Wtb/bar end shifter question

[mike gasparino]

Hey guys,


I have a 1x10 set up on my Atlantis with a 10 speed xt cassette and derailleur. I need a rear bar end shifter that can go up to 10 on friction, which I'm pretty sure most Shifters can do if I'm not mistaken? thanks!

Most friction shifters should have enough range.  Stay away from Shimano BS79 bar ends, they're 10 speed but have no friction option.  BS78 bar ends offer both 10 indexed and friction.

microshift has a bar end that can do 10 speed xt dynasys index, but also can be put into friction mode. has more cable pull than a regular shimano bar end i think, so youre 10 speed friction will be a bit more precise.

[Jon BALER]

Shimano 10 speed mountain/dynasys needs more cable pull than traditional friction shifters, so you can't use just any shifter.

Microshift is the only compatible bar end shifter that i know of. There are other options for friction shifting for downtube or thumb shifting that will work with dynasys.

There is also a modification that I have used to make a 9 speed shifter work. Take a dremel to the shifter and increase the lever travel.

I inadvertently proved today that Silver shifters can shift 10 speeds, if not mountain or Dynasys (I know nothing about those). I replaced the Bontrager 44/40/26 triple with a Logic on a offset 130 Phil, with 42/28 rings, so I had to change my cassette. For me, this means dumping the cog box onto the floor and scrambling around to find the right sizes -- the collection includes Uniglides, 7s, 8s, 9s, and apparently even some 10s. I found the butt end of a cassette, 3 cogs riveted together on a spider, 21-23-27, which looked just right for the big end, so I put that on. I wasn't paying attention, so I just shoved the other cogs on with 9 speed spacers, and was a bit disconcerted to find (a) that the lockring had to be pushed hard to engage the threads, and (b) that I had to adjust the inner limit screw. The 9 speed SRAM chain shifted fine.

Then I looked more closely and found that I had a home-brew 10 speed: 13-27. That would have been very good news, except that my hub seems incompatible with dished big cogs; the inside of the 27 lightly rubbed the spokes. When I substituted a "flat" big, I could no longer squeeze 10 onto the freehub body.

But the Silver BESs shifted the 9 speed chain very nicely across all 10 of the cogs.

Given my experience, I will now simply buy some 10 speed spacers (if I can find a source that doesn't charge $7 to $18 per) and a new chain, and build my own 10 speed cassette. I think that the ~2 mm saved by the narrower spacers will more than make up for the absence of a dished inner cog.

Anyway, an interesting experience -- 10 speeds with 9 speed spacing on a Shimano freehub.

Very cool solution, Patrick. I later read your comment about ordering a 13 first position and a 30/31/32 single big ring. Maybe that is what Steve P did on his franken-cassette. Sounds like an ideal solution for my CX bike w 46/34 up front and lots of hills I have to ride because I live at the top of one of the bigger ones around!
