I am considering buying a Giant 2003 OCR frameset, I have
seen this frameset fitted to the 2003 OCR 0 bike but it
has a triple chainset, will the frame be desinged
specificaly for a triple chainset or could I use a double
chainset groupset from my current bike without any
problems with alignment etc?

TIA

The frame is not specificaly designed to work with a triple
or double - you can fit what you want,1,2 or 3 rings.To use
a double, you may need to fit a shorter bottom
bracket.Triples generally have longer bottom bracket axle
lengths to take account of the larger width of the
chainset.The std. BB will certainly work, but the alignment
will probably be out by about 3mm.Its no problem if you are
mainly using large front/small rear gears, but once you
start hitting the hills, the chain is going to get a little
twisted. Alan.
