Playing with ratios
Firstly apologies for being a complete newbie!
I came about a lovely old Merlin road bike about half a year ago and have enjoyed every second of riding it, and am planning on taking it with me on a tour across Europe this summer. My only worry is that my ratios aren't all that great for climbs, especially when carrying weight.
Not being an expert, i can't give you the model of any of the components but my best insight is:
-6 speed cassette 13-?
-2 rings on front 42-52
both derailleurs are campagnolo.
After reading several other posts on here i'm pretty confident that the front derailleur has plenty of space for changing the inner ring to a smaller size... although i'm not sure quite how to match the chainrings to the crank, other than the knowledge that it is 5 arm...?
If i were to replace the cassette would i need to stick to the 6 speeds or would the derailleur accomodate a larger range?
Any help would be greatly appreciated. Sorry for my ignorance!
