I'd say you have a set up issue you might want to look into. I ride rolling hills so I'm shifting up there all the time and have never dropped a chain on an ultegra compact.BMC Lover said:I have 13 bikes with all the set ups.
For the record the R600 may be on paper the 4th tier crank BUT it does not drop chains!
Ultegra compacts do!In racing this is a vital improvement.
IMHO it is the most under rated crankset on the market.
Only marginally heavier too than Ultegra 87 grms!
