Can I use this cassette on a 8 speed Shimano group 1995 vintage ?
27 Oct 2020
Yes, you can, just make sure your rear derailleur has the capacity to work with this wide ratio cassette.

Can i use this with Shim. STX RC 44389?
05 Oct 2020
I hoping to replace my worn 11-32T with this 11-34T, will it work with my old (but trusty) STX RC mc38 rear derailleur? Also can you advise me on a compatible chain that will run with both parts, im a little confused regarding correct chain widths..?
Many thanks SJS team.

Shimano states the chain model used with your rear mech should be the CN-IG51 chain- which is a 3/32" chain. When looking for a chain for the RC-MC38 any 7/8 speed chain will work absolutely fine.
Is this ok to use with a Deore LX cage? What chain do I need to go with?
05 May 2020
This is for a Thorn Discovery tandem purchased in 1998.
I BELIEVE you have the RD-M565 rear mech, the max sprocket size is 32, so I suggest you don't risk it and buy the Shimano CS-HG50 8 Speed Cassette - 11-32T (SJS Cycles part number : 34911) OR buy this cassette AND a Shimano Acera RD-M360 Megarange Smart Cage 8 Speed Rear Derailleur - Black (SJS Cycles part number : 44850) the SRAM PC850 3/32 Inch 7 / 8 Speed Chain - Grey 114 Links (SJS Cycles part number : 15326) RT
Fitting the cassette
28 Apr 2020
I'm looking to purchase the Mavic A719 wheelset when it comes back into stock. I'm wondering if it is possible for this cassette to be fitted to the wheelset upon purchase. Thank you
Hi, yes. Please contact our customer service team to ensure this happens when you order. Thanks 29/04/2020
Can I replace an 11-30T cassette with this one if I'm using a Claris derailleur?
03 Mar 2020
I think the Claris derailleur has a medium cage but I'm not 100% sure.
Hi, you will need a long cage derailleur for an 11-34 cassette. Thanks 04/03/2020
What does the 11-34 weigh?
29 Mar 2019
Thank you for your enquiry, this cassette weighs 344grams. I hope this helps.

11-34 derailuer question
03 Feb 2019

I am thinking of changing my current 11-34 cassette to a 11-34 one. Which derailuers would be best suited for this increase in capacity? I currently use a 50/38 on the front with ultra bar end shifters.


Si W.
While staying with the same cassette 13-34. The capacity won't change, hence the same rear mech will do the job.
Many thanks
Could you please list all the sprockets on this cassette?

Does this replace a CS HG30-8
27 Jul 2018
Replacing a worn out CS HG30-8 with an 11-32T range and a Shimano Acera deralieur. Will this (or the 11-32 version) work as a replacement?
Yes this would work, you will need to ensure your derailleur has enough range to cope with the 34t larger sprocket.
