Hi, I am a newbie to this forum. Like etigge post above...

Love to hear if any bro/sis have done that and hopefully can provide feedback about the ride with this combination.

Am eyeing the Dahon Vigor P9 to upgrade to 105 5700 shimano group-set however with a Tiagra SL4600 flat bar shifter as 105 does not have a flat bar shifter.

Regards

Kel

Hi dannygeni, read in the internet that for upgrade try not to mix roadie FD & RD with MTB shifter like the alivio. How abt the 9 sp cassette ? Hope you are using a roadie cassette with the Sora RD. If you want to use the MTB cassette, might want to check if the Sora RD can reach the lowest gear on the cassette.

Wow, nice bike. Congrats..How's the ride ? Will check this bike out.

Hi Jackylim87, good to hear that. I haven't checkout the bike yet but have finally committed on the Vigor P9 and will be doing some upgrade on my own. Will follow similar path that etigge & Dannygeni have done but at a slower pace ...haha (due to "kena kumpul wang" again after the Vigor P9 purchase.

Once again congrats on your new bike.
