Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

UPgrading cranks- overkill for single speed urban commuting?

the bike: cannondale capo 2010
the ride: urban commuting, strictly single speed
the crank: "lasco" stock crankset on the capo, taiwanese brand, china made, CNC machined, 130 BCD, decent looking (sugino messenger style), rather strong but poorly finished (black finish on teeth coming off...)

As per bikeradar review (http://www.bikeradar.com/gear/catego...inset-10-36966) it is good enough for commuting, yet upgrade fever being part of the fun, I am considering changing the crankset...
I might add wanting to par the bike specs with the frame quality is as important as improving the performance / longevity of its parts...

contenders are:

- Sugino RD2 Messenger
- Miche Primato Advanced
- Sugino 75

Trying to convinced myself that besides satisfying a purchase/upgrade craving, it will indeed improve my daily commute...

Any thoughts?

Anybody used Lasco crank for a long time?

Upgrading to 144BCD track cranks to commute is such an overkill...unless you are racing on a track, there's no reason to upgrade to any $200+ cranks.

Well, they are an aesthetic upgrade though.

Err the paint/ finish on chaining teeth are supposed to come off....

If you insist on upgrading; go for omniums.

My only experience with a Lasco crank is on my BikesDirect Motobecane Messenger, and its chainring was badly out of round, resulting in very uneven chain tension. Even when I replaced the chainring with another better one, chain tension was still uneven. The cranks are very heavy and poorly cast, and you will definitely see an improvement with any of your listed choices. I think the Sugino 75 is overkill, and the Sugino RD2 is a good choice for the price. I have these on 3 different bikes, and am happy with all of them.

If you have money you really need to spend on your bike, get some really nice tires. Cheaper than a crank and you'll notice more of a difference. Cranks are pretty far down my "upgrade list".

I know, that's why I said 144BCD cranks...should've been more clear on my part.

Seems way overkill to me too and yet wouldn't a 144BCD be a more tangible upgrade as the ride would probably be substantially different than another 130BCD from another manufacturer? (what do I know...)

As per the aesthetics, the Sugino 75 have my vote, price notwithstanding...

noted for the paint, thanks;

omnium is also over 200$; is that better than Sugino 75? is stiffer always better?

thanks for sharing, no need to say RD2 is in my budget; anything more would be a stretch...

i keep that in mind! Any recommendation; I am riding the stock schwalbe Lugano... which are just okay (loved the panaracer tserv on my badboy, but seems that the 700x23 are not for sale anywhere...)

Yup and that's with GXP bottom bracket and chain ring (although I would not run the stock chainring for commuting).

where do you find it at this price?
hard to find down here in europe below 300us$ for the set

on another matter would it be safe buy second hand cranks that have been used on the track on ebay?

you can find used sugino 75s for ~$150, and brand new omniums for $165 on bikeisland.

for commuting, a crank upgrade may not be necessary, although i do not know how good/bad your current cranks/bb are. look into the sram s300 gxp, it's a 130bcd crank with gxp bb; i do like a stiff bb area when i ride and some of the low end square taper cranks may flex too much.

The cranks themselves are not going to get worn on the track (just get a new bottom bracket)

Another disadvantage of "upgrading" to 144 bcd on a commuter is that you are stuck with 42T and above for chainring selection.

If you're planning to ride during the winter you may end up wanting a shorter gear. I run 38x22 when I'm dealing with snow.

I'm running eigthinch cranks. They are nicely machined, light, and very solid. Pair that with the coupon from a while ago and... BOOYAH!

Buy the nicest cranks you can afford, even if they're "overkill" for this bike. When you eventually upgrade your frame (you know you'll want to), you can transfer them to the new bike.

(Arguably), I don't think crankset like Sugino 75 would be overkill for the Capo frame; i meant overkill for my use: no track riding, no fixed gear, just singlespeed urban commuting, 20miles a day, plus weekend rides in the park with the kids...

I am now running 46x16, and was thinking to get 48 or 50, then buy a couple of cogs to be able to adjust the drivetrain to the ride/weather/mood/knees...

We don't get much snow in Paris... 42T and above should be plenty I guess...

Fair enough. Also keep in mind that freewheels aren't super easy to come by in sizes bigger than 22T. Obviously I have no idea what the terrain and weather are like in Paris, so if you can never imagine wanting a gear shorter than 42x22 then feel free to look at the 144 bcd cranks.

If you're already considering the RD2s though, the 130 bcd is one more tick in the "pro" column.

a smaller bcd will be lighter and have cheaper rings.
