Trek Crockett - question for owners
For those that own a Trek Crockett, or deal with Treks, I have a question about installing an internal Di2 system on this frame. I do not own one of these at this time but am looking to pick one up and ideally build it out with hydraulics and Di2.
From what I can tell there are two things missing: 1. No hole in the seat tube for a front derailleur wire. I could always make a nice neat little hole for this. 2. I checked out a complete build of a Crockett on a showroom floor. The downtube does not join the bottom bracket in a 'traditional' manner. See internet photo below. The downtube is attached to the BB 75% of the way around with the bottom portion of the down tube left open for the front derailleur cable to come out of. This leads me to speculate that there isn't a hole in the BB shell where the down tube joins it. If the BB does not have a hole where the downtube joins, then there can not be a wire coming from junction box A (from the shifters) to connect to junction box B which would be in the seat tube - for a completely internal Di2 system. Just for clarity...traditionally there are holes in the BB shell for junction of: - Each chainstay - Seat tube - Down tube Does anyone know for a fact that there is or isn't a hole in the BB shell where the downtube joins? Any other things to consider on building a Crockett with internal Di2? It looks like you can run a wire to the rear derailleur through the chainstay drain hole. (see internet photo below - this photo came from a guy that built up an external Di2 system with a single chainring. I am looking to have a front derailleur as well as everything internal). http://redirect.viglink.com/?format=...09%09%09%09%09 http://3.bp.blogspot.com/-Aps2LFtV9N...itled-6987.jpg |

I happen to have a friend's DI2 equiped Crockett that I'm borrowing while they're out of town :D I snapped a few photos of their set-up that I hope help. Let me know if you'd like photos of anything else.

Looks like the crockett easily has room for a 700X45 tire. That is good info for my future builds.

rim I'm pretty sure you could even fit a MTB tire. It's a really versatile frame...it has attachments for fenders as well. Great value. |

I can confirm that a Stages powermeter on an Ultegra crank does not work on the 2016 model Crockett.
Not only does a 10mm hex (used to measure the gap) wrench not fit, the Stages meter its self actually hits the chainstay. Its a no-go. The flip side, as mentioned above, it has a lot of tire clearance. |
Just confirming what has already been said above. The Di2 will most likely need to be partially external, at least for the junction box as there really isn't a place to slide an internal one into the frame.
Also, as for Stages, the standard road models will not work. I ended up picking up a Sram X7 mountain bike Stages and paired that with a Force 1 drive-side crank. The spacing on the X7 gave enough clearance, and I've never noticed any issues as far as having the Q-factor being slightly different on the non-drive side. |
I wish my cassette was that clean.
