Need some feedback on this.
Wanting to retrofit my 91 Paramount for hill rides, the 110/74 Polyvlant from Velo Orange seemed the perfect (and cheapest) fit.
Then I saw the 118mm BB requirement.
It weems to me this would render the oem double front derailleur unuseable as well as throw a curve in the chain deflection (The OEM spacing of the 7 cog rear is 126)creating a whole host of issues.
The gist I get is the Polyvlant compact double was origionally a triple that VO converted to a double (hence the bash guard out front and the disclaimer about the 46t being a middle chainring vs outer)
Am I correct in my eval. that this 'compact' would require a triple fd and a ton of tweaking with the chainline and downtube shifter (this is a sis setup)
