Hi all,
I currently have a 9 speed 11-25 cassette and a 50-34 compact chainset on my bike.
I'm off down to Provence at the end of April / early May and part of my week will include a ride up and over Mont Ventoux. Having sought advice elsewhere on this forum, I am going to fit a cassette with a lower bottom gear to help me to the top of the climb. I think an 11-28 will be OK and I'm presuming a straight swap over won't cause any issues, but I'd appreciate the advice of my learned friends on here.
My rear mech measures about 75mm centre to centre of the guide pulley's, so is this likely to be a short cage, and if it is, can you guys confirm that it will work OK with the 11-28 cassette? If I'm really pushing my luck, would it be likely to work with a 30 tooth large sprocket too? I'm not looking to replace the cassette and go to the expense of a new mech and chain just for the extra insurance of a 30 tooth, so if it would need all this I'd probably just settle for the 11-28.
Any advice will be much appreciated, thanks.
