Hi guys
Thanks for looking at my post
I've only got into cycling less than a year so dont know too much appart from tightening brakes but after reading up quite a bit and watching videos on gears I feel even more lost, especially after reading
http://www.parktool.com/blog/repair-help/rear-derailler-adjustments-derailleur
Basically my wheels got stolen so I ordered new wheels and the shop fitted a Shimano Alivio CS-HG20 7-speed cassette with the same number of sprockets as my old rear wheel cassette which was stolen (SRAM 12-32) . As the wheels I got were for 8/9 speed the shop fitted a spacer so that a 7 speed cassette would fit
My question is do I really need to adjust the Front derailed at all? And do I need to mess around and change the L and H settings as it seems to be fine already, my only issue seems to be that 3 and 4 gear seem to jump and the other gears dont sound like the use to. Is it that I just need to adjust the tensioner or do i also need to adjust the B screw adjuster
Or have I just purchased the wrong rear cassette as I got a shimano cassette instead of a SRAM cassette? Does that make a difference
Ps the specs of my gears before wheels stolen are below only difference is the rear cassette
Cheers
Shimano EF-51 EZ Fire shifters, Shimano front and Shimano Altus rear derailleur, Shimano FCM141 chainset, 48/38/28 tooth chainrings with chainguard, SRAM 12-32 tooth cassette, 7-speed
