Hi all,
I have a Shimano 10 speed triple crankset 105 series 50-39-30 knocking around - I won a shiny new Ultegra Groupset for my roadbike recently so this is surpless to requirements, the rest of the drivetrain was old and knackerd but have only just bought the crankset.
I was thinking of using this on my 9 speed Hybrid set up with MTB drivetrain as the current 48-38-28 is too low as I mostly use this for commuting by road to work (Shimano Deore XT front Derailleur, 9 speed Deore LX shifters, 9 Speed XT Cassette, Deore XT Rear derailleur). I phoned the Shimano tech support and they told me no (as always) and as usual gave me a whole list of additional parts (amounting to a complete drivetrain) that I would need to replace basically telling me that Shimano 10 road and 9 speed MTB is not compatible or recommended full stop but it may work, when I asked for a reason, throw ratios, tolerances etc - I was told that was all proprietory info.
Before I go and spend $30 on a new BB and spend a saturday afternoon of time trying in vain to make it work does anyone know if there is a valid reason why it won't work or whether it is just the usual Shimano sales pitch.
Regards
Jon
