    Ha. That explains it! Yeah it was the offcuts I'm interested in... skips it is then. Thanks dude. And thanks about the frame! Got it built up: Light! All this chat of the top mount, and it was the bottom one that was the issue About 10 mins of playing about on the car park and a few small rocks / low walls, and I found the above.... arse. Super disappointed. I think the butting must have ended close to the dropout, so the tube there was 0.6-0.7mm thick... But, I decided there were positives, in that I had found it early so would be able to fix it rather than have to fit a new chainstay. In terms of heat treatment / heat affected zone (HAZ), in theory this is reduced as you need to put less heat into the tube for the TIG braze. However, my testing showed there still is a HAZ and that it's not really much (if at all) different to normal TIG welding. One benefit I can imagine though is that the ductility of the silicon bronze filler material is huge - something like 65% elongation to break. Steel is around 20%. So, in theory the fillets are 'stretchier' and could load up the tubing less. In turn this could make the frame feel 'springier' and more compliant. This certainly ties in with how the bike rides - it is so nice! It just floats over those awful eyeball-shaking vibration-inducing micro bumps. There's a descent round here I know well which is pretty smooth but then the last few hundred metres turns into fist-sized rocks. You hit the section at about 20mph and previously it was a real effort to maintain speed and just hang on to the bike - pretty scary to be honest. But last night it kind of floated over. Hard to explain. I guess this is what the 'steel is real' brigade have been on about for years. Here's a badly out-of-focus photo from a quick blast last night. The bike absolutely flies, both up and down Happy bunny!

    Unit move complete. Over the moon to have all my cars back under one roof and with plenty of space to spare too! Second lift is on order and hopefully fitted by next week. One very tired, but relieved Samuel. Between 6 of us (trying our best to keep to the rule of 6 job were all currently landed with) we managed to move everything out inside 4 days. We made an excel inventory of everything I’ve got down to individual parts, totalling 357 (not including part quantities). I’m amazed that it all fit inside the old place!

    Hi guys! My name's Andy and I'm new here. I see for a trials-forum some of you also have an interest in cars - which I do too! I think we might get along. Below is a picture of my track cars, neither of which work, seemingly ever. Even if they did, they'll probably be considerably slower than my company car. Andy P

    Picked this up in December as a replacement for my Audi A6. Feel a bit like an old man in it sometimes!

    It’s a great feeling mate. Absolutely stacked out at the moment and the bookings keep rolling in. Plenty of repeat custom too! It’s great to be making a living on the cars I enjoy the most. I dug the white DC2 out this weekend just gone and gave it some love prior to a trip to Oulton Park yesterday. Oil change, rear pad replacement, new exhaust and swapped in my short ratio box (more so for the plated LSD but I’d forgotten just how hard it pulls with it in!) First trackday in well over a year and a half. Went really smoothly, car performed impeccably and drove home without any major issue bar my idle valve playing up a little.

    Aaand another (bonnet now fastened down...) Thoughts on recolouring my alloys? I was thinking Anthracite but I'm not sure if I like the contrast that silver gives now...

    Colour update!! New (main) colour is 'Sprint blue' - I used to own an Audi TTS in this colour and absolutely loved it. So here we are! Not sorted the fixings for the new bonnet yet so excuse the fact it's not fastened down.... Black vinyl stripe to come soon and then sadly put a reg plate back on the front. Chuffed!

    I partially agree with you guys. I think trials gives bad habits too. I have also problems at jumping, this is my weakness on a MTB for sure. I really noticed that riding pumptrack. I used the wrong motion. And I can't remove my hands from the bar too! But on the other hand, I think trials helps me on technical jumps, that require one to be really active (you can either use speed or an impulse). Here is why: The motion differs from the bunny hop slightly: the steps stay the same, just the execution periods change. I understood this recently. The first steps of the bunny hop are to lower your chest/body (1) and then to push against the ground (2). Then you move your upper body backwards to lift the front wheel (3). But if you want to go really high, somehow you have to "push against the ground". As you do during some static hops too. When jumping a kicker, you will do the same. But the pushing (2) is more relevant in this case than pulling from the bar (3), due to the kicker and the angle of your body with the bike/ground.I understood this while trying to bunny hop higher. So trials helps me a lot there. As soon as I understood this, I did some progress in DJ. I am still not good, but at least I think I understood the correct motion and it works well on some doubles on the pumptrack . One other relevant aspect: in DJ, you have to move your hips forward, to land front wheel first and to fly a nice curve in the air. This is similar to a bunny to front. You have to drive the motion of your bike. Trials helped me to get a better impulse with my legs on the jumps. I noticed this on jumps where the impulse has to be really quick (for example on a jump directly at the end of a berm) This is based on my experience and as I said, I am not a good jumper. So please feel free to correct me!

    Yep, +1 for doing some stretching. I found a really basic 5min morning stretch routine on YouTube that did wonders for me. It really doesn't take much to start get things moving in the right direction. Went climbing for the first time tonight and man alive, my flanks are achey today... skin held together which was a bonus, although I mulched my hand into the wall and have damaged something in my hand/wrist. Proprioception was turds the whole time yesterday, but fun nonetheless! Buying a house is also pretty sucky - we got past the possible issues flagged in the survey, but now we've found from our solicitor that their solicitor still hasn't replied to stuff that was asked way back at the start of the process. Still waiting for the Property Information Form which we should have had from the get-go. The fact they're really dragging out supplying it is a little concerning, and also fairly ironic considering they were giving us grief for "holding things up". Usual solicitors/estate agents email ping pong shit going on, but we're hopefully still going in the right direction.

    I heard that the 610 was going away, but there are still plenty of them available here in the States. I tried one of the newer Z1eHX and it's definitely beefier than the 610, but the 610 looks better. I'll stick with the 610 as long as i can find them.

    /continued. Herein lies the problem: It may have hauled shopping around like a right ol' bus but it also weighed as much as one. When I got her to go for a bod through the lanes the limitations of the 3spd showed through quickly - I persisted because of the simplicity of only having one twistshift and the fact you can't f**k up shifts on a hub gear - they're made for people as mechanically numb as she was (still kinda is). As she grew in confidence her fitness/ability grew somewhat linearly and I impressed upon her that she was rapidly out growing the bike's capability to the point she was doing herself a dis-service. "I can't do gears - I like what I've got" she cried, but I just ignored that stubborn nonsense and told her she was more or less going to have to lump it. (or put the brakes on her progression) "Oh It has to be a step though" Mam said. "Yeh but you've a step through now and the downtube is made of gas pipe but is still somehow flexy wexy - I watch you hit a bump and it pretzel's so bad I think you're gonna tank slapper yourself into 3rd degree gravel rash - f**k no!" "Then what do you suggest?" [many errmms later] "What about a Mixte? Would you ride a Mixte?" Many discussions later, after a demonstrative image search or 3, I got a lukewarm OK and went shopping. Insert a 1980 something townsend frame with fork combined with choice bits from the probike and a good rummage in my take off bins and something was cobbled together. Originally set up with some really rather awful twist shifts, the probike mudguards and pedals it quickly went through a couple if iterations before I got the combo right. What you see here is iteration no.3. Should have been like this from day one really. Introducing the world's first (and bloody only!) Sram X9/shimano TY15 hybrid rear mech - the spring side of the TY15 has had the post lopped off and drilled; so that is now the spoke side of the mech cage - remarkably it lines right up with the x9, and the mech bolt is hollow from factory so has been tapped M5 and fabricobbled to the hanger from another TY15/18. eBay jockey wheels finish it off. The only shit bit is there isn't that part of the cage between the jockeys to circumvent chain whip. It's sketchy/grubby/works like a charm in equal parts and there's a dirty part o' me that luvvs it At this point It's set up 8 speed shifter on a 7 speed 14-28 freewheel with the 14t locked out as the chain contacts the frame. It indexs out like a charm, you just set the cable to have two dead gears, 7 & 8, shift from 6 to 5, lock the H stop off and tension the cable like every other gear setup ever. Backing off the stop 3/8turn pretensions the cable and away you go. Being a downtube shifted bike originally posed some headache when attempting bar shifters - there are no cable stops; one; and two, the cable run is bottom pull: Yes there are clamp on cable stop - I fitted two on the downtube if you look close, but the only bottom pull mech I had spare is goddawfull and the 1st time out she man handled the front shifter and mangled the b*****d clamp on - pulled the cable reet though. The back gears are fine as they are lighter to the touch but this took more than one binky-esk brew and biccy headscratching session for the solution to present itself. The brake cable is meant to run down the centre there anyway so some boreing out with a stepdrill on a 90deg adapter later the brake adjuster provides a cable stop, and using the V-brake guide pipe/noodle was fluke. One top pull mech conversion complete. Some surreptitious use of another brake adjuster fixed the bollocks'd thread in the X5 shifter (from someone not me winding the barrel to infinitum and shredding the placcy threads). I half tapped it with an m8 taper tap then rammed the adjuster home screwing it in with water pump pliers - not pretty but it works solid!

    So this is pretty interesting: https://www.pinkbike.com/news/how-much-do-professional-mountain-bikers-get-paid-pinkbikes-state-of-the-sport-survey.html Some random facts from it - 21% of the top 40 riders in the UCI DH and XC World Cups, EWS and Slopestyle events don't get paid a wage from their sponsors (they may be paid expenses, but that wasn't covered in that survey). Nearly half of the top 40 downhill riders in the world are paid between $0-5,000 per year (again, not incl. expenses). It's pretty nuts that most of the riders in those disciplines are paid so little that they couldn't afford to buy the bikes they ride at retail price on their salaries. I assume there might be (must be?) some non-endemic sponsors helping them out, but still, they can't really be making much of a living with that. As a slight contrast, there's a stipulation for teams taking part in the UCI World Tour road cycling events that they have to pay each of their team riders a minimum wage of €40,045...

    It was dusty yesterday. Almost lost it on a few fast corners. Silver lining was how clean me and my bike was. Picture taken roughly 10 miles into the ride.

    Electric planer lasted about 20 blocks before death, and the hand planer was pretty much 1 and belt sander is almost 1 tbf the tool that broke did the whole first batch of around 1500 a load of work over the years then 600 of these blocks - it’s just I had not intended to ever get a new one as all the major jobs in the house are near enough done! It just all seems to be going wrong and costing time and dollar at just the wrong moment.

    I decided to revisit this today, aaaaaaaaaand..... It worked! (I think) The major differences between my epic fail last time and my (touch wood) success today are brand new tyres and decent tyre levers. The old tyres were the biggest problem I believe as upon closer inspection they were very deformed and the beads never really seated properly even when using inner tubes, my wheels looked buckled if I looked at them while they were spinning but it was only the tyres, the rims are both very true. The tyre levers also made a massive difference by making things much much easier, I used Pedros tyre levers which didn't even feel like they were close to failing whereas during my previous attempt I snapped a couple of Park levers. So as it is I put one layer of black Gorilla tape around the rims, full width (thanks Ben), installed the valves (the tighter side of finger tight) making sure the rubber cones did not deform, wrestled the tyres and Rimpact inserts in and pumped them up to 60psi with a normal crappy no-name eBay floor pump (not even a tubeless type) and so far they've held some pressure for around an hour but with no sealant and technically not tubeless-ready tyres they won't hold much pressure for long. I wasted all my sealant on my last attempt but I work nextdoor to a bike shop so I'll get them to add to sealant tomorrow if they have time and make sure the beads are seated properly as just like last time I never got any bead popping sounds while inflating but this maybe because the tyres are so damn tight on the rim that they seated themselves while I was installing them, maybe, this would also explain how I managed to inflate them with the Worlds crappiest pump but more than likely I just couldn't get enough pressure built up quick enough with my pump so hopefully the bike shop will get them seated for me.

    Indeedy. They admit in this video that they should have done it a lap later: Red Bull complaining about track limit enforcement after the fact too - Helmut Marko claiming they lost a win, pole and fastest lap because of track limits. They arguably did 'lose' those because of the track limits violations, but those came up because their driver violated track limits. It's not hard to work out. He overtook Hamilton while he technically wasn't on the track. He slid outside of track limits in qualifying. He drove outside of track limits on his go at fastest lap. I'm not in an F1 team, but even I knew that they were enforcing turn 14 (and 15) track limits at Portimao, and when Max was having his tilt at fastest lap I saw that he went beyond the red and white curb and called it immediately that he'd lose the time because of that. If I'm just a random dickhead and I know that, how can a person paid millions to drive an F1 car not be aware of that? I'd be pretty embarrassed about that and wouldn't really want to draw attention to it, rather than saying I was just totally oblivious to it and didn't know it was happening. I guess Red Bull culture is to never take responsibility for anything, so it does follow that pattern. I do hope Max gets a crack at the title as he is a great driver, but that attitude at Red Bull is preeeeetty toxic. A slight contrast to how Mercedes appear to be happy to hold their hands up and accept when they've got something wrong, e.g. that video up there.

    The 1370kg max load rating for the Z1eHX compared to the 1200kg max load rating for the Z610 HX should give you a bit more confidence too. It is a stronger chain overall. That said, all chains will eventually snap, so it's best to replace them periodically (depending on how much you ride).
