Hello out there!
I am the proud owner of a shiny new 2013 DownTube 9FS, and newbie to biking in general. I ordered the bike online from DT directly, and took the bike in to my LBS for tuning before riding it (about 2 weeks ago), and everything seemed to check out fine. I rode a few blocks to my apartment right after getting it back from the shop, once more around my neighborhood the next day, and then for about a mile, maybe less, 2 days ago without any noticeable issues. Yesterday, I took it for a much longer ride (about 7 miles total), and noticed my gears were seriously slipping. I tried to be conscious of not pedaling while shifting gears, and that didn't seem to help. Today I checked out the instructions for adjusting the derailer on DT's website, and followed all the steps. The gear shifting seems much smoother (though I haven't ridden it again yet), but now the bike won't go past 7th gear. I can shift up to 8 & 9, but the chain just stays on 7! No problems with lower gears. I've adjusted the cable tension, and the H & L screws several times over, but nothing seems to work. It's possible that it may work itself out once I ride again, but I'm dubious since I can't get it to do that by just spinning the pedals. Any help would be greatly appreciated!
