IRD have discovered many of you with older bikes not wanting to upgrade to cassettes, but are finding that a quality freewheel almost impossible to find. That's because all the big Asian manufacturers are only churning out freewheels for department store bikes. IRD made these purposely nice enough to put on a vintage Cinelli road bike, but affordable enough to use as a replacement on cheaper bikes with. The Classica takes design cues from the reliable Shimano 600 series.

- Index shifting waves and special teeth profiles
- Fully chrome-plated cogs
- Heat-treated for durability
- Alloy and polycarbonate glass fiber spacers
- Double row precision bearings
- Labyrinth seals
- Stronger pawl springs than on the Defiant series
- Available in 5, 6 and 7 speeds

Teeth Ratios:
- 13-24T = 13 / 15 / 17 / 20 / 24
- 13-28T = 13 / 16 / 20 / 24 / 28
- 13-32T = 13 / 16 / 20 / 24 / 32
- 14-28T = 14 / 16 / 20 / 24 / 28

Requires a Shimano type splined freewheel removal tool. (Shimano's own is SJSC part #870)

Overall Product Rating 4 / 5
Very poor value

ConsWaste of time and money
I bought 2 of these freewheels in March of this year hoping that they would be a better quality than the Shimano equivalent. After a few hundred miles the bearings became very loose and it often made a noise like a train going over points. When I took it apart for inspection the outer bearing was covered with flakes of chrome that came from the plating of the bearing cone/retaining nut. After a thorough cleaning and removing one shim to get the right clearance I thought all would be well, but the noise is still there especially when the chain is on the third cog. Very disappointed!

Consmany times more expensive than the Shimano equivalent
Prostime will tell if they wear well
I bought 2 of these freewheels to use on some old Campagnolo record large flange hubs hoping that these would be nicely engineered. Both of them were eccentric when spun round and one of them makes an occasional crunch when riding as if the bearings are dry. I'm not convinced that they are worth the money.
Nice quality item

Proswell made, brings new life to an old bike
Wanted a wider ratio for a bike from the 80s I've been renovating. This is very suitable - it gives me lower gears, changes well, looks the part & is totally silent. Very well made, too - no excessive play, and reliable shifts.

Ird Five Speed Freewheel

ConsPrice? You get what you pay for in this case.
ProsDoes what it should well.
I am about to order my third one. I use this on a Carlton fitted with Campagnolo components, and the five speed freewheel fits a treat in the rather narrow space [by modern standards] on the back axle.

I change the freewheel and chain about every second year. I have nothing but praise for this IRS unit with the 13-24 teeth range. This fits with the archaic Super Record derailleur I use, and the actual gear shifts are easy, certain and almost silent. The pick-up of power is effective, while the over-run is reasonably quiet.

I give this a five star rating.

What derailleurs work with the 13-32
30 Jun 2020
Got one of these to replace a 14-28 freewheel. Have now tried a few longer cage derailleurs and keep finding that the top jockey wheel hits the side of the big ring when in the 2nd gear. So I guess I need one with a longer upper pivot and/or hanger. I've also read about mechs with 3 pivots for large range freewheels..
What would you recommend please?!
for a 5 speed freewheel these are your best options depending on the mounting style:
ISO freewheel (1.375 x 24 TPI) on an italian hub (1.378 × 24 TPI)?
09 Jun 2019
Would that ISO threading of the freewheel (1.375 x 24 TPI) fit on an italian hub (1.378 × 24 TPI)?

This freewheel does use the standard ISO 1.375 x 24 TPI threading so it should fit on an Italian hub.
Is this a sunrace type fitting freewheel cassette ?
24 Aug 2018
Hi there,

This item and the Sunrace part are both Shimano Compatible, so it is safe to assume that they both have the same fitting.

What threading does this freewheel use?
17 Jul 2017
Is it the ISO threading (1.375 x 24 TPI) or another standard?

This freewheel does use the standard ISO 1.375 x 24 TPI threading.

Freewheel Widths
12 Mar 2017
What 5 speed freewheels do you have for 120 OLD rear hub?

Which freewheels will fit will depends on your hubs offset, the three 5spd freewheels we stock are sized between 29 and 31mm so as long as you have enough clearance for a freewheel of that size you'll be fine.

Total Width?
19 Feb 2017
What is the total width of the freewheel?. I am asking since the photo seems to indicate a 6 speed body with 5 cogs on it. It shall be used on a bike with 120mm rear spacing and as such there is limited space.

This freewheel is 29mm wide.

Is The 5 Speed Cassette For A 126Mm Hub?
09 Feb 2017

You should be able to run these 5spd freewheels on a hub with a 126mm axle without any issues.

Is The Freewheel Threaded? From The Photo It Looks Like It Is Splined
23 Mar 2016
This is for a c1984 tandem and I'm trying to lower the gearing.
Old worn out freewheel is 14 _ 28t and is threaded. Is this one compatible? Do I need an adapter??

This is indeed a threaded freewheel so should be compatible with your bike without the need for any adapter.

09 Feb 2015
Please can you confirm the centre to centre spacing fron the outer to inner sprockets on the IRD Classica 5 speed freewheel. Also, is it possible to swap sprockets.

Thank you

The spacing of this freewheel is just under 29mm. The sprockets appear to be threaded onto the free-wheeling unit so in theory they could be swapped out but as the sprockets are not available individually, it seems like a pointless exercise.
