Oh okay. Everyone seems to rate profiles differently :l some people say that they love them and some say they completely blow, it's also not related to their ability at all. 48 engagements on the back is supposed to be equivalent to 72 mounted on the cranks (on a mod) Also I've never found the extra weight on the back to bother my riding

Yeah fair points. Do you not like me or something?

Really? the only benefit I can see to a FFW setup is weight, and it ain't enough to warrant it.

if you're making a metal piston make have 2 O rings on it and use GREASE

If spit takes too long use disk brake cleaner.

I stll think you shouldn't of got it bodge welded by some engineer because of such a small crack.

That could sound interesting but what os the estimated time to make one? I also have to make a large write up for next year so can't spend all my time in the workshop I have my maladie with a snapped Chainstay and lots of hammer dents that I'd like it to match f that helps

There will be constructions to hold things in the correct place, but not to the precision of exact geometry.

That blurred lines in public video is SOOO cringey. In other news, Trialsbikingnunn showed me this:

Gap to the chain was really cool man Great style too

You really shouldn't of got it welded. you would of been much better off simply drilling the crack

The George Blake Tonk Series frame will be a one off mod frame

Excellent, thank you for that I am making a seatless frame indeed. I may go for several seat tubes like the 04 zoo pythons have.

Hopes are more "crisp" in terms of engagements, and I would much rather have the more solid engagement of one over a king on a street bike. Sound mint as well, and you can mount a disk easy peasy

Well, this thread was going to be started by me sooner or later, so it might as well be sooner. It is coming up to the second year of my BTEC Engineering level 3 diploma, and as part of the second year you have a main project where you make anything of your choice. Of course being the avid trials rider I am, I have decided to take on the challenge of making a steel trials bike frame. We have all the equipment available at college and I believe I am passionate enough to finish the job, which is why I have taken it up. However, I also know that if I do this without the help of the forum, I will regret and do it wrong, so I am asking for your help even in the designing process. Due to the lack of a jig the geo is not going to be completely spot on, so I am going to simply aim for short CS, high bb and long WB. with a 116 rear end and 4 bolt mounts. I am making this to ask for help on dimensions for tubing, I am going to need the following tubes: 2 x tubes for CS 2 x tubes for SS 1x tube for BB shell 1 x tube for Headtube 1x for the Top tube 1 x for the downtube 1 x for the seatstay I am going to ask for much longer tubes than I require, for example 600mm tubes for the CS just so I have room to cut them down to the specific length. I am going to go for tubes with a material thickness of 0.8mm thick all round, as I think this will make a good weight/strength compromise. However one think I am stuck on, is the outer diameter of the tubes. I could measure my frame but because that is Alu I would not get the results I need for steel tubing. Can I have some assistance on what I require for CS, SS, Top tube, Down tube and Seat tube, someone who is familiar with working with steel/frame development would be most helpful, but anyone who thinks that they can help are more than welcome to join in with the conversation. Please, feel free to comment on this thread with views, opinions, critisims or praise, everything will be read and considered. I hope everyone looks forward to the next year as much as I am and enjoys looking at the progress of this project. Thank you George xx

If you're unsure just ask flipp and he'll call you an idiot so you know for sure you're wrong

Hope are more reliable for street trials especially.

The seat will be higher into your buttocks.

Are you trying to fit a barb?

Still get a hard on looking at this

Spit and pull

Pardon?

Okay
