Bike projects - a how to

Equipment

I’ve not contacted the seller and have no plans to. It’s annoying but I don’t think there was deliberate deception.

Consensus from the research I’ve done suggests one of 3 options:

  1. Simply change the frame, and sell the Emonda, with the caveat that the frame will only take a Shimano bb/a bb with OS bearings.
  2. Strip the whole thing down, sell everything, and start again.
  3. Put on a sub compact Tiagra (48/34) with an OS Shimano BB and see if that works.

3 would be the cheapest, but would look pretty fugly…

63

Why does it have to be a sub-compact? If the chainring bolts are the problem, wouldn’t you need to find something with a different bcd? Or can you go 1x with a direct mount chainring?

64

The idea of sub-compact would be to maintain the original gear ratios (or close to).

I imagine a wider bcd might solve the problem, but there is apparently less clearance on SRAM chainsets than Shimano.

1x is an option, actually - good shout. Though I might want to change the cassette to a 10-36 if I do that.

65

I’d be on the phone to SRAM and Trek stat!

It’s a bit BS for you! They must have a solution. Just tell them the bike is on it’s way to another Hambini video Review.

66

That had crossed my mind, though as a 2nd hand frameset, I’m not sure I’d get far.

67

It’s free to try. I’ve recently got a warranty fork from Giant after I snapped a brake caliper bolt in it. I even said it was 100% my fault.

68

You’re quite right. Worst case scenario is they say go away.

69

You really should. From some quick Googling I’m pretty sure Trek sold the last gen Emonda with Force eTap AXS stock. I cant imagine they sent them out the door with chainring bolts hitting the frame.

70

Yeah I’ve done some digging here as well. Even if they didn’t sell it with AXS as stock, it was available as a frameset only, and nowhere on the website are any incompatibilities stated.

My problem, though, is I’m not the original owner, so I’m essentially dependent on Trek’s goodwill here.

I have contacted the eBay seller, pointed out the problem and asked for details of original purchase in the faint hope it might help.

71

Quite probably that guy was running a Shimano drivetrain and hasn’t had problems. I really find it unlikely that this person would even think in this direction.

I’d get in touch with Trek and see if they can accommodate you. Or you have to sell that frame. Sorry to hear, your build seemed to have gone flawlessly and quickly from inception to finished bike.

This :point_up:

Also your other half’s tweezers are great for internally routed frames and getting flint out of your tyres!

73

Is there enough play to shim the drive side end of the crank spindle by 0.5-1mm? Maybe a slight bodge, but would probably stop the rubbing. Shouldn’t be an issue for the front derailleur either, but you’d want to set up its adjustment again.
