Cotter pins for BB

I have a french fixie that i built this summer and i am in search of some cotter pins that attach the pedals to the bottom bracket. Does anyone know where i could get some QUALITY ones? The LBS i have been going to is inadequate. I am out at Penn State for a while. Thanks

via bicycle in philly probably has what you need, but you'd really be better off with a modern crankset.

Do a search for cotter at loosescrews.com - they carry 9mm and 9.5mm.

All the more power to ya... I have a french-threaded peugeot w/ cottered cranks that I finally replaced with a square taper spindle.... soo much easier to work with.

Bikes: Currently just an old GT Tequesta MTB, but just rebuilt from the ground up as a single speed and love it! Next project is a road fixie, looking for a donor....

You can get them at https://www.thethirdhand.com for about $1.00. Lots of small parts there too! Good place, used them for years.

Bikes: See my sig...

A good road double (reduced to a single) can be used with a square taper spindle... you will need a number 5 spindle to replace the cottered one and this can be done as long as your bearing cups are in good condition.

A new spindle costs about $7.00 and most good shops should be able to get them if they don't stock them.

i've never found a shop that stocks them. I got a spindle on ebay, it is a TA 344. However, it's actually too long (even though it's supposedly equivalent to a 5 series). It works, but the adjustable cup doesn't thread in as far as it should and there are some exposed threads... makes me nervous.

Do a search on sheldon's site for more info about using 5-series square-taper spindles with french bottom brackets

Seeing as how cottered cranks are "old", you might check with the Vintage forum if you can't find something to suit you.

I believe Yellow Jersey stocks these, and Harris Cyclery probably does, as two other choices. Be sure to read up Sheldon Brown's article on them if you haven't.

+1 to that. While lots of "upgrades" are over-rated, getting away from cotters can make your life a lot easier if you're not wedded to the cranks. Also keep in mind that good, used road doubles go for cheap.
