I have an 1994 Cannondale Killer V900 bike that I am trying to convert to a commuter. The Chainrings are 22*32*42 (94BCD, 5bolts). I am considering changing the 42t to a 44t.
My questions are: 1) Can I find a steel 44t, 94BCD, 5bolts chainring anywhere; 2) Considering that the 42t on there now is a Sugino alloy, would steel 44t clash with the 22t and the 32t alloys; 3)The Shimano LX front derailleur is the original circa 1994 that came with the bike, and I am wondering if the LX derailleur can, with adjustment, take on the extra 2teeth jump that it will be asked to do, without any strain; 4)Do I need new chains? or will the new 2teeth jump work with my present chains sized for the 42t big chainring?
If it helps, I run 12/28, 7-speed cogs, and the bike has an XT rear derailleur.
By the way, I am thinking steel 44t b/cos I understand they last much longer than alloy chainrings, and I am not terribly concerned about weight.
I know some people will think that I should just get rid of the bike, but I am the original owner, have some sentimental attachment to the bike, and paid close to a thousand dollars for it in 1994. Moreover, I just do not like selling stuff.
Thanks for your help.
