You're right Stokes. So the wavy was missing. Not only that, but looking at images of my bottom bracket online I realized that the small rubber ring that rests on top of the drive side bearing between it and the inside of the spider was missing as well!

"How did could this happen?" I asked myself (as I stared deeply into my own eyes in the mirror). Where could these things be?

I dug out the crankset that came with the bike, which I replaced with the Force compact about a year 1/2 ago, and there on the axle, covered in gunk, were the ring and the wavy, basically fused to the axel and the inside of spider. Got them off, cleaned them and assume my problem will be solved (though I haven't had time to mess with the bike yet today).

How the Force compact worked without those parts for 18 months with no play or wobble in it I do not know.
I think that rubber ring is called a bearing cover. Helps keep gunk out, but may not affect function much. I also gather that there is some variability in bottom bracket and crank dimensions such. The wavy washer is a hedge. My FSA came with a few very thin washers "just in case" the BB30 wasn't built "according to spec".
Anyone feel like being an early adopter? I would get one for my TT bike if they sponsored us [via dealz].

@mugwump - more info on the Stage Cycling StageONE power meter. Seems like a cool crank based power meter at fairly low cost:

I would, though I'm waiting for the Hollowgram version. They don't have anything for road BB30 right now.
Craig,
they had a bb30 sample at interbike.  


They show the hollowgrams on their web site but no pricing or availability yet.

anyone have experience with either the cycleops brand trainer tire or the minoura dualist trainer tier?

thanks!

another quick question.

ultegra vs 105 cassettes. Is there any difference? According to some websites the 105 cassette weights in ~1 gram heavier than the ultegra. Is there any difference?



Ultegra:
  • 10-speed road race cassette
  • Aluminum carrier
  • Updated sprocket design for better shifting tolerance and more accurate shifts
  • ~ 209g



J&B Importers
SHIMANO | 105 CS-5700

Product Details
  • 10-speed road race cassette
  • Aluminum carrier
  • Nickel plated steel cogs
  • ~ 210g

I've always thought 105 stuff was a steal.
With most cassettes, price reflects materials, finish, and number of cogs pinned together.  The cheapest cassettes have the least finishing work or coatings and typically have all but the smallest (ie the 11) pinned together.  They're also the heaviest.  The most expensive have titanium cogs for the tallest and are joined by machined carriers to save weight.  In between, like the ultegra vs. 105, there is very little difference.  My guess is the finish on the cogs isn't as good on the 105, but that's probably about it.  Pros typically have mid-range cassettes on their race bikes to make sure they don't go under the uci weight limit.  Titanium cogs are not only expensive but wear out faster, so most of us would be wise to avoid them. 

One thing to watch out for is loose cogs. Because of the spline design, loose cogs can dig into shimano/sram style cassette bodies, particularly  when the bodies are touted as being light, with the tallest cogs (21-27) doing the most damage.  So these you generally want to have joined with at least one other cog on a carrier or by pins so that the digging doesn't occur.  Campagnolo-style cassette bodies do not have this problem thanks to their design.

Nope, but I do have experience with the Kenda trainer tire (co-branded with Kurt Kinetic). DO NOT BUY IT.
my main concern with the cycle-ops tire is the color.  Too easy to forget it is trainer-specific and take it out on the road.  The Continental tire is bright orange and treadless and you'll never mistake it for a road tire.

though, to be fair, one year on Keith's birthday ride, a day when the temp only went up to 22, we were coming home and a guy joined up with us near Nyack, with the orange tire on the rear wheel.  
The additional benefit of the continental orange trainer tire is that fitting it onto the rim will build exceptional upper body and core strength - ideal for cross.
@Mike.
That's a good question. I wanted an Ultegra cassette for my "climbing wheels" (don't laugh)... The 105 9 speed cassette was actually lighter than the Ultegra, we put them on the digital scales at RB. Seems to last about the same, perhaps a tad noisier. Shifting was fine. 
Trainer tire? Seriously? Does it get any more bourgeoisie than that? I am going to enjoy putting the wood to you fancy lads and your "trainer tires" this spring. Yacks
My trainer tire: an old ass gatorskin.  Works great. Low noise.

I hear those are particularly quiet when the wheel never turns :P

It's a $25 piece of rubber that never wears out, and it's smoother and quieter. I have a vittoria one and it works great. My old gator skins are on my commuters.

Wait, don't you have a $1000+ Computrainer? Talk about bourgeoisie!

At the shop we just had a clinic from the CycleOps rep - basically the trainer tire is made to last longer under those high-friction conditions, and to be quieter than your average road tire.  I think if you have an old pair of tires that are free of grit, that should be almost just as good.  The noise difference is probably minimal.

I agree with JP that it would be better if they made it a more distinctive color - you don't want to be running those trainers outdoors.
My old trainer (cyclops) worked fine with a "retired" conti gatorskin.

My new trainer (kurt kinetic) SHREDS anything that isn't a dedicated trainer tire - as I discovered via a rooster tail of tiny vulcanized rubber bits painting the wall behind me....

I was chatting with Jeff the other day when he expressed his dismay that no one makes an orange helmet.  Well -- I found one: http://www.e-rudy.com/index_inner_detail.php?group_id=3&cat_id=&item_id=HL512601US

I thought I'd share it here in case anyone wants to go for the ultimate in kit-helmet colorway synchronization.

Spiuk Daggon, Catlike Mixino are currently made in Orange. Also NOS Giro Atmos or Aeon from the period when they made the Rabobank team helmets are a good match.
I like the white helmets for a number of reasons.
  1. coolest temp wise in the summer
  2. most versatile
  3. our new kits are predominantly white
  4. white just looks classy.
The problem with a color "matched" helmet is that it really never matches the kit. This kind of graphic/design dissonance grates on my nerves when I watch Le Tour contenders with their "matching" green or yellow helmets.

Anyway, that's my opinion on the matter. But I certainly wouldn't begrudge any team members who purchased themselves an orange helmet! I'm just going to stick with white...as long as that's what Rudy wants!

I don't think I'll go with an orange helmet myself.  I am a little too tall and wide in the head so would run the risk of looking like an enormous decorative pumpkin stand.

I am in the market for a white helmet, though; seems like a no-brainer to go with Rudy, given the sponsorship/generous discount.

Is the mixino out yet? It's gonna be like $300. Good news was I got a whisper at competitive cyclist for $130 bc I guess they're making room for the new catlikes.

FWW..My Rudy Sterling helmet was a quality control nightmare. I ended up giving it away to Kissena's own Harry B.  I've never had a problem with any other Rudy product so I assuming it was something about that model and perhaps about the early production run from which mine came.
I just scored this Steven's Prestige cross frame set. 

http://www.ebay.com/itm/Stevens-Prestige-54cm-Cyclocross-Frameset-/380536508115?_trksid=p2047675.l2557&ssPageName=STRK:MEWAX:IT&autorefresh=true&nma=true&si=lU8xD8BpdTUNUx3hWvZELWVv+q0=&orig_cvip=true&rt=nc

I have a new FSA Gossamer BB30 crankset w BB included that I picked up cheap for $45. I don't know my BBs at all. Will these work together w/an adaptor? The Steven's is a press fit frame.
I cannot tell what kind of BB it has. If it is BB30, then your cranks will work. If it is a smaller size (I believe the alternatives are all a smaller bore), then your cranks will not fit. The spindle will simply be to large to go through the hole. The adapters are meant to adapt various cranks to the BB30 bottom bracket, not visa versa.

That makes a lot of sense. Thanks
