Hi
can anyone help with a tech questions regarding gears.
I have a peugeot professionnel which I only use for excercise, its in mint condition , a bit dated but is does for what I want. I am getting on in years and have difficulty getting up hills.
The current gearing set up is 52/42 front and shimano hyperglide 13-23 on the back. I have ridden the bike with a 52/38 front and can get up hills OK but the back mech is too short to make full use of the 38 front ring. A 28 tooth back ring with a 42 chainwheel gives the same theorectical gearing so should do the same job. The back mech is a short cage shimano rx100 am I better changing the back cassette and keeping the 42 chainwheel which is generally ok or using the 38 chainwheel and changing the back mech. The problem I have is I can,t find out if the RX100 back will cope with a 28 tooth back sprocket.
The obvious answer is sell the bike and buy a new one with a triple but I dont have that sort of cash and could not justify the £700 odd for a new cannondale or similar.
Any help will be much appreciated
