Favorite Cranksets

I have a 2005 Lemond Poprad and am planning on touring with a trailer this summer across the country. I'm already set on the bike I am using and the trailer. I do however need to switch out the front crank for a triple, as it only has a double 46-38 on it currently. The bike currently has full 105 drive train and I was thinking I would probably go with a a new triple 105 derailleur. For the crank however, I'm Looking for something like 22-32-44. I'm curious which brands and models of cranksets people really like and recommend. I was looking at the '08 Tiagra but I'm open for some other suggestions. I was told by my LBS that if I was to put the Tiagra on, i would need a new bottom bracket also. Not exactly sure why but I'll go with it. Anyways, give me some tips. Thanks
Craig

There are several different standards for the way a crank arm fits onto the bottom bracket cartridge. I think your bike has an ISIS splined bottom bracket. If you are going to replace the double crank with a triple you'll have to get a BB cartridge that has a slightly longer axle so that you get good engagement with the crank and the correct chainline. So you could go with the longer ISIS cartridge and a MTB crank with an ISIS interface made by companies like Truvativ and FSA. Or you could go with a Shimano MTB triple and a Hollotech BB. Or you could go old school and get a square taper BB and something like a TA Carmina 94x58 BCD triple.

PS The Tiagra won't fit 44-32-22 rings.

Sugino makes some popular road touring cranksets, but they don't come standard with as low as teeth as the standard MTB crankset you are looking for, but they do come with a lower chainring setup off the shelf than Tiagra or 105 does. They have 110/74 bolt center diameter and come off the shelf with 26-36-46 chainrings. One of these Sugino cranksets combined with a MTB derailleur and MTB cassette on the rear makes for a nice touring setup on a road bike. You could also potentially keep a road 12-27 cassette if that is what you already have, and replace the front 26 chainring with a 24 chainring to get a lower low gear, although some folks on here might argue that that is still not a low enough gear. There is also a gear calculator at Sheldon Brown.

You'll have to go with square taper if you want to user a Sugino XD

You may need to consider an mtb rear derailleur if you are going to a wide range of gearing.

If the cassette is a 12-26, with a 22-32-44 the range would be 23" to 99". Myself I'd get a TA Carmina with a 94x58 BCD and 46-34-20 rings, this would give you 21" to 104" with nice close ratios

If he has the long cage 105 rear derailleur, the capacity is 36 teeth so the first combination would be (26-12)+(44-22)=36 so this would work.

For the second combination, it's (26-12)+(46-20)=40 which would exceed the maximum capacity of the current available 105 rd. Using the LX rd, which has a capacity of 45 teeth would work and would be compatible with any shifters that suited the 105 and the cassette.

Those look like a nice set of gears for touring.

Here is another relatively inexpensive, but reasonable quality crankset---the Octalink V2, Shimano Deore MTB crankset with 22-32-44 chainrings for $75.00.

https://www.universalcycles.com/shopp...21&category=64

It requires an Octalink V2 bottom bracket, also available at Universal Cycles, from $15 to $40.

Universal Cycles has a wide range of MTB cranksets if you don't like that one.

https://www.universalcycles.com/shopp...hp?category=64

Hope this helps.

True you have to consider the RD capacity too. If the bike has a 105 short cage he'll have to go to a
105 long cage or a MTB derailleur to make best use of the triple. Even with a 105 long cage some combos would be unusable.

Thanks for all the feedback. I found this topic fairly confusing at first, but now after looking around researching everything out, I think I finally understand what I'm going to do.
What I've decide is to go with the Sugino XD600 triple crank and switch out the small chainring with a 24t salsa chainring. I will then put on a shimano 105 triple front derailleur (should i go with mountain bike derailleur?) This way it would be a 46-36-24 and my 12-26 rear. My gear inches would be 103"-24" which i feel pretty comfortable with (I'm young, i can handle it) I don't think i would need a new rd because it would be (46-26)+(26-12)=36. Also, are there much difference in the square taper BB's? I was just going to go with a mid range BB. Does it matter too much?
What do you all think?

You could just get the Sugino XD2 500 triple crankset. If I am interpreting other posts correctly, it is cold-forged instead of hot-forged and already has the rings you want.

https://00eda5d.netsolhost.com/cranks.html

It really isn't clear why cold forged is better; but a bunch of old curmudgeon buds of mine seem to think that it is an advantage.

Mid-range Shimano would be fine. These seal cartridge BB are easy to install and remove (unlike the older version which required lots of force to remove the left side). Personally I bought 5 or 6 Nashbar branded square BB when they were on sale for $6 and use those. So far I've not had to replace one yet. Check spindle length needed -- I think Sugino recommends 113mm spindle lenght for their triple XD crank. I use 115 length with mine Sugino crank.

P.S. I recommend the Sugino XD 300 ($54 aebike.com) rather than the XD 600 ($94 at aebike.com), a little heavier (no problem when touring since bike and gear heavy anyway), but has steel rings which should last longer than alloy rings on the 600.

The Sugino with a 24t ring is a great choice, its almost becoming the touring default. Sheldon Brown says you need a 113 to 118 mm BB cartridge, but I've found 110mm works well on bikes with straight chainstays. I use one on my bike set up as a 42/26 wide double using the inner two rings, so you can see how flexible it is.

Do you have a 105 long cage rear derailleur on your bike already? If so things will work out well.

It sounds like the OP added up his chain slack range to be 36, and believes his derailluer has enough capacity to take up the slack. But even if he only has a medium cage 105 rather than a long cage 105, he would still be OK if he stayed out of small chainring/small cogs combinations.

Yes if he doesn't "cross the streams".....I mean cross chain he'll be ok, with less capacity in the RD department, but its a bit of a shock if you forget.

That Sugino XD500 crankset with the old logo on it looks very nice. I didn't realize that some of the Suginos came off the shelf with 24-36-48 rings until Invisible Hand and you pointed it out. I notice that in one place in the Velo Orange ad it says 24-36-46 and the other place 24-36-48 for the rings on the crankset. On Invisible Hand's link it says 24-36-48. I like that 24-36-48 combo better than 26-36-46.

I'd get the XD300, same crank as the XD600, but cheaper rings, and replace the steel rings with bright shinny TA rings of your choice. Also the Sugino Impel is an option. It uses the 64/104 BCD which gives a
nice range for touring.

If I had to choose just one crank it would be a TA zephyr, 110/74 or 56 BCD, you can use either the 74 mm BCD or the 56 BCD just inside it, not both, but good luck finding one. I wish Sugino would do a knock off of
it!

You need a JIS square taper bb for that sugino crank, not ISO. I recommend a Shimano un-54, or better yet, un-72/un-73 if you can find one. Sugino and Tange make good ones too. Nashbar has one right now for $10 (68x110,113,115). Phil Wood makes one but expensive, need cup tool too.

https://www.nashbar.com/profile.cfm?c...tom%20Brackets

Also, I second the idea of a Sugino xd300 (all steel rings) over the xd600 (all Al rings). Replace the 46t steel ring with a 40-42-44t Al sugino ring for ~$20 - you end up with the durability of steel for granny and middle rings, and most of the weight savings of the xd600 crank by swapping the big ring for Al. Plus save $20 bucks and have a spare big ring.
