Hello

I'm building up the Jimmy Saville gold Mtrax as a singlespeed. Lazarus was a singlespeed, god rest his soul. :cry:
Unfortunately, my gold Mtrax has vertical dropouts. I sold my tensioner to Pickle, where it's now doing sterling service as I understand it. So no tensioner, but lots of aincient, not particularly special mechs.
Has anyone taken an old mech and made it into a tensioner? Did it work? Do you like it?

its too late in the evening for me to post pics but i have some where the lower jockey wheel has been removed from a mech so its just the upper and i even have a pic of a canti used

theres the option of using a lower chain device which i think is neater , certainly would make taking the wheel out less hassle

i think i even have a pic of a urethane block used to create tension

sram mechs are the best! you run the chain under the top jockey wheel and use the b stop screw to set the tension. the rest of the mech can then be cut off if you need to...

the canti arm is a really neat solution.
