Single speeding a Campy hub?

Post by lune ranger »

Any idea how I might turn a Campy Record hub into SS without replacing the freehub body?
Don’t see any kits available like there are for Shimano hubs.
Just want to dip my toe into the water so want to keep spending down.

Velosolo.com

Spacer kit + cog - job done

Edit: unless the spline pattern is different, then you need to get a cog from elsewhere, I think

Because you didn't type "single speed cog campagnolo" into Google? ;)

To be fair - it returns different results, this morning, so may have been different when you were looking

Is it more complicated than filing new slots into a shimano cog?

Yeah... Campag slots are much taller/thicker and complex (well slightly more than Shimano) enough design that you'd not wanna try...

Bought the kit. Will go SS on my CX/commuter to give it a whirl.
18t sprocket. I have 36, 38, 44 and 42t rings to play with.
The commute is nearly 50/50 up/down with as much as 16% gradient. No harm in trying it out..... I hope.

He has sliding dropouts.

As it goes I’m gonna start with the 38t. I can’t imagine it’ll be too small for the hills and I’d be happy to freewheel down :grin:

I experimented on todays commute Luke. First major climb of about 10 to 14 percent over at least about a half mile. Went up in 34 front and rear of 19 or 21. That was within mile 2. After that the remainder of the commute i stayed in 50 big cog up front and didn't go lower/easier than the back ring of 21 (5th ring from smallest on an Ultegra 11 to 34 eleven speed cassette). Surprisingly I managed it all enjoyably with some pedal stomping.

In ratios thats, 1.62 lowest and 3.3 hardest (I tried to not use the hardest gear to emulate my 1x setup)... Not sure if thats of any help but, IMO, if you're doing roady then go harder than what you think... :smile:

I've never understood why anyone would ride singlespeed on the road. Fixed yes, but not singlespeed.

i ride singlespeed on the road all the time, where i live is very rolling with no climb longer that 3 minutes, so riding SS i can essentially do intervals, ride to start of series of climbs with a decent cadence of 85-90rpm but little resistance to warm up, get to where the climbs start, and attack climbs out of saddle, and the roll down, attack next climbs etc, which i can't do fixed. Or if i am just go for longer ride during winter.

I would always ride fixed if i was going across city on commute, makes track standing etc easier

Firstly I can SS my bike for £25. Fixed involves much more investment.
Secondly I don’t understand why you’d wanna go down a long hill with 10-16% grade at 6.30 am on your way to work and not have a freewheel.

+1 ... I'm always confused as to why one would wanna put themselves through such difficulty (the whole idea of fixed and not just the 16 percent downs). Fixed is my idea of torturing yourself be it on off or on road...
