I was wondering that!!

How does it lock?  ???

Does it need a padlock?  :LolLolLolLol:

stops the rear wheel from going out of line and keeps chain tension etc

nice snug fit will keep everything nicely tucked away.

How does it work? Is there an adjuster or something that isnt shown?



Thought I'd seen something, similar type of idea?
http://www.winstanleysbmx.com/product/16018/Simple_Wheel_Slammer

The wheel slammers have the extra material on the washer sandwitched between the axle and the front of the dropout, those pics show it at the back?

i think once they are fitted nothing can move out of line ,i think thats the answer  if they are held in the grove it cant twist.
Title: Re: new lock drop out proto
Post by: dibly on March 13, 2009, 02:09 PM
Aren't they already available?

Bru  :daumenhoch:

thats right dude, along similar lines mate  :daumenhoch:

So it cant twist, but it can still move forward. So what is keepin the chain tension?



thats right dude, along similar lines mate  :daumenhoch:

The slammer things jam into the gap between the axle and the end of the drop out slot (they sell them in a range of thicknesses. Where is the similarity to your one?
Title: Re: new lock drop out proto
Post by: SaMAlex on March 13, 2009, 02:22 PM
It's the same but in reverse, if I understand the pics correctly, but I'm having a bad day so I could be seeing owt  :crazy2:


So what is stopping the wheel from moving forward? (ie, keeping the chain tension)  :-\
Title: Re: new lock drop out proto
Post by: SaMAlex on March 13, 2009, 02:28 PM
The washer bit hooks into the rear dropout by the looks of it to me, stopping the wheel traveling forwards,


Im not getting it, sorry.  :-[
The washer can still just move forward with the wheel.  :-\

its ok alex, i never said they were the same as the simple just along the same lines not that they work the same, il take some more pics when im back in my work shop, just packing to go to taiwan for 8 days, i took the picture with the the spacer in the wrong way

I get it now!!  Its a fixed width chain tensioner!

But what happens when your chain stretches a bit (before it eventually snaps)!!

Its not exactly adjustable.  And if you change your Sprockets then you'd need different widths to get your tension sorted again!!

I'd like a drop out tensioner that is adjustable but allows you to line up your wheel in both directions.   My Auburn Aluminium Rear end likes to increase the tension when tightened.  It makes it hard to line up properly with the right tension.

yeah but moley iv never seen you do flairs and stuff that would nock your rear wheel out of line  :LolLolLolLol:

il take some more pics when im back in my work shop,

Cool. I look forward to them.
Its about time back wheels stopped slipping forward ..... but I wont hold my breath for this one  :LolLolLolLol:

Thats why the Simple ones are avalable in diffrent thicknesses (fractions of mm's). You get the one you need for your sprocket size

im not asking any one to like it, it may not even work as i said in my first post, just trying it if its crap its crap you just dont know unitl you try

I just wanted to know what it did and how it worked.
I LOVE bike design and its not obvious from the pictures.

sorry alex i wrote that thread before i saw your last one mate no offence intended dude  :daumenhoch:

Post by: moley on March 13, 2009, 02:46 PM
I've worn flares, does that count!!  :D

I like the idea!!

Chain tugs are a pain in the arse!!

The biggest problem I have with them is that they don't stop the tension being tightened when you tighten the nuts.

You think you've got the right tension.  You tighten the nuts and oh shit its way too tight coz the fecking wheel has shifted.  :(

Great Idea Dibly and allows you to keep the wheel straight!!

Dibly get yourself to Coppull on the 29th for the 1st Round of the Summer Series!!  :daumenhoch:

Ive worked out how these dropouts work. Its nothing like the simple slammers.

Youd think the person who "invented" them would know how they work ......  :-X
Title: Re: new lock drop out proto
Post by: bsdforever on March 16, 2009, 07:52 PM
I saw a dropout just like this when I was in taiwan two weeks ago

alex come on i said they were along the same lines as the simple slammers ie stop the wheel from moving

its ok alex, i never said they were the same as the simple just along the same lines,  i took the picture with the the spacer in the wrong way

The washer in the picture is in the correct way round. The tag at the back isnt to wedge the wheel (like simple slammers) its to make sure the washer doesnt spin round, cos it will only work in one direction.



Who invented them Alex ?

I dont know who came up with the idea, but it doesnt sound like it was Dibly  ;D

OK, My bad. I miss read what he said at the start. I thought it was an idea that UK bikes were trying out  :-\

if you look real closely at the pic you can see how they work.

it has to be really close tho. 8) seems like a decent idea i think.

Yeah, I loved the idea at first but I aint so sure now. I think the non drive side might slip backwards real easy. Like throw your wheel out of line if you hit the wheel sideways. It'd be good to see how the proto types work out.
Title: Re: new lock drop out proto
Post by: teamsano on March 23, 2009, 05:30 PM
i've only ever used a chain tensioner on the one side, and never had probs. you can get a real good torque on 14mm axles.
Title: Re: new lock drop out proto
Post by: lodge on April 01, 2009, 10:59 AM

I agree, sorry but i find it hard to believe that people have problems with wheels moving when using 14mm axles with the nuts tight, I'm sure my rim would fold before the axle ever moved in the dropouts.

Post by: Stodgy on April 01, 2009, 11:15 AM
LOL - ask Pete quad about moving fooking axles...bastard almost killed me.

Somebody send him a torque wrench!

I like the Simple washer idea, a fine example in lateral thinking. I'll be using them in the future. I've also always wondered why companies haven't developed a smaller tidier version of the snail cam adjuster. It pushes instead of pulls, there are no nuts or bolts involved and all the frame needs is a small roll pin or similar in front of the dropout slot for the snail to locate on. It allows adjustability and prevents the wheel from slipping forward, without having owt hanging out the back of the dropout.

Post by: SaMAlex on April 01, 2009, 01:28 PM
Hey Rob, are you back now? If so, good to have you again.

Have you worked out how this one works yet? Its all in the photo but its not that clear at first
Title: Re: new lock drop out proto
Post by: TwoBobRob on April 01, 2009, 01:35 PM
Hey buddy - yeah, I'm back.

I've not really looked at the orginal post to be honest, I kinda skipped through the comments and because poor old Dibbers got on the defensive so quick I've not bothered....

I'll go and look now   :)
