Lightest / Best Compact Crank

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Lightest / Best Compact Crank

Looking to switch out my 175 Dura-Ace crank on my Scott CR1 for a
172.5 compact crank.

Any thoughts for a good compact crank? I've read about the FSA cranks and the
Pulsion cranks and thats about it.

Any info would be helpful. Thanks and have a good ride!

I got a Time ASX Titan recently and LOVE the crank. Check out pics here:

http://bikeforums.net/showpost.php?p...6&postcount=56

It is an integrated BB crankset and weighs ~620 grams complete. That puts it at one of the lightests cranks out there... but it also has tested as one of the stiffest as well. It is in another league compared to my FSA SLK mega exo piece of junk. You can get them for about $630 at some online retailers.... less than that if you know the right people ;-)

Shimano R700. I put one on my bike awhile back to replace the Bontrager/Truvativ compact that it came with, and I absolutely love it. Reasonably lightweight, very snappy power transfer, and I have not had a single shifting problem since I put it on. One of the best changes I've ever made to my bike.

The Shimano compact is a nice crankset.... but at 840 grams it's hardly light weight as the OP was asking about. That's 100 grams more than his current DuraAce setup.... still the crank is cheap so it might be worth the weight addition.

If you are using older 9 speed DA, the Ritchey compact is octalink compatible and installation is a breeze..

ya i've heard the shimano compact is pretty sweet although i'm currently running a dura-ace crank so i'd like to get something a bit lighter or at least the same weight.

when is shimano going to release the dura-ace compact crank?

If you want something lighter than or equal in weight to your Dura Ace, forget looking at the FSA mega exo cranks. Both the K-force and the SLK are WAY heavier than the Dura-Ace. Although a lot of people like the Pro Carbon cranks they make. They are ISIS compatiable and I beleive come in compact bolt patterns as well.

There just isn't much out there for compact cranks that aren't crazy expensive, yet fairly light weight. You can also take a look at the KCNC cranks. Several people over at weight weenies have triend them and all seem happy. They would come out to just about the same weight as your current setup and cost around $300..... maybe a bit more by the time you get an ISIS bottom bracket (the KCNC one is light and nice).

I think Shimano's seeing how the R700 does before they commit to the Dura-Ace compact crank. Based on how popular the R700 is, I think they might have one soon. I mean, they have a Dura-Ace triple. I recently installed a R700, and the shifting is very smooth. I waited for a Shimano compact crank because of the problems my wife had with her Strong-Arm crank on her S-Works MTB (bright orange one from years back). We tried everything to get it working smoothly, and I finally found out from a mechanic that that crank just didn't shift as well as the Shimano one. Of course, non Shimano cranks may have improved a lot since then, but it wasn't worth it for me to chance it.

Dura-Ace FC-7800 175 mm 53-39 2005: 779 g
FSA K-Force Mega Exo 175 mm 53-39 2005: 790 g

(from Weight Weenies)

The total weights look pretty close to me.

I've found most Dura-Ace 7800 cranks come in about 740 grams. Two friends of mine weighed +/- 5 grams of that figure, with the BB included. One K-force compact I weighed came in at 805 grams! (175mm). I've also seen some posts on WW with K-force weights coming in around the 800 gram mark for the compacts. I think FSA has been slipping on the weight marks lately.

I still really like the Carbon Pro Elite compart. They weigh in about 515 grams minus bottom bracket. Pick up a Token or KCNC ISIS bottom bracket and you have a nice light crank that isn't too expensive.
