wheelset freewheel compatibility.

Postby koshari » Mon Apr 14, 2014 8:33 pm

hi,

we have an old commuter my wife likes at the beach, we would like to replace the wheelset (old heavy 27" buckled and rusted) with a cheap ally 700c wheelset,
the bikes effectively worth nothing however we like it,

do you think these reid griffin singlespeed wheelsets will accept a freewheel?

may the rear wheel require slight dishing?
have a set of 28mm tires to suit them so the cost of $40 is bearable.
i suspect looking at the thread on the rear hub the freewheel will screw straight on to the hub.

cheers.

Nope, It's designed for a single sprocket. Having multiple gears the freehub would have to be a lot bigger.
Maybe look at a recycling centre, at mine there are tonnes of wheels and $5 each


What cassette does it have, and how many gears? eg, 8 speed shimano

not living in the city bicycle recyclers are few and far between round here,
Having multiple gears the freehub would have to be a lot bigger
a lot bigger in which dimension(s)?

I would imagine both would be 1.375" x 24 tpi ISO thread for the freewheels to screw onto the hub?

if the spacing were able to be satisfied possibly a little dishing may all thats required providing it fits in the dropout spacing?

is there something else i may not have considered?

it doeant have a cassete which is why iam looking at freewheel hubs/wheels.
and its 7 speed converted from 5 btw.

The axle will be long enough to bolt up to a 120mm spaced frame, not the 126mm that yours is likely to be (some 5sp wheels were 120mm too, but if you converted to 7sp...)

So you'll need a longer axle & axle spacers (on the drive side, for the multispeed freewheel to clear the stays) plus a redish. Given the cheap hubs in these wheels, the axle is likely 3/8"x26tpi not M10x1, but you'd have to check to be sure.

And you're going from ETRTO 630 to 622 (27" --> 700C), so your current brakes might not reach the smaller diameter rim.

Above is correct.

Longer axle, more spacers, redish, address brake reach issue and you're done.

Brakes might be ok, you might need a long reach caliper.

yes the brakes on it appear to have the adjustment and they do look pretty long reach, , i had considered this but when the difference in mm is spelt out it looks like 4mm adjustment is required which iam pretty sure i can get.
given it has friction shifters also its not a big deal for me to throw a 6 speed on it as well to keep it below 120mm.

thanks for the quick reply folks, this gives me another project to throw on the to do / in-progress list,


EDIT: DOH, they are sold out!
