FYI this is a great time of year to get on top of the bike maintenance stuff that tends to get sidelined:
- replacing worn cleats
- replacing worn cleats
- check/replace chain if it is stretched
- check/replace worn cassettes
- grease pedals (if needed)
- check cables & brake pads for wear/alignment
You get the idea.

my cables are so dead. i have to shift by plucking the downtube cable after each shift.

Sounds like my guitar class...

Clean and lube the little routing attachment that bolts on under your bottom bracket. Sometimes that gets gunked up and inhibits sliding of the cable.

you caught me. all i did was loosen the cable and lubricate under it...didn't bother to clean them out. i tell myself it's because i wanted to buy new cables and housings. i currently have a despicable blend of different brands and colors of cables and housings. so despicable, in fact, that it only ever bothers me.dstokes said:Brendan,Brendan Rigby said:my cables are so dead. i have to shift by plucking the downtube cable after each shift.

So camp is almost here! Dawned on me I've never flown with a bike and after reading all the various posts about it, I just figured I'd borrow one. If anyone is so willing, I'll happily exchange for some beers or cortisone shots.
Jan 31, 2014 at 05:57 PM
I have a Pika you can borrow.
Jan 31, 2014 at 06:49 PM
@Owens if you want you can bring it over here and we can "pack our pikas" together. (Yes, that's a euphemism for how Dopplegangers roll. Or fly)

So, Ride Brooklyn recabled my Cannondale and Will told me that my crankset (a Quarq) was not tightened enough in my bottom bracket. Which I didn't really understand actually, but whatever...
So now I go to pull off my Quarq to put it on my other bike. I pulled off the non-drivside crank arm, as usual, after which, normally, I'd give the axl a little tap and the thing slides right out.
But now it won't budge. I've already tried the rubber mallet with as much force as I'm comfortable banging on my bottom bracket.
I've swapped that crank dozens of times, so I can't figure out what the heck is going on. Thoughts?
Note that I have GXP to bb30 adapters

Are you using Wheels MFG adapters? I've got them and definitely, I've had times like above. The fit is very tight. Good for staying in, bad for getting out. The thing to try is to lean your bike on its side to spray the thinnest lube you can (like WD-40) so it seeps in between the axle and the adapters. Wait for the seepage. Try banging again.
Jan 31, 2014 at 11:18 PM
Thx.
I think I just wanted to hear a friend say it was OK to bang.
It just feels so wrong
(And yes, wheels mfg)
Feb 01, 2014 at 04:47 AM
Mine is unnervingly tight even on my BB30's
Always feels like I'm about to do something horrible.

WD40 really is a miracle substance. Is there no problem it can't solve?
It came out after doing what JP advised. I think maybe RB just didn't grease it as much as I usually do.

Upon much reflection...I've decided to go with the Stages power meter. I'm convinced however, that the Power2max is the better meter...The P2M is really an incredible deal on a crank spider strain meter. I am also convinced that for the way I train, a Stages will be enough meter for me. It will be consistent enough to train by and improve performance. I like the fact that it uses Ant+ and Blue Tooth. I can update firmware from my iPhone and calibrate the meter from my iPhone. My Cateye Stealth 50 head unit does not have a calibration feature or smoothing...I don't want to spend another $300 on a new computer. Finally, I've discovered that the lowly Sram Rival crankset is capable of some alarming stiffness characteristics. And for a fatty mcfat like me, stiffness trumps weight savings !

not sure if this is the best thread for this question, but i am looking to buy a large (ish) spool of cable housing, and a bunch of cables. i find over time i have a few bikes a year to fool with, and it seems more efficient than buying individual cable and housing sets. i notice that one can find say a 50 foot spool of housing on amazon, but i cant seem to find a large set of shifter/derraileur cables. do we have a way of getting something that is ordinarily sold only in bulk packaging to bike shops?
Feb 03, 2014 at 04:42 PM
if you find the product code on the manufacturer's website (or by calling them), you can give that code directly to RB and see if they can order it through their distributors. i did this with a cane creek integrated headset. sometimes it takes the folks @ RB a bit to figure out if they can order it (i think the system they use is slow and tough to use).
for example, i think you might want to order Jagwire item no. 6009862 (http://jagwire.com/products/v/Shift_Inner_Wire_-_Workshop_Box). or the longer 2300mm cables? 6009864
Feb 03, 2014 at 04:49 PM
Mark Purdy iFixbyx is interested in finding people who are interested in trading their time in his shop for some instruction. Not sure how formal/structured he is yet with this, but if you have some time on your hands things might be fun.
Feb 03, 2014 at 06:30 PM
I think I got 25' or 50' of housing that was packaged by QBP. Jagwire is their cable and housing brand.

Google is not helping me answer a question about recording and viewing left/right power balance.
Power2Max and Vector pedals and I suppose SRM power meters all put out data for left and right power, which certain programs (Training Peaks and Golden Cheetah 3.0) are able to display. This seems like it would be useful for rehab from an injury, or maybe not. Anyway, my question is:
Which computers record this data, such that it can be passed on to the programs. I don't necessarily need to see it on the bike computer, I just need it to be in the file that is loaded onto my laptop computer. I'm pretty sure the Garmin devices do this. What about Joule GPS?

SRM don't do left/right power that I know of. Is there a new version?
Feb 05, 2014 at 06:28 PM
According to DCrainmaker the Joule GPS does record left / right balance.
http://www.dcrainmaker.com/2012/11/cycleops-joule-gps-in-depth-review.html
In the following section: Support of left/right power (pedal balance)
I'm actually a little surprised since none of the PowerTap powermeters can support it since they are hub based.
