Freewheel Options

peloton7000

Changed the chain on my bike last week didn't change the freewheel gears.

Unfortunately the wear on the rear is causing the gears to slip under load.

The original freewheel was HG37 14-28, I replaced it with a HG50 11-34 a couple of years ago, just to get the higher gearing.

Looking at the options available now (same as before I think) it looks like a HG37 is the best route, I never used the 34 on the HG50, only problem (HG37) is the low gearing a 14 with 48 chainring.

Any other routes available, I know that Sunrace do a 13-28 would need to get a different tool to fit that (or at least to get it off again).

Fit 52/39 chainrings to go with the 14-28.

It's often cheaper to get a complete crankset than just the chainrings on their own.

This will give you the following gears: 39/28, 39/24, 39/22, 39/20, 52/24, 52/22, 52/20, 52/18, 52/16, 52/14. That's a 10 speed bike!

A new chainset (ring) won't stop the chain jumping at the bach though.

If your cassette is 9 speed then better ratios are available:

I thought the Sunrace freewheel was 14-28 or 13-24.

any way have fitted a few to bikes and not had any come back (yet). if the ratios suite give them a go.

There's a 13- up Suntour freewheel here:

Either that or the Sunrace one combined with a larger chainring may be your best solution. Try the numbers in Sheldon Brown's gear calculator:
