I have a 1x12 SRAM setup on my XC bike and I really like it. So, I put my skepticism aside and upgraded to a 1x11 system on my gravel bike.
Here is how I built it:
- Shimano 105 right shifter (11s)
- Wolftooth Tanpan
- Shimano SLX-GS derailleur
- Shimano 11-40 cassette
- Wolftooth PowerTrac Elliptical 40T 110BCD chainring
- Box 11 Speed Chain
I added four (4) links (3+quick link) to the chain after wrapping it around the large cog and chainring. However, the chain angle looks pretty extreme to me. According to Shimano’s site the derailleur can handle up to a 46T chainring w/ a 1x setup. So perhaps I am overthinking things…?
Here are some photos:
Small cog chain angle (please not I am not referring to chain line - how the chain tracks from the chainring to the cassette. Rather I am referring to how straight the chain is coming off of the small cog towards the derailleur’s jockey [upper] pulley).
The derailleur cage angle is pretty far forward (might be easier to see in the top photo)… Is this normal? Am I overthinking things? I just do not want my drivetrain to blowup on the first big hill…
My concern might be a little more heightened because the drivetrain is pretty noisy. All the components are new, so perhaps it just needs to be broken in a bit?
