Multiple bikes here with Wheels Mfg adapter BBs. No issues over 3 years and easily replaceable bearings (upgradeable to angular contact and/or ceramic as well, and the angular bearings are very reasonable). OTOH, nothing but issues with regular PF30 and BB30 bbs.

As for Wheels Manufacturing, I went with one of their PF86 BBs in my bike, and I have been very happy with it. The mechanic who installed it also was quite impressed with the quality. He had not installed any Wheels Mfg. BBs, and said he'd probably start recommending them to people.

I really like the purple one, but the fork doesn't do it for me (same with the pink, really.) It just doesn't look that good, in my opinion. Shame 'cause if the whole bike was purple it would be quite stunning.

Re disc brakes and axle standards. My LBS buddy has been test riding a Cannondale Super X cross bike for a few days and loving it. This bike has a standard 142mm rear axle but requires a specially dished rear wheel. Jeez people, what's the point of having a standard if you're going to do that?

it's basically <1 turn of the spoke nipple to fix that.

the issue crops up as a solution to better chainline and more clearance, as both the # of gears people are using and the width of tires have increased in the MTB world. cannondale has been doing this with their scalpel and flash for a while. not surprising it made it over to other disc bikes.

the zipp 11s zOMG-this-wheel-has-to-be-re-dished issue wasn't too dissimilar.

while there is an attempt at axle standards (haha), there isn't one re: frames in that same way.

I wouldn't be surprised to see something like this eventually spread to road bikes as well, as we keep adding cogs to the rear cluster. 11-speed is really pushing the limits of wheel dish on road spacing right now. A move to 135mm might keep that at bay on the road, but then there are chain stay clearance and chainline issues, potentially. I guess we'll see what happens. I really thought the 131mm 11-speed spacing was going to be a temporary stop-gap, like 128mm 8-speed wheels in the early 90's. We'll see what happens when 12-speed comes along, I guess.

Edit: I might be misremembering - possibly the frames were 128mm, not the wheels. I was like seven years old, so I wasn't paying that much attention.

I like the current Castelli aero race jersey. Sleeves are a bit long, but I guess that helps the aero gains. The newest San Remo (3.2) incorporates this jersey and the newer bib shorts, so that's a double win.

I'm still troubleshooting my SRM, sort of thinking out loud here.

Battery is soldered in properly, checked that a few times. 3.6v (new battery) at circuit board connection spots.

Can pick up cadence when swiping the spider with the pick up (crank off the bike). I've done that twice now, once earlier today. This is a spare harness that I have, not on the bike.

When placed lightly on BB spindle can pick up cadence with harness on bike. To see the computer head while I'm at the BB I have to unravel the wire a bit and let the computer head dangle next to the top tube.

Tightened crank, checked again, computer still dangling next to downtube. I could transmit enough force to display both cadence and power.

Put bike in trainer. Put computer on bar mount. Turn pedals. No cadence (and since no cadence, no power). Nada. Nothing.

I'm going to see if twisting the (brand new) harness does anything, etc. Also going to check with a different computer head.

Castelli San Remo. Juniors fav of some 8-10 brands. You can do more aero with a pure skin suit, but I understood you were looking for a more RR type thing.

Harness or pin connector, my best guess. Likely one of those wire things where if you hold it just so it makes contact.

I hope it's just one thing.

New harness, same symptoms with another harness, same symptoms with another head (tried 2 heads, 3 harnesses of which 2 are new). When the head dangles on the top tube the pin connector has some side load on it and it worked.

Arg.

Maybe it's time to upgrade one to wireless.

Anyone have a solution to mount a light on aero road handlebars?
Our Wednesday group rides are edging on sundown this time of year and none of my lights will mount on my Giant Contact Aero road bars...

start with tate lab univesal mount. it's clunky, but seems to do the job (i use it on my Zipp Vuka Sprint aero road bars)

Some of the lights come with a stretchy rubber strap for mounting, instead of the round plastic bracket. The one I have works fine with my 3T aero drop bars. Don't remember the model off the top of my head, will try to find out later and report back.
