Single speed gearing

Re: Re:

Unless you are a top professional cyclist, if you can get up hills with 42/17, they cannot be hills.

On road if you're reasonably fit you can get up the hills with that gear. I've ridden up some pretty big hills on my 700c 46:18 geared fixie.

Thanks for the help ,it mainly for towpaths and a few light hills.
I have a geared bike for the rough stuff..

Why do you want to change to a smaller front ring? The 32:13 equivalent will wear out quicker and will only have around 6 teath engaged on the rear sprocket.

That makes sense, will be building it with the bigger front ring then..
Thanks..glad i asked now
