Mix vintage chicken legs with a living at the top of an incredibly steep hill and.....:giver:

25T 143.6grams 1/8"chain that's a BIG cog! Brand-Dkicks

Hope it works out for you, it looks like a decent cog. There is a part of me that thinks bigger chainring and cog might make for a more efficient drivetrain but what the hell do I know.

Whatcha running for a chainring?

I like spinning low gears, but even with a 52t 'ring that's going to be less than 60gi. Just the thing for downtown hillclimbs.

Went from 46T to 42T..

Maiden voyage in 10mins. I'll report back.

The vintage chicken legs made the hill. I'm going to try bringing the legs home with me on a 20T.
82 cadence is about ~10mph, so 20T will speed things up a bit.
Had fun, last time on a fixed was ~40years ago.
Did 17 miles this morning. Mounting with cleats is going to need practice.

EDIT: Rather than going from 42x25T to 42Tx20T I've gone 46Tx25T
I'm building up slowly. Plus the 20T cog is not nearly as shiny!

EDIT2: With 46x25 installed "the" hill (from hell) was reattempted.
With fresh VCL* going at full blast... I made it, but only just ! 42x20 is not in the cards any time soon.



*VCL = Vintage Chicken Legs :)

46T x 25T to 42T x 20T
 

Originally tried 42x25 = Way too slow, I just can't pedal that fast. "The" hell-hill was very do'able.

Just did the same 17 miles on the 46x25 .... that was fun! Held high cadence all the way at an avg 12mph.
Still on the RPM limiter, it causes the engine to cut out with drastic leaving the saddle results.
But at the end of the ride, the VCL's * did make it up the hill from hell.

Already changed again, this time to 42x20 another 10% increase in the gearing.
Tallyho .. VCL's get ready!

Being this is my fist fixed in almost 40 years, I having so much fun with it.

All the best

Edit: 42x20 did 17 miles and made the hill-o-hell. Surprised myself.
