whatcha think about using this for a fixed project?

I think it looks like a fine crankset.

what about the fsa carbon track crank set.

Sure hoping you're putting them on a nice bike. Those cranks cost more than my fixie did.

Those are the ones from Chucksbikes aren't they?

It wold seem to me that they would only justify a true track bike, and then why not just use an actual track crank Carbon or not. Although at the same time this is ME and not YOU. If it works and you're happy then do it and do it hard!

Oh, I dig, they are the only 170mm square taper on chucks bikes and they are super cheap. Yeah, go for it, they are a little clunky looking but if thats your thing then refer to post #6.

Slowly my nicer bike is becoming more and more carbon. At this point I need to switch the saddle, bars, crank and wheels, but pretty much all the other carbon-able components are carbon already (the frame is AL; but I'll keep it that way). My final goal is to have a super light (slightly less than, or around 14lbs) fixed gear that I can use in a TT I want to compete in at the end of may. If I'm going to be going up against all the crazy $$$ geared TT bikes I might as well roll in with some bling myself.

I'm interested, where around here would you compete in a TT??

compact crankset = 110 bcd (bmx) chainrings! and yeah chucks has this set for relatively cheap. what length bb would give a good chainline with 120mm rear? what is better about the 'track' model other than the name?

[edit]
• 108mm-109.5mm spindle recommended
• 43.5mm chainline

I'd get the FSA track cranks, given the option. They look very nice too.

On second thought, I'd go with some alloy track cranks The Sugino 75s are cheap and strong.

I have the OctaLink version on my multigear and absolutely love them. I'm curious though. Since yours will be going on a fixed gear, are you going to keep the 53? I'm assuming you're already planning to ditch the 39. What kind of gearing will you be using?

Most TT bikes are relatively heavy- with aero frames, a rear disk, maybe a trispoke front, aerobars- and most courses are relatively flat. I'd worry more about getting aero than saving a few grams on a crank.

i wan to to ditch both and get a 43t or a 47t.

whats with the track crankset? how come the crank arms arent made of carbon too? i dont get that design...

Its in Alliston which is at Highway 89 and 400. I'd need to find a ride out thre but I have plenty of time to arrange it.

As for lightweight vs. aero the lightweight carbon parts I would get would be pretty aero. I'm trying to get my hands on a set of spinergy rev-x wheels, and some carbon tt bars with removable clipons. This is still a bike I ride around so I'm not going to put disc wheels or anything super crazy on it.

Its a 15 km straight flat course (7.5km there and back), so I reckon I'd need to put on a big chainring, get into the most aero position I can and just keep a steady cadence the whole time. If I find an aero track frame between now and then that I can afford I might get it, but right now I am happy with my spicer fixed road frame.

Track Cranks

Its not that they are or aren't made out of carbon. Its that they accommodate only one ring and have a mounting placement that facilitates a smooth chain-line. Having said that I know very many people who use road cranks and either use the inside of the spider or the outside and get good results. It looks like a good crank, fat and carbony, if thats your thing then its a very good example of it.

Don't know about the spindle. It depends on how deep the taper is on the crank, get a BB and try it, if you cant get it to fit get another one and try that one. The Phil Wood has a reported 5mm of travel left or right, if you cant get things to line up with 5mm of travel then you have a major issue. At the same time Chucks has some nice cheap sealed BB's that may just work. I would say try the Chucks if it doesn't work keep it around and get the Phil Wood, you'll only know how much you need to work for a chain-line once you have tried one on.

I've got a similar FSA carbon crank set on my single speed with a 42 inboard and a matching Spot bash ring outboard. I have to admit that at first I got 'em just because I thought they looked awesome. But now that I've ridden them for a couple years I'd also have to say that they are the lightest, stiffest cranks I've ever mashed out of the saddle on. Everyone knows how that helps when you're standing and fighting or sitting and dying on a long hill. Simply outstanding. DanO
