I was looking to replace a lost perl izumi forest green fleece jacket that was da bomb when I found this. When it arrived with another small item, I had doubts that both items had shipped. Okay, it's light. Fabric thickness -- nay, it's not a fabric but I'm at a loss to say what's the material and neither do the labels -- is about that of a trash bag. Advantage over a trash bag is, it won't flap in the wind -- at least not the part around the middle. It fits tight for a large -- tight under the arms, tight around the shoulders and tight around an older guy's too-big middle.

If you're thinking anything like ripstop nylon, think again. This ain't it. I have a fine nylon jacket that might do just as well. "Full length zipper vents heat" -- uh, yeh, if it's unzipped. And then, rain is coming in. It's a basic zipper up the front. Vents heat when removed, too, by that measure. Not as if it has vents anywhere else. It's a basic waterproof shield, but too tight to fit over even the lost pearl izumi forest green fleece zip up, or any other layers, not to mention middle-aged mid-section that gets a bit oversized after a few months away from aggressive daily workouts.

Still weighing whether to return this one. Not impressed. I might find it useful in an XL, but I'm overall a bit disappointed with Perl Izumi and much of the bike industry swapping out colors and products every year -- such disappointment triggered by the inability to replace the best bike jacket I'd owned with something similar. Didn't they get it right last year? Creating jobs for fashion designers and marketing people? Great, you got some of my money. I did my part. And I outsprinted some younger commuter on the way home without blowing a valve in my main fuel pump. At my age, it's the simple things that matter - the rest can seem a bit frivolous. I might be more please with myself wearing a trashbag and duct-tape rain cover in the rain.

Couldn't beat the price on this crankset. I picked it to replace an old Sugino Mighty for which rings aren't widely available, much less those with newfangled shifting technology.

Out of the box, I wasn't that impressed. I'd not spent a lot of time looking at Shimano's cranksets and was surprised to see the hollowed-out backside of the star. That makes a great place for dirt to accumulate. And how could that deep, complex concave shape possibly be aerodynamic? The ultralight bottom bracket felt like a plastic imitation of a pro part, as did the hollowed-out spindle. That split in the left crank, with two bolts buried into recesses seems like it introduces a whole new set of opportunities for dirt to gather. I mean really, does everyone who likes a light, fast drivetrain spend the requisite amount of time cleaning their bike over a period of 20 or 30 years that these parts can be useful? Does my bike really have to be either a well-maintained racer or a no-time-for-maintenance-ride-in-any-weather commuter? Not if I have a choice in the matter. Gotta love that 20th Century engineering for durability and ease of maintenance.

And what's with the 8-spline crank arm adjustment cap? Has Shimano ever heard of a T60 torques pattern? Sure, the BBT-9 fits the dust cap, but the BBT-19 looks like a more professional tool and seems less likely to damage the 16 splines of the ultra-light outboard BB bearings, especially if the cups were seized a bit tight after being left in for a period of years and someone had access to neither a bike shop to do the job right nor a bike stand available to stabilize the bike during repairs. I wonder if Shimano makes a tool just for those dust caps, but the BBT-9 is the one that comes up most often in online searches, and the neither the specs nor the picture do a great job of explaining the latest trend in dust caps. Sorry, I know I shouldn't have slept through at least the past 20 bike shows, and didn't pay close attention to the "8 spline" phrase in the tool description, nor look at an exploded view of the crankset before I bought it, but I'm just sayin...

Installed and on the stand, I was still unimpressed. The sealed bearings of the Shimano Ultegra BB-6700 don't glide like old-school ball bearings -- not even those of an old BB with years of neglect. Fortunately, I know just enough bicycling science to recognize that bearing resistance is minimal compared to other factors -- especially rotating weight. With the new bottom bracket, compared to the old tapered spindle and steel cups, I lost about 134 grams - 15 percent of the crank weight, much of which is rotational weight. A 10-speed chain dropped another 20 percent of chain weight -- also all rotating weight.

It took a while to get the old Suntour Mountain derailleur bent back into shape so it wouldn't knock the chain off the right side in any gear combination, but once that was under control, it was time to find out what I'd bought into. Would I be able to feel the difference? I wouldn't know until I tried.

Once on the road, my opinion started to swing the other way. Not sure how much of it was reduced weight and how much of the difference was the more stiff crankarms, nor just how much less overall flex comes with the shorter Q-line fulcrum of the outboard bearing location, but it was definitely different. And of course it solved the chain-dropping problem I'd intended to fix -- that mostly because it was not bent like the chainrings and perhaps star arms of the old crankset. Not only did it end the mechanical stops to put the chain back, it shifted so smoothly with my well-adjusted derailleur and downtube friction shifters, I occasionally wondered if I'd shifted or just found my second wind.

With a set of Ksyrium Elite wheels that made the folks at one LBS cringe when I showed them the bike I was outfitting, this old roadbike is now fast as lightning. Speed is good, but for an older rider who can get aggressive, a drivetrain easy on the joints is also important. Overall, I was happy with my purchase.

As I worked through the gears during a few rides, I wondered if I'd have been happier with a compact crankset. I use a 34t rear cog, and find myself there slightly more often than I find myself in the 12t, which suggests my range is centered toward the low end of my gearing preference. However, I don't like to spin fast at high speeds in vehicle traffic. If there's any time to mash, that's it -- when one wants to maintain a very stable posture but still keep up speed. If it was available, I'd probably buy just the right side so I could switch from compact to full size chainrings as it suited me, but it's not so important that I'd buy another Ultegra crank at the regular price for the compact rings.

Oh, did I mention the excellent customer service at realcyclist? Sorry, LBS -- maybe you need to recruit me, cuz these online folks have the edge in that category for now. Maybe they're just not as threatened by customers who update their knowledge by shopping. Maybe the LBS mechanics-slash-salespeople need to keep moving through service tickets and have little time to chat about parts choice -- especially when they don't have those parts in stock. Maybe it's easier to come off as friendly when they have more inventory to select from and maybe it just makes them seem friendlier when they can say "free shipping to your door" rather than "pay now and come back next week after we unpack our shipment." I suspect, though, that it's easier to critically discuss after-market parts choice when there's no risk the conversation will be overheard by a nearby customer considering the new bike purchase that could make or break that day's sales.
