Re: 30 teeth sprocket for 8 speed Campag cassettes

Following on from MickF's thread about headset spanners, I'm inclined to investigate laser or water-jet cutting of sprockets. I imagine I could get quite a few cut for the price of an IRD freewheel.

Has anyone looked at this? What grade of steel would be best for a 30t rear sprocket?

Re: 30 teeth sprocket for 8 speed Campag cassettes

Have Campag MTB (Centaur) cassettes/freehubs got the same splines as Campag road components?

Re: 30 teeth sprocket for 8 speed Campag cassettes

resurrecting this thread - has anyone looked into what's involved in modifying Shimano sprockets to fit Campagnolo freehub splines?

Re: Fixed gear chain wear

My Dad, who used to race in the late 1930s, told me they always trained with a 47t chainwheel and a 19t rear sprocket (both prime numbers) fixed setup (~66 inch gear). I've also read that prime number cogs are favoured, to prevent bald spots on tyres, by bicycle polo players and trick cyclists who s...

Re: Derailleur Hanger alignment tool ?

since I'm happier with just a spare wheel than any tool I can buy, it says much about a) whether I'm a bad workman and b) the quality of the tools that are available..... :mrgreen: Putting up with any slop in the pivot when it is easily avoided just seems crazy to me. cheers It's quite easy to use ...

Good point. You'll need to see how much clearance there is between the inside rotating bits of the chainset and the frame. If you lose 5mm, will something hit the frame?

Re: Now it's the front derailleur

The Shimano FD-M590 derailleur looks like the cable pulls the other way compared to what you have currently. Even if it's compatible with the current shifter, this may involve you in a lot of cable re-routing, fixing and setting up. Why not do the "right thing" :lol: ? Shimano sealed BB un...

Re: Tyre Pressure for Small Wheel Tyres

I'd say no. I run my 700C at 100psi, topping up at about 90. I have a small wheeler (20") with modern rims and Schwalbe tyres. First time out I automatically pumped them up to 100 psi - never again. Any little uneven surface, even just the top dressing irregular, was enough to make it feel as ...

Agreed, a sticky should be up to date. I don't think it's any more work to update or remove the links than it would be to un-sticky it.
