Interesting discussions on fork stanchion sizes. Pinkbike posted their latest huck to flat video of 5 trail bikes and 5 enduro bikes, and the forks have stanchions from 34 mm to 38 mm diameters. The same rider rode all the bikes off the same jump and the slow motion camera had the same view...
I have been running the ethirteen Helix R for a while now and have some additional comments:
- Shifts to larger cogs are similar in feel to the GX cassette
- Shifts to smaller cogs can be a bit clunky
- To get the best shifts to smaller cogs you have to adjust the derailleur to be a bit more...
It works great. The chain does not rub on the chainstay protector and you won’t need a larger chainring. Shift quality is the same as with the GX cassette I ran previously.
