I picked up a vintage Schwinn LeTour (free from friend), which I think is around an '80-'81 (made in Chicago in headbadge). I want to convert it to fixed for my kid and have a question on he stock crank. It has a Sugino Super Maxy crank, but the large ring (52T) is permanently affixed to the crank, so we're going to give it a try with the large ring. Since the 52T is essentially one peice with the crank arm, I don't have the option of moving the ring to the inner or outer side of the crank spider to adjust the chinline. Has anyone utilized a similar crank like this and achieved a good chainline? Are there any tricks I should be aware of, eg different spindle length, spacers in rear wheel. Also, I'm going to try & re-use the stock rear wheel; re-dish it and use a lockring to hold the cog on.
If he takes to the fixed gear ride, I'll upgrade him to a proper fixed hub wheel and crank, but I want to know he likes the fixed ride first before I invest any $'s in it.
I switch between the big ring and the small ring in the Summer and winter on my Campy Athena double (20 years old now). The 53 tooth sprocket on my Steamroller single speed is my "Summer" Gear and the 42 tooth sprocket is the "Winter" Gear. I think it is a 16 tooth singlespeed sprocket in back. I have no issues with the chainline.
The issue I'm having is that with this SuperMaxy crankset, you cannot switch rings as the big ring and the crank are are permanaently attached - there essentially is no crank spider. So just asking if anyone out there has used a siimilar crank in a conversion, and if there are any tips / issues to be aware of in getting it to work with setting up a nice chainline?? I'd like to try and see if this crank will work out for starters before entertaining buying a different crankset...thanks!
