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
- 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 / 19 / 21 / 24
- 13-28T = 13 / 15 / 18 / 21 / 24 / 28
- 13-32T = 13 / 15 / 18 / 21 / 24 / 32
- 14-32T = 14 / 17 / 20 / 24 / 28 / 32
- 14-34T = 14 / 16 / 20 / 24 / 28 / 34

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

ConsOverpriced, unreliable, finish doesn’t last
ProsLooks good
The first one lasted about 15 months and 1,200km on a bike I use only occasionally. The pawls broke. SJSC contacted IRD on my behalf. IRD refused a warranty replacement. I bought another one. That one developed rough bearings and the nickel plating flaked off after 18 months and 1,000 km. Replaced by a cheap Shimano freewheel which has been fine.

Prosgreat quality and looks
Truly a piece of craftmanship. Looks good and I love the sound of the spring. This 34T freewheel in combination with a classic 39T front chainring got me about the same range as a compact crankset on a modern bike. Helped greatly to get me up the Mur-De-Huy last weekend. Also, it just looks great on a classic road bike. So from a bike that was only usable for crits and flat roads, it's now a mountain eating machine!
Questions & Answers (16)
Can I use this with a 80's Campa Super Record Hub
26 Mar 2019
The hub has Italian thread, will the 14-32 work with the Campa super record derailleur (now having a 28 fitted with a 53/42 crankset and this works fine)? Best Robert
Hi there,

Unforunately this part is only Shimano Compatible.

Do I need a new chain and/or add 6 links if fitting the 14-34 to replace a 14-28
03 Jan 2019
the derailleur is Shimano 600 Arabesque with 52-42t Sugino mighty chainset. should all these work ok?
We doubt the 600 derailleur will be capable of working with a 14-34t.

Thanks - 08/01/19
Is the Classica freewheel offered with a French thread 34.7x1?
16 Nov 2018
These are only available in ISO Standard 24 x 1.375.

Thanks - 20/11/18
will this freewheel work on a 120mm track wheel? does it require a shimano freehub type hub?
20 Aug 2018
I have an ultra (5mm) spaced 6 speed schwinn supersport from 1983. it is a narrow frame. I need to use 120mm track wheels in order to upgrade my wheelset. The track wheels typically come with a freewheel, not a freehub...
Hi there,

Unfortunately we do not stock that bike so wouldnt know whether it would fit or not im afraid.

A true screw-on cassette?
30 Jul 2018
Hello! A straight-forward question to avoid misunderstandings (on my side of course). Is this really a classical, old-times-screw-on-cassette, the way they were in the 1960s? All the cogs in a single block? Thanks.
Hi there,

This is a screw on freewheel, all the cogs on a single block.

1980`s Raleigh Montage gear replacement?
15 May 2018
I have replaced the useless rear brake from behind the BB with a Diacompe centre pull mounted on the rear stay and am now moving on to gearing. I have a Sakae 28, 38, 48 Oval chainset and Sunrace 12 to 28 6 speed rear which I would like to replace to make the hills easier (I am 67), will this be a straight replacement or will the derailleur and Sunrace shifter need changing as well
This should go on as a straight replacement, but if you are changing the ratios you will need to check the rear derailleur is suitable to handle the larger sprockets.
With reference to the 6 speed 32-13 tooth gear assembly
26 Apr 2018
Before I buy what seems to be what I've been looking for for ages, please could you tell me the diameter of the 32 teeth gear ring so that I can make sure it will fit my old but much loved Dawes Horizon tourer.
Hi there,

130mm is the out diameter.

Replace an old Sachs 13/32 7 speed.
27 Nov 2017
Thanks for the answer

'We stock a 7 speed 13/32T IRD Classica freewheel, the part code is - 37004R1332' which is good news if its not wider than 34 mm.

Can you tell me the width of 37004R1332 please?

The width is roughly 33mm.

Replace an old Sachs 13/32 7 speed
26 Nov 2017
I am trying to replace an old Sachs 13/32 7 speed from my '92 Dawes Tandem. The width is a challenging 34 mm which means an 8 speed is out of the question at 39 mm. This product looks attractive at 13/32 but is a reduction to 6 speed. The description also says 7 speed though but you cant dial up that option. Is there a 7 speed 13/32 available?

upgrade for screw-on shimano 5-speed freewheel
26 Jul 2017
I'm looking for a 32t 5- 6- or 7-speed freewheel to replace a 5-speed Shimano MF-ZO15 screw-on freewheel. The bike has 126mm spacing. The current freewheel measures approx 30mm. It looks like there is more space on the hub (Miche). I can send a photo if you need one! Do you think this would be compatible?

This 6spd freewheel measures 32mm, so if you think you have the additional room for an extra 2mm then you should be okay to fit this freewheel as a replacement.

6 Speed Gearing Optons
21 May 2017
On the IRD website the only gearing option listed for the 6 speed is 13-28. Although I am able to select the option for 13-24 on this website, and it is listed as in stock, I am wondering if you actually have it or if it is just a mistake. I did not believe IRD made a 6 speed 13-24.

IRD make these 6spd freewheels in 5 different ratios all of which we stock. These include the 13-24T option.

Is This Ok To Use With Friction Shifters?
29 Apr 2017

This freewheel is fine for use with a set of friction shifters.

What Does The 34T Look Like?
29 Apr 2017
Which one is in the photo on your site, I have looked elsewhere.
Does the 34 stick out granny style like this

Our photo is of the 14-32T option. The 14-34T option jumps from 28T to 32T for the last jump so there is a noticeable size difference but it is nowhere near as pronounced as shown in your image.

Will This Suit A 126Mm Axle?
20 Sep 2016
What is the gear spacing?
Want to upgrade from a 5 speed suntour.

It will depend on where the hub is sat along the axle but you should be okay with fitting this to a 126mm spaced hub. This freewheel takes up 32mm.

14 - 34T V'S Sora Rd3400
22 Jul 2016
Hi, I Am Looking To Increase The Gearing On My Old Holdsworth Elan. I Was Looking To Replace My Starlight 6 Gear Freewheel (Which Is A Replacement For A Suntour Unit). I Assume That It Will Fit The Threads On The Suntour Sealed Hub.But Think That It May Not Be Compatable With My Shimano Rd 3400 Which I Think Has A Max Of 28T. If It Is Not Compatible I Would Apprecaite Suggestions For A Replacement. Many Thanks Jon

You are correct in thinking that your RD-3400 won't be suitable for use with that freewheel. You can however use a 9spd MTB derailleur with your 9spd road shifters fine and these will easily cope with a 14-34T freewheel. We do the 9spd Deore RD-M591 derailleur which will work, these are SJSC part number 39048.

Campagnolo Compatibity
31 Mar 2015
Would this freewheel be compatible with my 1980's scre on campagnolo hubs

Yes this should fit, the Shimano Compatible part of the title refers the indexing of the sprockets.
