Consjump from 24 tooth cog to 32 tooth cog
Prosdifficult to find a 11-32, 7 speed cassette
Though I am happy that I was able to find a quality 7 speed cassette, I am somewhat disappointed that the jump to the 32 tooth cog is from a 24 tooth cog. The picture does not show this much of a jum

Proseasy to fit, smooth gear changes
oosBought this to replace an old cassete on my Trek 2100 7 speed racer. I t was easy to fit and the gear change were super smooth eventhough I am using 19 yr old downtube shifters. The changes up and down are faultless and virtually noiseless. No misses, clunking or grinding. Great item and cheap as chips. Just goes to show you dnt always need top end gear.

Can I use the 11-32 with Shimano 105 1055 bubs?

Do I need to change the 7s Shimano 105 1055 Rear Derailleur in order to use the 7s 11-32 cassete?
Thank you for your enquiry. According to the Shimano website the matching RD-1055 rear derailleur is a short cage which will only accept a cassette with a 28 tooth large sprocket so you would also need to change the derailleur to enable you to use this cassette.

Can you recommend a chain please ? Thanks

Hi there,

The best 7 speed chain that we have is part #15271.

Are The Ird 7 Speed Cassettes Splittable?
22 Aug 2016
I have a 90's era Orbit Gold Medal with a Veloce / Sachs Neos mix. The old Neos 8 speed cassette has campag spacing on a Shimano-type free hub. That's long gone so I'm currently running seven Shimano 7-speed cogs with one old Neos one that was still serviceable. It works okay but I'd like a lower gear than the 28 tooth allows and I rarely need the 11 tooth so if I could split the IRD cassette I could insert the 28 tooth between the 24 and 34 cogs in exchange for one of the smaller ones. Does that sound do-able?

As the 5 largest cogs are held together by 3 small allen key bolts in theory you should be able to mix up the ratios if you wanted to, but it is not something we have ever tried so we don't know how well it will work.

Will These Replace A 7 Speed Uniglide Cassette?

on a dura ace uniglide hub

Unfortunately this cassette would not be compatible as it is a Hyperglide fitting rather than Uniglide. We don't have any Uniglide cassettes I'm afraid.

Are These Threaded Or For Cassette Style Hubs?
31 Mar 2016
If Cassette style, which hubs will they fit ? Thanks

This is a cassette that is designed to fit to cassette type hubs so slides on and fits with a lock ring. They use a Shimano style spline so will fit to any Shimano 7spd freehub bodies or 8/9/10 spd freehub bodies with the addition of a small spacer which is SJSC part 3888.
