Sorry this is such a boring topic, but for this dilemma I feel I need the help of this board's depth of knowledge and expertise
So, recently I've been saving up to buy a BMC ALR01
frameset in size 54 (shiny anodised silver) and I had my mind set on it for quite a while until I came across a very lightly used Cannondale Supersix from 2008 in size 56 (gloss back with red/white writing) for a really good price and now i'm torn between the two, hence this thread. I've put together a few pros and cons that I can think of, but they seem to balance out to me, so any points for one or the other would be much appreciated. FWIW, at the moment my main bike is a B'twin Triban 540 that fits like this:
And here are the two bikes' geometries compared:
(bmc in red, cannondale in green)
Oddly the 54 BMC seems to fit about the same as the 56 'dale.
- completely new
- 2018 technology
- heard good things about bmc geometry
- ~1295g for frame, (claimed) not light, but not so heavy for alloy
- comes with a carbon seatpost
- stiffer than 10 year-old carbon?
- bsa threaded bb
- heavy fork at ~450g claimed
(seems a lot for alloy, but it looks really well made)
Cannondale Supersix 2008
- cannondale geometry
- 1050g claimed weight (probably more like 1150, but still lighter)
- 350g fork
- bb30 (lighter + stiffer(?) than bsa)
- very lightly ridden
- same front end as the system six
- 10 year-old technology
- stiff as 2018 alloy?
- cannondale's first full carbon frame (quality?)
- bb30 is harder to work on than bsa
That seems like a pretty comprehensive list on paper, but if anyone has any experience with either bike or any other points to add, they'd be very welcome.
