My experience was less successful. A fellow hubber contacted me about a stolen Giant, and confirmed it as mine. Long story short, the bike was at a cash converters. I went to the station at 7:30 about, and started retelling my story (I have an open case) and trying to get them to do something. The SAPS went with me, after a huge fuss and a long wait, to go look at the bike. This was about 8:45. I was told that I may not contact anyone in any way during our visit. The officer then told me that I should be prepared to buy back the bike if I wanted it back... Arriving at cash converters, (10:15) the officers proceeded to haggle the price of a tv set and couch. After getting them back on topic, the cash converters denied having such a bike, even though I had photographic evidence. The police declared all evidence I gave them as forged or false, and continued to shop around. After 30 minutes they proceeded to go pick up their brother who was 20 minutes away. We waited for his brother for about a to hours. The long drive back got me back at the station at 2:45 and absolutely no results.

not a lot of info around, but I do believe it is possible. Maybe go to a bike shop and ask if you can fit a 650b wheel to check clearance? http://www.themountainbikelife.com/2013/05/650b-part-2-build.html

Many say that they ride alone 99% of the time. The thing is, good rat poison is about 99% excellent rat food, and 1% poison. The point I'm trying to convey is that if and when you are riding alone, don't be tamed by the plentiful times nothing has went wrong. always take extra precautions when riding alone. No loved one wished you to get hurt, so don't raise the possibility of doing so and take every precaution you have. Like many of you do, a traceable sporting service like endomondo is a must, and so is an extensive repair kit for both you and the bike. This along side with someone who knows your planned route and most likely whereabouts. Stay safe (well that was my 2c worth)

Sorry, forgot to click reply. See above comment^ Scammer not on BikeHub, but was contacted through it. My own fault.

Sorry, I thought I would get notifications if comments were left. It was that shady Jacob fellow. Sadly I only read about him after the incident. Very foolish of me. A typical EFT with a falsified proof of payment and the " I'll send someone to pick it up "

Thanks! Silverbacks design is slightly different, as it places two bearings on top of each other, after you have placed the bottom bracket in. mine uses the BB as a pivot. I'm still in design stages, so no sourcing yet. But I plan on using common press fit bottom brackets.

So I've decided I'm finished with the concentric BB and pivot thing, sort of, and have moved on to the VPP and DW-link designs. So here comes my first design in that area. Again with more or less the same style and geometry as the previous versions, but not a concentric design. The design has two rockers, one around the BB and one on the down tube. This has a maximum chain growth of just under 19mm. I quite like this design for its wheel arch as it goes through its travel, and I've placed the shock so to use shorts linkages and not to put forces perpendicular to a tube. Also the shock is placed on the down tube, which is a larger stronger tube. Here is the frame before compession And here is the frame after compression

Secondly, the arch at which the rear wheel moves is not ideal for bumps. A wider arch and one higher up will have a better curvature for both small bump sensitivity as well as resisting to bottom out. Opinions?

I've been reading a lot about the anti-squatting designs, and reviewing the arch at which the wheel moves throughout the travel, and have realized that my concentric BB and pivot design has many flaws. Many designs compromise on the chain growth, which causes pedal feedback and reduces power, to stop or minimalise squatting. But where as, according to what I have read, squatting and bobbing from acceleration also decreases power. And obviously is annoying. So I'd like to know your opinions about this. Compromising on squatting for an isolated drive train system, or compromise on pedal feedback to stop squatting?

Sure! I have no problem doing so, if its fine with JKK

Thanks!! I will do so!

Thanks! When I have gained the know how. I'm still VERY new to this whole CAD amazingness. That's definitely the way to go! But rather send enemies than friends... and forget the gum gaurds... Lure them in with the hope of receiving a new bike

Good Morning Having finished the Generation Three design, the time has come to post it on this here thread. So, addressing the issues I had with my Gen2 model I gave the geometry a final good hard scrub. This all is drawn around a 650b build with 140 at the rear and 160 at the front, but it is designed for 26ers and 29ers, with the 29er limiting your travel to 115 at the rear and 140 up front. As I have said this is drawn around 650b, and I am yet to toy around with the 29er specs, but that is soon to come. So starting the same way as the others, I drew up a sketch, getting a handle on the geometry and placement of things. I slackened the head tube by 0.25deg, and lengthened the chain stays by 15mm. Reach, stack and all the others remained the same, more or less. With the shaping of the tubing I really just played around to get to know the program. Again I have no beef with straight tubes, this is just me having fun. I decided to incorporate the use of two rockers, to give the shock a nice progressive movement. Meaning, theoretically, it'll be gracious on the small bumps but also resist bottoming out. Having seen the movement of the shock, I noted that the top rockers angle is a tad bit too close to parallel with the shock, but I fixed that with minor adjustments of 3mm to both the length of the rocker as well as the seat stay. I know no system is perfect, and compensation has to be made somewhere. Mine is on squatting. Having my head buried in that link a fellow hubber sent me containing loads of information concerning squatting and anti-squat, I saw that the anti-squatting design not only sacrifices a little of its small bump compliance, but also pedal power is absorbed through the suspension then. In both cases it is a little, I agree, but their design favors anti-squatting and mine favors an isolated drive train and small bump compliance. But everyone has a preference, that's why there are LOADS of other designs out there to pick from! I quite like my Generation Three design, and will continue to make improvements on it, fiddling to see if I can fit 29ers perfectly with maybe the help of different dropouts and limiting rear travel via mounting a smaller shock, e.g. 184x44 or 165x38 and fitting different rockers to house the smaller shock. I am having Great fun designing these frames, and I'd like to thank all who follow this thread and deliver commentaries on my design, and giving excellent and valuable information. Oh, and to whom it was a concern, you can now have a water bottle on your frame.

No background whatsoever. I downloaded the student version of inventor pro, which is free, and started with the learning curve of the program itself. Then followed research, and so I started. Any place I would deem as a good place to start. Its strange to get going at first, but once you into it, there's no stopping. Edit: spelling

That was my previous thought for placing the shock in Gen3, but decided against it. I like what it says , but I prefer my simplicity of the 2 BB's. I would very much like to test my Gen3 design for squatting, and how bad it will be. But I'd like to test it on the trails, not a simulation. That doesn't mean the squatting won't be calculated though, it is a viable point.
