  4. Old Trials Vids (Huge collection on YouTube)

    in Videos

    Posted

    Evening all!

    I have begun uploading my collection of riding videos and clips to Youtube. ~200 uploaded so far and another ~68 to do over the next few days (Youtube limits the number of uploads per day). A few vids have been removed for copyright music already so we will see how this goes!
    I obviously don't own the rights to any of these videos so please let me know if you want me to remove any (nothing is monetised).

    Apologies for diving straight in with a question. As usual, lots of cool things going on in this thread..it's hard to keep up! :)

    So I've had a nightmare few days with my LC. I thought it would be a good idea to upgrade to Brembo's from the LCR...I now have an undriveable car with a very spongy brake pedal! There is definitely something wrong with the brakes and am I wondering if I've broken the master cylinder somehow? The reason I say this is I bled the brakes with an Ezbleed as usual (all seemed to go fine) and when I finished I used a syringe to remove excess brake fluid from the resevour. However, every time I remove fluid, it seemingly re-fills itself?! (I literally watch the fluid rise back up). I have never seen this before, it's very odd! Apart from poor braking/spongey pedal I'm also getting what feels like ABS kicking in at low speeds (could be unrelated/sensor?) as well as a grinding sound noticeable when turning right. I think the RHS disc is catching on the metal pad shims slightly. All in all I'm now contemplating if it's worth keeping this 190k mile car on the road or going to buy a Mk2 Octavia VRS (Petrol or diesel - undecided)..

    Edit: I can also hear a slight hissing noise when pressing the brake pedal when the engine is on. I don't think it happens all the time though (will check).

    As usual, any help is greatly appreciated!

    That's brilliant! It makes you wonder how some people think.

    Jumping in with my latest car news...

    I'm STILL trying to decide what to do next. The LC has 171k miles on it now but is still going strong. However, some rust is starting to appear around arches and the bodywork/wheels aren't in the best condition. Probably not that surprising as I'm still doing 350 miles a week.

    So half of me still wants more power and the other half would like better fuel economy. This has brought me to the following options:

    1. Keep the LC, do nothing until something major breaks.

    2. Keep the LC, buy a hybrid turbo etc. (Would also need engine rebuild?)

    3. Buy a 2.0TFSI (VRS or A3) <£4000

    4. Buy a 2.0 CR (VRS or A3)

    5. Quit owning 'quicker' cars/accept people overtaking me and buy something sensible.

    Any opinions would be appreciated.

    I need some help with my LC please :)  Over the past few weeks the car has been hesitant to start when warm (i.e. if I drive home and turn the engine off then try to start it again a few minutes later) It then idles high for a few seconds. I've also notice what I'm pretty sure is a boost leak when overtaking etc. I think the two problems are unrelated but might not be? My current thoughts are leaking injectors?

    I have to admit I do feel it has died compared to the "good old days". Personally I have recently purchased a 24" to try and get me back into riding...I have to admit it's working so far! However, I do feel as we get older we see things differently and nostalgia plays a big part.

  13. Disc Rotor Adaptor 180mm to 203mm

    Hmm, it looks as if the equivalent shimano adaptor in 180mm might do the trick...

    Edit: On second thoughts I noticed the original Avid mounts appeared to both be identical. Does this mean maybe the Front 203mm Shimano mount will work on the rear?

    So the new rotors and adaptors arrived today. The front works fine but the rear caliper sits too high on the rotor :S The adaptor appears to bring the caliper more towards the front of the bike than the previous one.

    I've attached a photo of the rear adaptor I purchased. Any ideas?

    Nah, that sounds like you've got either a contaminated rotor or contaminated pads (from your "Good when wet, then gets worse" comment), so switching both out would be a good call.

    Just as a random other point of order, don't use disc brake cleaner on them :P

    I suspect it is contamination. Oh, what's wrong with disc brake cleaner? :huh:

    If you've got BB5s (which I think the Ion has from standard?), then before going to bigger rotors it might be worth giving the Trialtech Sport Disc Brake Pads a try.  I've used them on my Hope and my Magura brakes and the difference in braking power from normal pads is pretty amazing!

    Hi Mark,

    Yes BB5 on the front (which works well to be honest) but I've upgraded to an old Saint M810 on the rear. However, the brake just isn't performing well at all. It's brand new (I got very lucky on Ebay!) with sintered pads and I've given it a fresh bleed. If I wet the rotor it works amazingly but progressively gets worse after a short time. I've had quite a lot of rides on it now and followed all the normal bedding procedures so something isn't right. I thought starting again with a new rotor and pads might help things but maybe I am going over the top?!

    Are your brakes post mount? You don't mention. Have you checked that your forks are ok with a 203mm rotor? The large rotor increases the stress on the forks IS mounts so you need to check the max rotor size the manufacturer recommends.

    Brakes are both post mount. Warranty only covers up to 180mm which seems fairly standard but I'm willing to take that risk.

    Did you cut the keyboard and the can in the same project, or were they done separately?

    Cut out of a single billet of unobtanium!

     

    Manuel, if you want to get an idea of what's involved in Fusion 360 and machining parts in general (although mainly aluminium) then definitely subscribe to NYC CNC: https://www.youtube.com/user/saunixcomp

  24. 2017 Czar 24" Range - Tartybikes?

    in Trials Chat

    Posted · Edited by David

    Hi all,

    I've noticed the release of the new Czar Ion 24" on tartybikes. Having a look around there appears to be several versions of this? Before I potentially make a purchase, does anyone know if there will be any new or upgraded models released over the coming months?

    I've noticed the Ion Pro and Neuron?

    For those that do some of their own or have their own - is there any good free software I should be looking at? And on a scale of 1 (taking a picture and sending it with an iPhone) to 10 (pointers to pointers in C) how hard and time consuming is it to learn to design and program something in?

    In terms of taking designs from CAD to CAM it's quite easy. I'd definitely recommend Fusion360 (it's free!) as it's a completely integrated environment and very easy to learn. A lot of the skill is involved in selecting appropriate "speeds and feeds" as well as all the setup involved in work holding the material you are going to cut. If you are doing simple "2D" parts from sheet then this removes quite a bit of complexity but still requires some thought.
