a 30x29 could be overkill.

I'd think about the 13-26 with that. You'll still be lower, and you'll have a nice tight cluster of cogs.

The 29T would be awfully low.

Yes.still have my 11/23. I'm running a 53 at the front.

Actually, I went for a ride this morning and the gears felt good. I agree, I'd probably never use the 30/29, but could possibly use the middle ring with it occasionally if I didn't want to drop down to the granny ring. I'm not sure I see the benefit of changing to a 13/26, because for most of the cassette it's quite tightly spaced (I think, between the 13 and 23, it's the same spacing as the 11/23). If anything I'd get a 12/26, giving me an extra gear at the top (bottom?) end. However, bear in mind that this setup is really for the Etape, which is 150 miles including climbs that you reach after about 90 miles. I figure over that kind of distance I'm going to want to preserve my legs by not pushing too heavy gears. After that event, I'm going to change back to a double. I actually didn't have much problem with my 11/23 on hills, I think it's more of a psychological thing to know that I've got low gears in reserve should I need them.

good luck! you should be set then, youll definately have low enough gears, and you make a good point about your cluster still being pretty tite with 10sds and the big jumps prolly just between the few largest cogs right? im just thinking id rather walk tho then use that 30-29 tho, prolly save ten times the energy.

Good point the low gears helping to conserve energy on the long rides. With a 30/29, you'll certainly have a low gear if you need to fall back on it. And agree on the 11 cog, no use for that one either unless you're a racer.

I've got a triple also, running a DA 12-25 cassette with 30/39/53. Don't use the inner ring at all on most shorter club rides when the pace is high over rollers, but the triple really does help to conserve energy on a mountainous century ride.

Would like to learn more about the Etape. Is this an event for amateurs which runs a stage of the TdF?

Personally, I would start with a 12 on the cassette. You have the climbs covered, but you if you have a tailwind, you can use 53/12 very effectively on flats and slight grades, not to speak of descents. Until you get to where you want to brake instead of accelerate or maintain, the 12 will be useful. 1 tooth on the cog is 4 on the ring. My choice would be a 12/25 cassette unless you've got 30+ degree grades at the end, where a 30/29 pairing could compensate for fatigue. If you have a granny, why not rely on it.
