I am refurbishing a 1976 Raleigh Record Ace and need a new rear mech.
The chainwheels are 52/42 and the new cassette I'm buying is 13/30 - hub spacing problems have been
sorted out! Rear mech requirements are thus capacity 27, max sprocket 30.
Shimano rear mechs have capabilities as follows SGS type: capacity 43, max sprocket 34 GS type:
capacity 37, max sprocket 27 SS type: capacity 29, max sprocket 27
Thus I appear to need the SGS type by virtue of max sprocket size; however the SGS is a large
mountain bike mech which I would prefer to avoid.
Will I be able to use a GS type despite the apparent max sprocket , bearing in mind its large
capacity (37) compared with my requrements
(27).
Can anyone advise me?
