Giant Chainring ~ 60T +

[silverlightning]

Hi again kingoffootball,
I still have 60 t TA ring with 5pin cluster as the 50t mentioned earlier,
I also now have 170ctrs cranks to suit. Any good?

Regards silverlightning.

Hi Silverlightning,

Do you know roughly how long bottom bracket they would require? I'm also restricted in how long I have available, as I need to use one of my Mavic threadless bottom brackets.

Re:

I now have a 57T Campagnolo 144mm bcd chain ring as a temporary measure, and I'll have a better idea of gearing when the bike is built up, but any larger sizes still sought!

How about a Capreo hub as another way to increase the gearing - they go down to 9T at the rear.

I'd not come across the Capreo hub before, thanks for the suggestion.

I'll see how the gearing feels once it is built up, but I have already built wheels for it with retro parts, so I'd rather stick with them if possible. If the gearing is too low to be usable though, that might be the best solution.
