Carbone SL for next year's training/racing wheels, what does the BF community think? A guy is selling a set on fb for 675 and I'm thinking of buying them vs new Flo 60s.

I had some SLRs a few years ago - similar rim, but different spokes and hubs. They are rather narrow. At the time - about 2009 - they had pretty good aero numbers. They are not particularly light though. I think Mavic claims they are in the 1700-gram range, but Mavic always under reports weight, by a lot. For training wheels, they are fine.

I put wheels on my black bike (3T + old crit bend bars) to see if I could get a gut feel comparison between those and the Steelman stem + FSA bars (steel stem).

What I found interesting is that up and down, meaning at the drops, the two bars were similar. I'll say that the old crit bend bars flex a bit more but without fixing the fork in something I don't have an exact figure. But both bars moved maybe an inch or so total up and down, the crit bend bars may have moved another 1/4-1/2" total. Really, though, they didn't feel very different. Honestly I was a bit taken aback. I swear the crit bend bars felt like noodles the last time I raced on them (May 2016). And the FSA+steel felt awesome the first time I raced on them (the week after).

I kept flexing, wondering what I was missing.

I found that the crit bend bars move fore-aft a LOT. Like maybe an inch or more. The FSA bars really didn't move fore-aft at all, very little, like less than half an inch. It may have to do with the compact/short reach. The crit bend bars (and all older bars, really) typically have 11-12 cm reach. Compact bars have about 7-8 cm reach. Compact bars should be stiffer due to the shorter tubes. Up and down isn't as different because, given direct up/down forces, there's a bit more "spring" to the drop, but width/etc seems about the same. With older longer reach bars there's a lot of unsupported fore-aft spans that appear to flex more readily.

So it may be that it's not as much up and down at the drops as it is fore-aft.

I see. the fore/aft movement is probably nothing on the fsa gossamer wing then, considering it has a flatter top for the elbows during a breakaway or something. the up down flex may be more due to less cross sectional area, but I want to say that most of the flex comes from not the bars, but rather the stem/bar junction. so I usually just look for a thick stem, with a face plate that's well built, not one of those 2 piece face plates. there's a blog post about testing out different stems, and i noticed that the ones with the most deflection were the ones with thin face plates, and 2 piece face plates.

i think the ea90 stem that I ordered should be just fine.

My 6800 shifter was hungry this morning and ate a cable.

Luckily the bike shop was open and we were able to get everything out and put a new one in.

williams or racerims - both local, a few hundred for new.

Both are solid and I think SJBC gets team pricing from Sean.

Sorry if this got posted but can someone learn me on the quick differences between Garmin 520, 820, and 1000?

My focus: post ride analysis (currently using Golden Cheetah), possible integration into Strava.

Maps really aren't my concern although i'd probably use them if I had them.

Out of box suggestions welcome, like a camera that integrates a lot of that stuff for download later. Virb? I generally don't need to see any data in front of me while I'm riding, and I could set up a Sportsiiiis (Ant+) to give me parameter alerts if I'm in a mood and doing intervals.

I'm usually up for such research but right now it's a bit hard and I have zero knowledge of Garmin/computer-heads/etc.

520 - no touch screen
820/1000 touch screen

I hate no touch screen.. I've owned all 3 and currently own 820 and 1000. In my opinion the 820 is the best one to get. All the latest like crash detection and follow you riding partners (if they have an 820 as well) They are supposed to update the 1000 to include that stuff but it has not happened that I know of yet. 1000 would be better for maps for screen size and maybe slightly better turn by turn which I don't really use that often or didn't feel the 820 was bad in that respect.

I read some about the new Virb Ultra30 camera.. seems like a winner. The virb software is awesome no matter the camera, but the metrics you get with the virb are superb. I plan on getting the virb ultra30 someday down the road.

So to summarize.. 820/ Virb Ultra30.

just something to consider: touch screen is great...until it gets wet. (edited based on dz_nuzz's post, below) the new ones use a capacitative touch screen which can have problems in wet conditions. IME, even the earlier ones had some issues when wet.

also, it can be an issue when wearing gloves if that is relevant.

i've owned the 500, 800 and 520 (and a whole host of garmins before these); i tend to prefer the non-touch screen versions.

[MENTION=77814]carpediemracing[/MENTION] -- any of the 3 your are considering will give you all the data you need for analysis with GC, so unless you have some other criteria they are comparable in that regard.

if you decide on that the 520 is your thing, i might be able to get one for you.

So the 800/810/510 were all resistive touch screens which meant they were based around pressure, which made them really easy to use when wet. The 820/1000 use capacitive touchscreens (Like the one on a cell phone) so they are activated by water.

I have used an Edge 1000 as a daily driver for about 2.5 years now and I think that it deals with it's water issues really well. The 820 I have had issues with the touch screen. They recently updated it so that you can change the sensitivity of the screen as a setting which helped, but it seems to vary between "Too sensitive" and "Why won't this damn thing respond?".

My view on the 820 / 1000 decision is different from [MENTION=355518]spdntrxi[/MENTION] . I prefer the 1000 over the 820 I really like the form factor of the 820 but the unit is extremely under-powered in the CPU department (Switching screens can be very laggy, and just try having the lap summary screen up and do a crit. The unit practically freezes when you switch to the summary screen because it struggles so much to calculate all the laps). But both are fine units, but for [MENTION=77814]carpediemracing[/MENTION] you might be better off overall with the 520 if all you want are some simple metrics and camera control. The other nice thing about the 520 is that you can come to memorize the button combo you need to use to turn on/off the camera vs. fighting with a touch screen.

I have no input on the camera though.

^good to know about the laps...as I have not used that on the 820 yet. As for the screen yes mine at first was oversensitive on the 820, I could hover over it and change it. It's much better now and my 1000 never changed with water droplets.

I've had the 1000 for a while and really like it. Haven't had any issues with moisture affecting the touch screen operation (I don't ride in the rain a lot, but occasionally get caught out).

Was going to buy my wife the 820, but the 1000 was on sale for about $30 less so went for that one. Didn't realize at the time that grouptrack works a little differently on the 1000 than the 820, hopefully they update that (they've been pretty good about keeping the 1000 updated with software-only features that come out on other devices).

I like my Edge 1000, the best thing is the extra screen size so in races you can see with a quicker glance.

The biggest issue I have with it is when I'm really suffering, sometimes the sweat drops hit the screen and change the settings!

I've been happy with the 510 and its touch screen. Resistive, so it's easy to use in the wet. The only thing I HATE about it is that the mounting tabs are about 1/2 degree off center so the computer is just a tiny bit out of line. Drives me absolutely nuts looking down at it. Functionally, it has been great though.

thank you so much for adding this point -- the new one definitely doesn't work as well in the rain, which some might consider problematic. worth knowing ahead of time.

i'll amend my post above with the error.

Thanks everyone.

I'm leaning toward a non-touch screen something because I always wear long finger gloves and I often get water/sweat on my computer. I'm less concerned about seeing immediate data. I'll look to make sure it's recording, sometimes I do a heart rate or speed sanity check, but after that I virtually never look down in a race. In training, okay, more power peeking, maybe I'll do intervals again, and I seem to check my HR all the time.

I'm my winter "what do I need to get done before next season" mode. One of the things that's been bugging me is not having an Ant+ powermeter for Zwift. Also if I get an Ant+ powermeter then I can get all my data in one place. Right now I'm using an Ant+ HR monitor so my SRM isn't recording that. I feel like I need to go Ant+ to get the best data. Both my (Cannondale SI) SRMs need servicing, I think I'd ask if they can upgrade them to wireless/Ant+. Otherwise I'll realistically need a new/different solution.

The Si SRM is still one of the best power meters made. The wireless ones hold their value well. I'd definitely go the upgrade route on one of them.

I was told that my two units, same generation, may not be good candidates for upgrading. If they can do it, great. If not, then I have to figure out what I want to do.

They are the lightest crank powermeters I've ever seen. I think it's 575g for cranks, BB, wire harness, head, chainrings, everything. Also very stiff. And good Q factor.

Found the picture. 577g I think.

PBK is having sale onShimano Ultegra Di2 6870.
I am seriously considering getting it. Anyone regret going to electronic shifting, and anything I am missing? Like a better version around the corner, etc?

Thanks

there's a new A-junction (EW-90) that supposedly fit into the end of a handlebar. Much better form factor than what they currently have

well the new DA is coming next year.. I'm sure ultegras refresh will follow. I put electronic on my wife's bike since she was a beginner with small hands and not use to levers. Well I took one 50mile ride with her bike and was so impressed with it, I updated all mine soon after.

I thought that was a big deal, then I wired my A box under the seat on the 9000. don't know why I didn't do this before.

So is it worth waiting for?

Hmm.. The e-Tap looks attractive too. No wires...

I have not done much research on 9150.. but I heard it has synchro shift... I'm happy with current DA and 6870.. so I'm good.
