Good Afternoon All,
I'm currently looking at getting one of the 2018 Cannondale Synapse, Ultegra - specifically this:
I've ridden a number of Synapse models and have wanted one for a while but am after this one now due to the new tyre clearance on this year’s model.
My question is about frame size. I'm 6'2" or around 188cm and have quite long legs but not really long arms. I've ordered in a size 56 frame to try on the advice of my bike shop, but while I was waiting for that I tried a 58 frame in another shop.
What I found was that the 58 frame was initially causing me to overreach, but this was corrected when the saddle was moved forward and could be further corrected with a shorter stem.
The concern I have with the 56 frame is that I will need to raise the seat post quite a lot and then can't really raise the bars any higher as they already have a few stack rings in place with the intention to allow serious racers to drop from the default rather than raise. I generally prefer a more upright position.
I can't decide if I should go for the smaller frame and potentially suffer a too aggressive race position or the larger frame and possibly just buy a new, shorter stem. There is a 2.9cm standover difference between the two sizes and I think the 58 frame would be better in that respect.
Does anyone have any advice that might help me rationalise a decision before making the final call after trying them both again? Thanks!
