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

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

Do Not Buy This Under Any Circumstances

ConsAppalling build quality, disintegrates after 80 miles.
I bought this a few months ago, seduced by the 'quality upgrade' pitch. I fitted it to my vintage 531 bike just before this year's Eroica... and the thing completely broke after 80 miles. The shaft was still correctly engaged with the hub.... but the rest of the freewheel was floating all over the place. Luckily a course mechanic had a spare - one of those 'cheaper' ones – and got me back on the road. But he was amazed at how the IRD freewheel had come apart. He threw it in the bin, saying it was completely unrepairable.

SJS – you really shouldn't be selling this junk, let alone recommending it.

Very peed off with my wasted £40 plus pounds.
SJS Customer Service:
Hi, Thank you for your feed back. I am sorry to hear your cassette broke after so few miles, we have sold hundreds of IRD cassettes they are normally very reliable. If you had returned the failed cassette to us we would have sent it back to IRD for analysis, they would no doubt have sent through a replacement.
Great Product

Prosexcellent product
The freewheel provided on my new bike had a ridiculous 34 tooth to 24 tooth drop. Consequently the 32 to 28 drop was a huge improvement. Excellent customer service, delivery and price.

13-32T option?
01 Sep 2019
You list the IRD Classica 7 Speed Freewheel with a 13-32T option but it's not available as a buying option on your drop down menu. Is it out of stock?

unfortunately, we do not stock the 13-32t option.

What chain would you recommend using with these, please?
04 Aug 2018
fitting to 82 yr bike with original SR Sakae chainset. Should I just use one of the listed 7 speed chains or something more upmarket?
Yes, we would recommend a 6/7/8 speed chain.

Can I Use This With My Campagnola C-Record Hub?
17 Jun 2017
Hi there - 2 questions really - 1) will this screw onto my C-record hub, which currently has a Sachs 7 speed freewheel which I want to replace 2) is the centre to centre spacing between cogs 5mm?


These freewheels use the same thread as the old Sachs freewheels so it should thread onto your hub without any issues. The spacing between the hubs is indeed 5mm.

Is The 13 - 32T Option Available?
30 May 2017
In the description and on manufacturers website and in review, the 7 speed, 13- 32T is mentioned, but buying options does not offer this? Can you obtain it?
Hi currently (31/05/2017) we can not get the 13-32T.
Is This A Compact Freewheel G
26 Jan 2017
i.e. will it fit on a campaign 126mm rear hub to replace a standard 6sp

This 7spd freewheel will sit wider than a standard 6spd so may not fit. This freewheel is 34mm wide so it would be worth you checking the space available to see if you can fit this before you purchase it.

How Much Does It Weigh?
24 Jan 2017

The 13-28 ratio weighs 457grams on our scales.

Will This Screw On To A Mavic Road Hub?
11 Jan 2016

Providing your Mavic hub has threads that are 1.370" x 24 TPI then this freewheel should screw straight on.

Required Space On Axle?
26 Jun 2015
Hello Can I use this freewheel with a ratio 13/32 on a wheel with 130mm axle? 37 to 38 mm seems to be the limit? Best regards Ulf

You should be fine using this freewheel with your set up as it only takes up 34mm of width.

Have A Shimano Mf Tz21 7 Speed Freewheel
11 May 2015
Will I be able to change my Shimano MF TZ21 7 Speed Freewheel to this? Looking for a 7 speed with a easy "granny gear"

Most freewheels use the same thread, including those two. The only issue you may encounter is you may have to re-adjust your rear derailleur to account for the different range.
