Thanks for the leads, my kit, bike and pieces and parts are all in route. I am going to likely stay one speed, even though I have a 3spd drum brake SA to use. To flat here to bother. 30t x 22tWoodlandHills wrote:Really, do as Karl @ electric-Fatbike.com suggests and run a 3-speed IGH. The sprockets are steel, you can shift at a stop or while standing and coasting and they can be dead silent. In first gear the loudest sound is the crunching of the tires on the stones on the trail......
I had to make a custom 34t rear cog, but now you can pair a 26t Surmey-Archer cog with a Luna 30t chainwheel and climb any hill around. Use the rear dérailleur as a chain guide/tensioner and you will never have a thrown chain either.
Hard on the wimpy 10spd chain?, is it worn out already? How many miles? What wattage? Maybe you should look into a new deraillerur.sather wrote:I agree. A one to one ratio is the way to go on the BBSHD with the Luna 42.
I am having issues with the Wolftooth 42, SRAM 11/36 cassette with Shimano Deore Xt long cage. I get the thing to work perfectly on a stand, ride it for a few days and it stops indexing. This is very hard on a wimpy 10 speed chain. I have had to repeatedly adjust the stupid thing.
BTW: Wolftooth does not recommend using even a 9 speed chain, only ten speed.

I am not really sure how or why this happened. Under some climbing loads but not by any means super steep climbing the chain broke. I had some spare links in my repair kit so added a few links and I was OK to ride home but to my surprise when I was putting the repaired chain back onto the rear cassette I noticed the wonky ring. Both the bent cog and the broken chain must have happened at the same instant. I have straightened the cog out now with some time tweeking it in a vise but my guess is now that it has been once bent so badly it weaker in strength than it was. Looking closely at this cog it has nicely made but more consideration for weight than strength. I will ride it as is for now and hope for the best. Maybe for its 1,000 mile birthday I will spring for one of the Luna Might Min 30 tooth rings and a Sturmey 3 speed IGH.
