comment Can I modify the gearing on a 2009 Jamis Aurora?
Went to LBS #3 today and they were much more helpful and clearly informed. The person I spoke with was confident a 26t would work, but recommended adding a chain watcher (is this the same as a Deda dog fang?). He said 24t might work too but would be pushing it. Either way he said 3 or 4 cogs in the back wouldn't be useable with the granny, but they're redundant with the middle ring anyway so no biggie as long as I'm careful. Now I just have to figure out where to find a steel 24t or 26t chainring...

comment Can I modify the gearing on a 2009 Jamis Aurora?
Just stopped by an LBS to ask them to swap the 30t for a 26t, but after much hesitation, they politely recommended against (read: refused) going out of the specs for the rear and front derailleurs and recommend a different rear cassette instead. I stopped by another LBS afterward to get a second opinion - they said it wouldn't be an issue without a second glance (or a close look at the bike, really), so it kind of worried me. I might try a 3rd one later this week to see what they say. I'm not against going out of specifications if folks who have tried think it would work with minimal hazards.

Thank you! The crankset is already a 50/39/30, so I wouldn't need to swap out a 52 - only the 30 (which I take it is also called 'the granny'). Are you recommending changing both the rear cassette and the granny, or do you think the granny is a sufficient start? I'm not doing a lot of loaded touring yet, so I will likely defer a major overhaul like that until down the line.

Thanks for this helpful comment. Would I have to switch out the whole cassette or is it possible to switch out only the 32t sprocket for a 36t? I've been using Sheldon Brown's gear calculator to try to quantify the difference and it looks like keeping everything else the same, but switching out a 32 for a 36, would give me a gain ratio of 1.6 on the 30/36 gear -- which is identical to what you get at 32/26, and only slightly higher than the ratio on the 32/24 combo (1.5) (or respectively, 22.5 gear inches v 21.9).

Thanks for the helpful edits! I don't have a point of comparison, but I haven't had a lot of difficulty braking on the way down.

comment Brake cable housing doesn't attach to lever
Thank you for this detailed information! By cable stops, do you mean places that the cable should run through/mount along the frame? If so, I think you resolved the problem. There was a small stop on the front of the frame below the handlebars that is apparently meant to hold the cable housing. Once I ran it through there, the brakes started to function. They're not perfect (I think now they just need minor adjustments) but they actually work. Thank you for this!

comment Brake cable housing doesn't attach to lever
Hi there, thanks so much for your response. No, the lever does not pull any cable through the housing, and the brake calipers do not move at all. There is a little bit of motion in the cable but it's not like the pull in the rear brake -- I think it's just caused by moving the cable a bit when I move the lever.
