I have a project frame I would like to fit disc compatible sliding dropouts to, however I need to know A) where I can get the dropouts from, and B) how much its going to cost to get them welded on (and if I need to brace the frame - its about 1994 vintage)

I know Paragon Machine works do them, but my (albeit limited) interweb browsing hasnt yielded anything - can ye help!?

big thanks, boy (the)

The good thing about the Paragon's is that the brake calliper moves together with the wheel. This avoids all kinda adjustment problems :wink:

Ceeway have Rohloff-style dropouts with various options - disk or no disk, mech hanger or no mech hanger, etc:

I think if you want the Paragons you'll have to go direct to Paragon:

But definitely find a framebuilder first, consult with him on the suitability of your frame, and choose dropouts with his input. If he's not happy doing it, find someone who is.

That's an interesting arrangement. Can you give more details?

afraid not , result of a google search where a forum had a " post your singlespeed " thread and ive long since deleted the favourite link

could be mtbr forum though if you want to find other pics , there was one other where the wheel was static and i think another of the complete bike so you could see the manufacturer

I think you may find that retro-fitting the Paragon sliding dropouts to an existing frame either means specifically resetting the seatstays to suit or living with a considerable increase (30mm +) in wheelbase.

I obtained a drawing from Paragon in order to mock-up a couple of dropouts out of thin sheet just to see how the geometry would all work out. In my case (95 Explosif) it just didn't (without a lot of work to the seatstays) and I decided not to go down that route.

If you look at the Groovy pic with the Paragon sliders you'll hopefully see what I mean - if you imaging cutting off conventional dropouts and grafting on the Paragon, the axle position will either move back or the seatstays have to be set to a steeper angle to maintain the same chainstay length.

Funnily enough I've recently had a chat with Argos cycles about the same thing - I enquired about Pauls dropouts with a disc tab.

TBH by the time you factor in removing canti bosses, the attaching of cable tie points respray etc You could easily pick up an 853 On-One.

I was quoted:

£100 fitting of Argos horizontal drops
£60 disc tab and brace
£16 removal of canti bosses
£100 spray (approx)
£8 ea zip tie points
Decals??

Just a thought.
