What's your favourite gear ratio?

Put up a wanted ad (if you haven't already) on the forum and they normally go for a fiver ish, for halo ones. Or sometimes you can get em for free if someone's got spares

I'm still looking for a ratio that'll challenge and build strength. But cheers still.

Have done, thanks!

Who knows, 52/16 might even be manageable, I'll find out when I ride the fifteen miles home from Victoria after I pick it up!

Baby Varno rides 66" around town. Are you looking to be stronger than her?

Yes.

Well actually not a clue, this'll be my first foray into fixed, so its all untraveled road until I actually try to figure out what's doable.

Getting the 19T on the back will give you many more skid patches for tyre rubbertomization.

I went with the 48/19 recommended above and it's not caused me one single moment of 'I wish I hadn't done that'. Quite the contrary.

42/17
48/19
52/21
~65 GI. All good. Do it, be happy.

This has probably been posted here many times before, but it's useful, so here it is again: Gear ratio calculator

And there are set tables to read off against.

Yeah the site I linked is useful mainly for comparing cadence & speed at different ratios.

Ok so ended up doing about twenty five odd miles on 52/16 as I was enjoying myself. Verdict: doable but my knees feel funny now.
A nice person contacted me and offered me a 43t chainring which I recon I'll go for, nip it in the bud, right?!
On the plus side the wheel is fixed/fixed so if I want to I can gear up again later on.

Can always take a link out the chain to fit if need.

Today I have been mostly changing up to 64/12 on the RollerFort, up from 57 but also up from 160mm cranks to 175mm, so only 2.6% more gain.

Hill-climb season?

Foot-speed is the new sweetspot?

Or just keeping followers of the "approved" thread guessing...

Foot-speed is the new sweetspot?

Something like that. I've been running about 95rpm/160mm on the rollers for TT pace, but 85rpm/177.5mm on the TT bike, so I should be closer to road loading on the rollers now. The 64T came off the tandem, I'll get a 68T for that in time for next season to give a bit of head room as we were already pushing @umop3pisdn 's cadence on 64/16 on a good day. May need an 18T sprocket if Stewski has a go, he's more of a spinner.

Recently got back on the bike after a couple years out. Currently running 48/17 and on the few rides I've been on (few nasty hills) I've really struggled. Will changing to an 18 make a noticeable difference, don't want anything too spinny...

18 or 19? Can't handle the hills anymore! Not too bothered about number of skid patches..

18 should be fine, although 19 is the perfect ratios.

Cheers, gone for the 18. See how I get on..

56/14 is being trialled... it looks nice at least.

Do you only ride down hills?!

Embra

Highly ineffective tho.

Hope you got a front brake in the very least.
