My post was to let everyone know about my experience... maybe DON'T BUY was a bit harsh but no one from the club I ride with has seen such a catastrophic drivetrain problem happen before outside of a crash. I took the frame to a carbon repair shop and they said that they have seen this problem with speed concepts before. They offered to repaired the frame for $2800 as they need to fabricate a custom mould for the rear triangle to bond in a new dropout.

paul thomas is on this forum board. he's hooked up with a carbon bike repair outfit down in tucson where he lives, and i'll bet can repair your bike for a fraction of that cost.

You might be able to get Trek to replace the frame under crash replacement for less than that. Now if you bought the bike 2nd hand I am not sure if that will work. Also, if you bought the bike 2nd hand then maybe there was some unknown damage to that area when you bought it.

Were you able to get the stem seating issue resolved? Just got an SC from dealer and the space below the stem seems comparable. Obviously dealer should be answering these questions but their head guy is the one that built it up. Took a look myself and seemed the stem attachment bolts fully tightened don’t allow the stem to get any lower.

I don't advise this at all - but I have worked on a few stubborn SCG2 that would not seat, as I said I do not advise this but what I did was;

  • Remove the pinch bolt completely from the stem
  • Run the stem bolts in slightly
  • Stick a flat head screwdriver where the pinch bolt was and open up it up
  • hit the stem down-word with a rubber mallet
  • screw stem/pinch bolt to spec

Like I said - just what I have done and something they would most likely never recommend or do from Trek HQ or Trek LBS

^ method of last resort :)

I found that disassembling back to scratch (steerer removed) and rebuilding, checking for alignment at each stage worked. When assembling have the frame rest on its side so there are no loads up/down/fore/aft. Seat the stem before inserting bolts. Tighten carefully and keep checking.

This was a labour of love so I may have resolved the issue and not noticed as I continued on. It never harms to be thorough.

Trek still has a few of the 2017 gray frame sets at a closeout MSRP of $2500.

A brand new one is $4000. You may find some dealers with NOS willing to let a new bike go for $3000.

Instead of repairing, I would go new.

Just replying to the last post. This also probably needs to go in the "Cry like a biatch" thread but here goes.

I've got a 2nd hand SC and recently wanted to lower my pads and bars to be a bit more aero.

I've got what I assume is the standard Botranger aero bar and so ordered a set of various size bolts so that I could remove some spacers and lower myself.

WHAT KIND OF COMPANY SELLS THE BOLTS IN 2s WHEN IT IS BLINDINGLY OBVIOUS THAT THE MINIMUM YOU WOULD REQUIRE TO HAVE YOUR PADS/BARS THE SAME HEIGHT ON EACH SIZE IS 2*2=4?!?

Rant over. Just seems ridiculous.

I should add, I didn't buy them from Botranger or Trek but an online bike shop which I can't remember the name of. They were pretty hard to find I thought.

Just wanted to vent.

I was able to get the word from Trek tech. The shim between the stem and fork is the cause of the gap. They started including the shim to prevent the stem from damaging paint from contact. Sounds like their wholesale use of the shim is pretty new. But it is safe to ride with or without it, whichever you prefer.

I do! Gen 2 7.0, so no aero base bar. I actually snapped one of the bolts that hold the base bar on recently (under heavy load while climbing), which is when the creaking started to get worse. Shop replaced the snapped bolt, but the creak stayed for some reason.

The only time I really notice mine is when I'm on the base bar and applying lateral pressure. Not so much when aero. Seems like it's just an annoyance at this point, but I do plan on bringing it back into the shop relatively soon.

Ironically, this is the exact reason why I came to the forum today, glad I'm not the only one with the issue :).

Warning to all. DO NOT buy a speed concept. I was riding at 20ish mph when out of nowhere the rear drop out snapped. the derailleur then spun around breaking the chainstay and seatstay and bent my wheel beyond repair. Somehow I managed to get away with minor injuries, but it could have been catastrophic. I always thought that Trek was a leading manufacturer of bikes but clearly either my bike had a manufacturing flaw or their engineering department needs to put more thought into rider safety!

Hah! Funny you post this.

The same thing happened to me, but it was on a 2.5 (the aluminum frame). It was working perfectly fine when I put the bike of the car. I drove 20 minutes to the trailhead and took my bike off the rack. Low and behold, my RD was hanging by the chain.

I don't know if it's a manufacturing defect or what, but the guys in my local shop couldn't believe it. Fortunately Trek replaced it with the 7 series frame.

I'll be buying another SC because of it.

Thanks for posting. I have a 2018 project one and was concerned about a gap between stem & fork after reading earlier posts. Shouldn't need to worry then. I will mention it next time I'm in LBS anyhow.

Just joining the SC Family! Have a 2015 7.0 on the way from another awesome Slowtwitch member. First thing I am looking to do is replace the race lite cockpit for the Gen 2 cockpit with the mono extension. Anyone looking to sell theirs? I am unable to post in the classifieds section yet.
