Larger-sized freewheels?(10 posts)

Larger-sized freewheels?Humma Hah

Right now, in order to rig the cruiser for off-roading, I need to yank off the 46T crankset/chainwheel and install my 36-tooth set. This is a mighty pain in the patootie, and not something I'll undertake at work when the guys upstairs say they're heading out to Fountainhead for a ride.

What I need is a 22 or 23-tooth freewheel I can keep in the backpack or my desk drawer with a spare chain and a freewheel puller. All I can find in this size is the White Industries deluxe models Sheldon Brown carries. Neither LBS seems to be able to get above 18T.

Is the $80 White freewheel worth it? I'm game if they last 4x as long as the $20 variety. Anyone know of another brand with lots of teeth?
how about 20?DougSloan

Here's a 20 tooth, from the special order section at Harris:

Come on, splurge and get the titanium 23 tooth...

Actually, my LBS has exactly that one in stock ...Humma Hah

... they ordered that one without noticing that it only has two notches for the freewheel puller, where most freewheels have 4 notches. My puller won't fit it, and they couldn't identify one that would. Having been warned that a chainwhip will not necessarily remove these things once they're really set, I was leery that I might be stuck with it.

20 would give me effectively the same gear I was in that day at Solvang when we met. OK for hilly paved rides, but not low enough for hilly MTB routes. 23T would give me true 2:1 SS-MTB gearing.

I think acs makes a puller has 2 prongs, but don't quote me on that.
Sheldon does have a Lifu Dicta 14/15 ...Humma Hah

... some kind of funky metric one. I have no idea if it fits the 2-notch Shimano.

The guys in MTBR Singlespeed just clued me in that ACS has just re-introduced a 22T, which would be close enough, and $20. I'd rather put the $80 into a quality 18T, which would get almost daily use and 4000 miles a year.

Will your hub accept an old 5 speed freewheel? If so you can find one with the cog size you want in the middle (or what lines up best) and grind the rest off. It's not fun work, but you can usually find tons of cheap used ones with big cogs. If you spend enough time on the grinder you can get the weight down to within' reason. I've done a few like this for budget SS conversions.

The wheel started life as a 6-speed, and I had a 7-speed on it for a while, but I've pulled a couple of spacers off to fit it on the cruiser, so I'd have to be careful what would fit it now.

Supposedly you can screw freewheel corncobs apart and replace individual cogs, or replace them with spacers, but I've never tried it. The method I've seen takes 2 chainwhips and I only have one. I probably have a 6- or 7-speed freewheel around somewhere.
they do come apart but...desmo

it's very hard, and you will usually come away bleeding! easy enough to make another chain whip, but I'd stick to grinding off the unwanted cogs. good luck.
no chain whips are required to remove frewheel cogs....ukiahb

learned a cool trick from Glenn's bicycle break the chain and wrap the upper run over an intermediate cog and the lower run over the smallest cog (from underneath), and then pedal backwards...tried it and it worked do need to be carefull as the small cog will unscrew suddenly once enough force is applied. In my case I removed all the cogs and put the #2 cog back (an 18T) and it lined up almost perfectly w/ the large chainring which made a SS...later I welded the freewheel together to make a fixed gear.
I found an answer at MTBReview Singlespeed ...Humma Hah

The Web Cyclery is again carrying the 22T ACS Claw freewheels, for about $15. They're not as good as the Whites, but good enough for the occasional off-road ride I anticipate, and only 1 tooth off the desired gearing. The website does not yet list this size, but I e-mailed them, and the 22T is definitely in stock.

I do think my next 18T for the cruiser will be one of those stainless steel White ENOs. And has those for $70.
