Hi Carl, thanks for this.
Does Trek actually sell these little pieces and Can this part be ordered through the Trek Bike LBS store? I would just like to get a bag of say 30 pieces, I know that each little nylon trim clip or grommet probably only costs about $0.02 but I would like just a few spares. Alternatively, are you able to indicated who makes them so I can just buy them locally?
Thanks
Sean

Any Trek dealer can order that part# for you in whatever quantity you want.

I just bought a 2014 9.9 frame set (haven't received it yet). Can anyone tell me which set of bearings for a Rotor 3D crankset?

Thanks

Re: Official Speed Concept Owners Thread [bonafide505] [In reply to] Quote | Reply

First of all, make sure you've got a 3D and not a 3D+ (aka 3D-plus)...the latter is not compatible with any SC.

Rotor says the 3D cranks are Shimano compatible, so these are the BB90 kits your Trek dealer can order for you:

411813 ceramic
404699 steel

and you can now get CeramicSpeed BB90 kits from your Trek dealer as well...the Shimano versions available are:

518150 standard
518152 coated

Thanks Carl!

I have a similiar creaking noise on a 2012. Been in a couple LBS - bottom bracket torn down but no solutions. Did you figure it out?

sorry why can't you simply use a bb90 to 30mm adapter to fit the Rotor 3d+ or rotor power?

The bearing size required to get a 30mm spindle into the BB90 cups is so small as to raise serious concern over durability...never mind drag. Have yet to hear of a long-term successful installation of a system like that, and have yet to see the results of lab testing to support same. Not saying there aren't solutions being sold out there...saying we can't vouch for their effectiveness so we can't recommend them.

Thank you very much Carl. Never thought bout the bearing size issue. I know of a friend team here in Italy that uses Canyon Spedmax (BB90+Rotor power) with no apparent issues, but i reckon that the kind of issue you are suggesting are more on a long term and/or on a professional drag and reliability standards. Thank you again,

Carl, is it possible to just get the plastic stem cover for a 2014 long far stem? I, well my kids, stepped on my cover and obliterated it.
I don't see the separate part number.

Hey Carl,

Tried to search but can't find: early marketing materials claim the 2014 speed box 2 can fit two gel flasks. I can't to find one that fits--do you know what brand(s) were tested? Also, ever seen anyone mount a water bottle directly on the TT / is that a horrible aero idea?

Trying to find a way to keep concentrated infinit and a BTA bottle of water up front.

Love the SC, fits amazing and its flat out fast. Huge fan of my 7.5, thanks.

Hey adamas-

Glad to hear you like the bike!

On the gel flask, try this?

As for toptube bottle mounting, you'll probably find a regular bottle interferes with your knees. I've tried mounting an aero bottle there and I found the additional height compared to a flask holder or speedbox was annoying for the same reason...but I may swing my knees in a little tighter at the top of the stroke than others, too. If you're going to try it I'd suggest starting with a smaller aero bottle like the Elite.

Speed Wobble
Have you experienced speed wobble on late model carbon bikes? Or earlier styles of bikes (tubular steel, aluminum, tubular carbon)?
Yes
No, but yes on older, tubular bikes
No, and never on prior kinds of bikes
No, and I've never had other bike styles
I don't have a carbon monocoque bike
What's speed wobble?
