I have done a search and googled it but can’t quite find the right answer.
Can road cranks that use external bottom brackets be used as fixed/ss? ie. i buy a road bike crankset, remove one ring and adjust somehow to get the right chainline.
My concern is that I dont know if/and to what extent the chainline is adjustable to acheive a ~42mm chainline. Would i need a new bottom bracket? or can you adjust the chainline/crank position with the same BB?
Cheers for any help.
Use a SRAM omnium track crankset it’s has a external bb and a tight chain line.
I agree and id love to, but I can’t afford it. I can find ultegra and 105 road sets for MUCH cheaper, hence the question.
Put the ring on the inner position, and space the driveside cup out with some BB spacers (no more than ~2mm though).
I tweaked a chainline on a SSCX with a 105 hollowtech crankset this way, worked perfectly.
Ok, so basically you have to space the bb cups to adjust the chainline?
Is it possible to use the outer ring and completely remove the 2mm spacer?
Or if you need then can they be put on the non-driveside cup?
If i understand correctly, it appears that you have to maintain the same spacing between the cranks?
Is there anything that can be done with different Bottom Brackets (ie. different widths)? or are they all standard for these type of cranks?
I am actually looking at getting some hollowtech cranks, but if i have to put the chain ring on the inside (looks real crap) or have to space out one crank alot, i may just give in and buy some crapper, cheaper square taper cranks.
If you want to run fixed you’ll either have to use a ~42-43mm chainline on the inside ring or ~47-48mm on the outside. Or do what Blakey says. The outside ring works for White Industries ENO hubs (and maybe Paul? I dunno).
If you’re SSing a freehub you can just space the cog accordingly to match the chainline at the chainrings.
There’s normally no spacer between the shell and the cup, so no, you can’t remove it and get a track chainline on the outer ring.
Even the outer ring with a White Industries hub isn’t an ideal chainline, Paul may be.
It’s served me well for many thousands of kms. Although, I’ve generally used a 1/8 chain on a 3/32 cog.
if your handy with a spoke wrench you can rearrange the axle spacers to move the hub to the right and then dish the rim back to centre. i’ve been running this setup since the start of the year without any problems, even done a couple months of track

have you looked at the sram s300 (s500?) and raceface decadance cranks? both are aimed at street riders so are reasonably priced.
