Presumably a skip would be a broken tooth somewhere on the crown and/or bevel gears Post pics, very curious to see what the inside of those things look like, and if there's any plastic parts in there

Every so often I think I want a coaster brake bike But I live in such a hilly area that I need the quick flick backwards into a power pedal position so alas I shall never have it

Since I’ve been training for half the winter on my new SB20, I kind of want to get a power meter for my road bike(s). One of them is an Ultegra crankset, Stages has remanufactured left side R8000 meters in stock, but I seem to recall some discussion about Ultegra power meters being not so great. Or was that the meters from Shimano themselves? My other bike is a FSA BB30 crank so that one is going to be a bit more expensive.

The left side tends to be better than the right side, but it's the design of the crank arms that's the main issue not the design of the power meter per se. On shimano, the best and most accurate dual sided power meters are pedal based. I use Favero's offering(s), and aside from them being a bit spinny when clipping in they're light, accurate and easy to use. Pedal power meters are also trivially easy to switch between bikes, so the FSA crank set is not an issue there unless you're wedded to your current pedals.

I was originally going to go that route, but I ride both bikes fairly frequently so I’d want two sets of pedals. I keep one bike in the office and ride it every morning. The other bike is weekend riding or for rides on my day off / when I work from home. I’ve tried the “carry equipment back and forth” thing and always ended up just buying two of everything since I’d invariably end up getting home and realizing I left my lights at work for the weekend. I ride SPD pedals, is Garmin pretty much the only game in town there?

You can also hack the Assiomas, but it's a hack rather than officially supported.

LordOfThePants posted:I seem to recall some discussion about Ultegra power meters being not so great. Or was that the meters from Shimano themselves? You can get an accurate estimate if the shape of the arm can be well approximated with a mathematical model. So the more beamlike it is, the better the approximation will work. Non-drive side cranks work pretty well here, so Stages has a relatively easy job of it. When you're measuring strain on a driveside crankarm shaped like this: The model simply can't give you an accurate number at all points around the pedal stroke -- the asymmetrical spider arms will stiffen and reduce flex in ways that vary from person to person depending on pedaling motion. So Shimano fudged the estimation function and just let it ride, leading to high single digit % errors. LordOfThePants posted:I ride SPD pedals, is Garmin pretty much the only game in town there? There's SRM: https://www.dcrainmaker.com/2021/03/srm-x-spd-power-meter-in-depth-review.html And some less established brands. kimbo305 fucked around with this message at 15:30 on Mar 22, 2022 |

The SRAM rival power meter is pretty affordable if you're not looking for serious-business dual side power meters.

Is there a cheaper or more realistic option to get a 165mm Rival 1x XPLR groupset than to buy a $2k State 4130 bike and take it off? Even grey market SRAM is either not available, especially the brifters, or marked up pretty substantially.

Samopsa posted:I would say most dutch style city bikes fit "Toyota level reliability". 30+ year old bikes still running fine with minimal maintenance. Especially those with a fully enclosed chain protector, no gearing (or 3 internal gears), and back-pedaling brakes. The only thing that'll need fixing are tires wearing out or getting punctures. I have a bike with a belt and an IGH and grenaded the IGH in under 6 months. If I'd spent rohloff money instead of shimano di2 money it probably would have been fine I guess :/ But that's more Land Cruiser than Toyota. EvilJoven posted:Also chain protector doesn't do really anything all to lengthen the life of a chain it just hides the fact that it's rusty as gently caress and needs lubing. It's the fact that it's a heavy as all gently caress single speed chain and there's no wear enduced drop in shifting performance that makes it last longer. Modern, full featured dutch bikes with gears and front brakes and suspended saddles and poo poo break alllllll the time. The older ones are reliable because there's nothing to go wrong. dema posted:

I ended up paying well over MSRP to get my shifters, because I am dumb and impatient. Edit to clarify: I did the 'just buy the groupset' and should've bought the whole bike.

Can you find an even cheaper off brand / old model / tiny person sized TT bike to take the groupset off? I only mention the latter because I’ve seen 105 and Ultegra groupset Cannondale TT bikes (old model, 40 something frame size ) for like £500-600. Not gonna work for a 1x groupset, but there could be some old stock in a shop somewhere in a weird size (or with a poo poo fork) that’s on sale.

Correct. My CX bike is getting long in the tooth (QR Disc, post mount) so a $2k state bike for the groupset and a $600 open mold frame seems pretty reasonable.

Everything says sold out, but the backorders don't take all that long. edit: I haven't put together the 2nd gruppo, maybe I should just sell it to thirsty ebay-ers. osker fucked around with this message at 01:58 on Mar 23, 2022 |

The first go-round I got it from Colorado Cyclist -- whatever estimates they give you are pulled from their rear end. poo poo eventually shows up. The second go-round I got it from RJ Bradley (they are just a nice shop in MA that lets you order from their distributor) and Backcountry (I know we shouldn't order from them but they had some random bits I needed to round out the gruppo).

bicievino posted:Did they increase your reach along with the narrower bars? Yeah! Basically, my entire position is much more aggressive, because planking daily works who knew I used paint to make an image of all the changes because I have nothing better to do and/or am high on endorphins. Old values on top, new ones below. NB: the old saddle angle was inaccurate; my seat came loose out riding last Saturday so I quickly tightened it and afterwards guesstimated its old position, which could very well have been -7, -8 or -10°, definitely not more level than -6° though. Each of these values had an optimal range for my measurements, but I will receive those by email at a later date. Also note that the grip width says something slightly different on the sheet I received, so that value might be off. On mine it basically says handlebar width, but the 432 mm is what the fit tool read rather than the 440 mm my old handlebars actually are / were supposed to be. e: Interestingly, I've been riding for 3 years and never had any knee issues until a few weeks ago. Just the one knee, and very minor at that. I started messing around with my seat height for the first time ever and ended up moving it up by about 7 mm, which I thought was a lot. Then today, it went up another 8 mm, whoops.. Lex Neville fucked around with this message at 22:30 on Mar 23, 2022 |

I'm not 100% what you mean by flat, but I believe it's the angle between the incline or slope of the hoods and levelness. I think that's what you're saying, so yes
