3d printed friction shifters


#1

This is just a poll to gauge interest. Would anyone put 3d printed friction shifters on their bike?

Pic for ref. This is an indexed shifter prototype – A friction-only version would be more compact.

Mech would be a functional clone of the Simplex retrofriction one-way clutch, a.k.a. the best friction lever experience bar none – but every internal part is straight out of McMaster-Carr.

“Angled barcon” would be a bar end shifter with the mech / level angled 25 degrees or so from the bar clamp, the better to work with townie bars.

Each style should be individually customizable for

  • amount of cable pull (should work fine with 11sp systems)
  • handlebar / downtube clamp diameter
  • color of lever and body (within Shapeways color options)

Pricing TBD but should be less than what a pair of Simplex SLJ with worn out bushings lists for on ebay

  • Yes, Thumbies
  • Yes, Barcons
  • Yes, Angled Barcons
  • Yes, Downtubes
  • Tickybox

DQ: are these metal or plastic?


#4

They’re plastic (Nylon). I’ve been finding it quite durable, has flexed away from some hits that would have wrecked suntour bar ends.


#5

These look really cool, wish I had a bike to put them on. Would do the Trek 720 commuter but probably selling soon


#6

This


#7

v interested in thumbie possibilities
have you tested the thumbie printing?


#8

would be down to put these on my trek 720, or maybe a thumbie for tandem drag brake


#9

What are some of y’alls favorite thumbies?


#10

I’d buy some thumbies to replace the super stiff “silver” thumbie on my P/R.


#11

Just wanted to say that this is a cool project but I haven’t voted because I don’t have a clear use for any of the above options


#12

my only experience with friction thumbies was some falcons on an 8sp and they were junk


#13

suntour:


#14

Good ol’ Shimano M700


#15

Cool. Ive been wishing for pink dt levers and maybe it can come true.


#16

I’m fond of last-generation Suntour like http://www.bikerecyclery.com/suntour-xc-pro-thumb-shifters-7-8-speed-index-or-friction/

I have a rear one of those paired with a Campy front on my townie, but I’d happily replace them with any design of yours! I’m also into a pair of downtubes for my ALAN, the vintage Simplex are kinda clapped out.

I’m sure we could use some barcons at Backalley for Crust builds (friction 1x12 Eagle!)


#17

I had those Suntours BITD and they were head and shoulders above my Shimano thumbies at around the same time. I called the Shimanos palm-shifters.


#18

one proto sent to the printers (in orange tho)


#19

Are you going to have them printed in plastic or a combination of metal and plastic?


#20

Planning to have an all-plastic version but metal bits could be an upsell.
