It's shut. There is a cafe next to it, but the Nova is going to be refurbed.
Sorry I meant as a point for us Prestatynites to join the ride. Not as a cafe stop.

For a normal person I think it's just too steep for fixed. It's 1km average 13% (flattens out a lot after that) but according to local expert @Ootini it maxes at 27% on one bend. Hence the comp is furthest up the hill without stopping. Redeemable gift certificate at the Chippy is the prize

I asked a friend recently, how steep a hill might be managed on fixed; he told me that he once did the Winnats Pass on 54. Sorry to say, I don't know what is meant by '54', but it was on fixed.

Gear inches?

Anyway, fixed up Winnats is insane. I can just about get up there on my lowest gear; 34/25. Our hill looks about as tough so it'll definitely "who gets furthest" rather than "fastest to the top"

My friend wrote :

"Rode up Winnats on 54 " 1968 (POPULAR ratio at the time)"

I'm not sure how this gear inches thing works . . . so what size chainring is this at the front and what cog at the rear ?

Assuming a 27" wheel, anything that was twice as big at the front as the back.

So it would been like cycling up Winnats on 48/24 or 34/17 ? He said a popular gearing, so more realistically, something like 42/21 ?

He also told me, that he did quite a few events on fixed, with 81" gearing . . . So how does that work, in terms of the front chainring and rear cog ?

How do you work the calculation ?

Gear inches = diameter of driven wheel x (number of teeth on front ring / number of teeth on rear cog)

It is a measure of how big he wheel would be to get the same forward motion from one turn of the pedals if you were on an enormous penny-farthing.

Edit: @User beat me to it.

What is fixed equivalent?

I need the proper fixed guys on the ride to confirm, but I understand that typical fixed gearing is something like 48-18 (no idea really, I googled it).

So to make the Challenge fair, anyone doing it on a geared bike needs to use the closest gear they have to the "typical fixed" gearing. And not sneakily change it half way up as well

My 78 inch gear won't get me far. I doubt I would make the track crossing and traffic lights. After then it's game over as it's Winnats steep if not more.
