Added to 50.4 cluster

https://velospace.org/viewcluster?c=675

TA made 50.4 crankarms in 150, 155, 160, 162.5, 165, 167.5, 170, 172.5, 175, 177.5, 180, 185mm, so freaky sizes must have some practical application. I just saw a set of 150 arms listed on eBay, advertised as "juvenile size". I picked up a 180 driveside arm at a swap meet for $ 5, mostly for novelty reasons; I've since discovered the existence of low-tooth 50.4 chainrings, which must be either tandem timing rings or BMX.

Thanks for the heads-up!

how did you tension your

how did you tension your chain like that? i also have a SS 84 SM500.

did you use a BMX with a 1/2 link?

chain tension

I fiddled around with gearing a little and got lucky, there is no half link. much more difficult was respacing the 3 speed hub, that involved making a bunch of spacers myself since it has an axle larger than 10mm.

the magic gear... i did that

the magic gear... i did that with a GT and screamed with joy. i cant find the magic with my SM500.

my 84 is on vintagecannondale.com. you should go post it over there.
