  • SHIMANO CS-HG20 7-SPEED CASSETTE 12-28T

    The Shimano CS-HG20 7-speed Cassette works beautifully thanks to its ultra lightweight design and HyperGlide precision engineering which ensures that all of the teeth work perfectly with the entire gear system. This makes shifting smooth and sublime, just like you'd expect from Shimano.

    Rated 3 out of 5 by cs-hg20-7 cassette Bought this cassette from Halfords Stafford branch. It has finally struck me after three or four trial fittings with and without an additional 1mm spacer, that the reason it will not tighten properly is that the Lock Ring is missing. It should have been included in the box but the shambolic storage arrangements had allowed staff to interfere and lose it. The lock ring on the HG41 currently fitted to my bike will not do the job. (the 11 tooth cog is a tooth too far for me). 28 August 2016
    Rated 4 out of 5 by Cheap cassette I was recently given an old Raleigh seven speed road bike from 1990. The gearing was a brutal 42/52 at the front and 13-23T at the rear. I needed to lower the gearing and this was a cheap option. I would have preferred to go to 32T on the rear, but the original, short rear mech may not have coped with this. I fitted the new 12-28T with no problems it worked perfectly with the existing mech. When this one wears out, I may buy a higher spec cassette. 27 May 2016

    Rated 5 out of 5 by Good if you can get one! Best value cassette on the web and can pick up at local store. What more can you ask? Well you can ask for the website stock levels to be a true reflection of those in store. You can also ask that the store puts aside the one you actually ordered. Having said this the staff in store did their utmost to rectify the situation including an offer to hand deliver the item the next day. In the end I came away with a £5 voucher and reordered on the website for pick up next day. 30 July 2015
