Hey guys, I just ordered a Python Yao Zhi frame from Tartybikes  (Y)  (Y)  Thanks so much for helping me out Dave! :-  :blink:

However, the components I am using are basically T-Pro 2003 standard parts, I have no bashring :blink:  and will develop UCI riding very strictly for a while. Now, my main concern is Chain tensioning, I had to use DMR chain tugs on my T-Pro 2003 which does not have snail cam capabilities as the 2004 T-Pro.

So, I just looked at close up pictures of the Python frame on Zoobike.com and tartybikes.co.uk and ashhumphrey.co.uk(nice one mate!), and I think it could be possible to run tugs on the OUTSIDE of the dropouts (as inside of dropouts is bad and stretches frame etc.) by filing my chain tensioners to bugger :o

Now, if I must resort to snail cams, then just a few questions: will it be wiser to run the snail cams on the outside or inside of the Python YZ frame?

Or will it be possible to run without any tensioners for a bit, I have a Tryall fixed mod hub so it's an allen key bolt setup, but could someone tell me if allen bolts on their own are going to hold the wheel tight in place without the wheel bonking around?

Sorry about this long winded post guys, but, anyone up for a ride in London on the Last april Sunday? I believe that is the 30th if I am correct.

Im using chain tugs on the outside of the drop-outs :blink:

works fine...im using the standard onza uns :blink: just that theyve been cut down in a few places.

Snail cams are the best. (Y)"

They hold your wheel better than any other as they are infornt of the axel, not behind, and they are so much simpler.

You can't run a mod wheel without any sort of chain tuggs, as it will constantly move.

Snail cams! I have only one on the driveside and my wheel has never moved even when I am whacking down some serious power through the cranks.

Snail cams all the way :)

Where did you get that theory from :) .

Well, if you have allen key bolts, you can't exactly get them realy tight like you can with standard bolts. My wheel moves about with them, not to mention without.

[JonMack]

My chain tugs on my BMX have nuts on them. I would have thought you could get allen bolts just as tight as nuts anyway. Its not exactly a hard concept, the twisting of a tool in a clockwise motion until you cant twist it anymore.

Yeah but with those bmx type nuts you get a spanner wrapped round them, and you can pulse your weight onto them to get them realy tight. But with allen key bolts you cant get the leverage, as they are generaly shorter, and the allen key dons't go in very deep, therefor if you put forse behind them the allen key flys out and the bolts get rounded off. :)

[JonMack]

But that doesnt matter too much. I find if i come up short on a gap then the wheel would get pushed forwards towards the seat tube, the chain tugs stop this from happening as they are pulling backwards on the wheel. If you dropped the bike onto the back wheel from holding it vertical, then it gets pushed towards the seat tube again, the chair tugs stop this. The chain tugs allow the chain to be set kind of tight, so the wheel cant fall out the bike backwards because the chain is pulling it towards the seat tube, again. The only way I can see them "failing" is if you have them completely undone, you come short on a gap, the wheel gets pushed forwards, and the chain slips off, the wheel then bounces back and out of the dropout, but still, the tyre wouldnt fit through the brakes, so it can't fall out.

So saying

You can't run a mod wheel without any sort of chain tuggs, as it will constantly move.

is a lie.

I don't really get how you mean the wheel would get pushed forwards gapping? Surely it'd get pushed back as you hung the back end up?

Aaaaaaaaaaaaanyway, it IS possible to run a mod without chain tugs, but it's a bitch fine-tuning it, which is where our lovely friend Mr. Tug comes into it. On my T-Pro, I'm running some random-ass chaintug on the right, with the sticking out part of the bolt cut down so there's just a tiny bit showing past the nut. It keeps it all low profile, and because of my constant gearing and chain length (KMC Kool, so minimal stretch, and it's worn in now anyway), I don't need to alter it to take in more slack anyway. But yeah, me and every BMXer (mostly) in the world have generally found chain tugs to work perfectly well, but it seems that now frames are coming with just the option to run snail cams, which seems a little whack...

I think with the Python, your best bet will just have to be snails outside the drop-outs.

Gutted :)

Oh shush you :)

I dont know how it happened but a few times while i was on my BMX my wheel got pushed forwards when jumping shit, leading to lose chain syndrome.

You sure that wasn't you landing at an angle, thus pushing the left side of the axle back and the right side forwards, meaning slack chain?

[Sikamon]

and because of my constant gearing and chain length (KMC Kool, so minimal stretch, and it's worn in now anyway), I don't need to alter it to take in more slack anyway.

whats weather like sunday we riding or u busy?

err... you have said several times in there that chain tugs stop the wheel from moving, so surely he is right in saying that if you dont use tugs the wheel will move?! :)"

That confused the hell out of me. It seems to be making my point more valid. :) :)

All i'm saying is that just having bolts has little forwards and backwards hold, its metal on metal and can/will slip, the tuggs stop this. I have run my bike with the tuggs realy slack, did a few drops and they were tight, therefor the wheel must have moved.
