Triple with 53/42/30 or 53/39/30 ?(14 posts)

Triple with 53/42/30 or 53/39/30 ?Matteo
Sep 25, 2002 8:39 AM
Pedaling in a hilly area and having this cassette:

13-14-15-16-17-18-19-21-23

do you think it's better a triple with 53/42/30 or with 53/39/30?

And why?

Thank you very much.

Matteo

The 39 more closely approximates the gears on the 53 and 30; therefore I'd go with the 52.

Actually, Id scrap the middle ring altogether; the 53X30 makes for a nice layout with the cassette you have on.
oops, 52 shouldvebeen 42. nmSteve_0

Id find a 30 which sizes to my crank.

I guess if one doesnt exist, I wouldnt....Whaddaiknow, I run a single 46.

I'm running the 53/42/30, which I prefer because a double shift of one cog in the back + one ring in front (42-53) gets you to the next gear in ratio order, i.e. you can double shift reasonably. With the 53/39 there is more duplication and it takes two rear cogs plus the front shift to get over to the next nearest ratio.

I use a 52-42-30 with the cassette you have. I use the middle ring and stay between the 14 and 17 cogs on the back for all but the really big hills. If you spin faster than I do or need easier gears for routine riding get the 39.

At least for me, and I think most cyclists of average ability (nothing personal...), a 53-tooth ring is wasted weight. I almost never used it with a cog bigger than 23 or so. A 46-36-26 lets me spend more time on the big ring and gives me more usable gears. I don't use the granny very often in normal riding, but when I need it, a 24 or 26 is much better than that lame-@ss macho 30-tooth.
Agree. I'm currently running 48 - 38 - 24. NMfrankamo

Where do you get road cranks with 48 - 38 - 24?bigskulls

Almost every triple I see is 53 - 39- 30. Do you have to buy new cranks and then a whole set of new rings?

MTB cranks look like that. Are you running one of those instead? Is that possible/desireable?

You may not be able to buy one that way,but you can put them on Shimano road triple crank with 130/74BCD.A 5 arm XTR has the option of 48/36/26

Go with a 42 middle if you insist on a triple. The 30 and 39 make little difference in gear selection.

I have a 53/39/30 DA triple now, and used to have an Ultegra 52/42/30. I love the 39 in the middle. I'm almost NEVER in granny. I mean never. Unless it is one of those 15% climbs that you hit a few times a season.

With the 42, I had to use the granny a lot more. Also, the 39 is the same as the small cog on most doubles, so it gives you a better sense of how you are riding in comparison to your double-equipped buddies.
