Planning to get single speed dropouts CNCed
Planning to get single speed dropouts CNCed

Hi DJ dudes,
I'm thinking about getting dropouts CNCed so that I can run single speed with tensioners.
I'm wonder what design is the best? Open ended rear with a puller tensioner, or a closed in elongated slot and/or with a moto style block or a threaded internal thread bolt type tensioner.

Any advise pics would be great. Also if there are other thread I should ask please let me know.

regards
Ant
If someone can’t custom make them for you just put the chain tensioner upfront and it should work.

honestly, it would probably just be cheaper for you to find the correct dropouts or even buy a new frame. most CNC shops want their orders in bulk. setup time and costs for one measly set of drops are not worth it (unless you have your own CNC).

some shops will do small work like this as they are better setup to do so. although, they will pass the setup/time costs onto you.

with that being said. a regular horizontal dropout with a puller chain tensioner will always be cheaper as its much easier to produce. the elongated slot design with a sliding axle in the middle will be more expensive as its more complex to produce. i can pretty much guarantee you that design will be more than the frame's worth.

finally. call whoever makes your frame and see if you can get whatever dropouts you are after. they may have spares or be able to point you in the right direction.

he might not have a 9mm QR axle to go with the frame. i dont blame him, its the worst axle for dj/street. there should have never been an option from the start.

10mm goes with it too

Or bolt on

Thanks everyone. I do have the 10mm bolt through. It does seem like alot of work getting new dropouts made. A front tensioner looks like the go should one be required.

Thanks again PB DJ crew.

Surly Singleator for the rear would work good too.

Yeah it would work...if I have to use one I will. I'm hoping to have the rear as neat and minimal as possible.

What pedals are people running on their DJ bikes and why?

I just bought a pair of Crankbrothers stamp 1 (plastic) size small pedals for my light trail/XC bike and am wondering what I should I consider for my DJ bike. Should I look at "BMX" style pedals (typically thicker profile and plastic molded pins)?

That Rocky Mountain Flow looks amazing btw. What year is the frame?

I ran a pair of Nukeproof nylons for a while, metal pins.. absolutely loved them.. nice and light, easy to change pins, cheap $30?, and plenty of grip.

I need to buy some new pedals myself and will probably go back to them
