  1. Thanks Mark, I have measured it at 19mm. hoping that the the company I have found will ship to the U.K. it’s a 22mm so if it’s a little too wide I’ll shave it down. crazy that this part is so hard to come by.
  2. Thanks Luke. I checked Tarty and they are out of stock of what I need. Where can I find the ID? Sorry new to this! im speaking with HB Trials from Canada, who have some 20mm and 22mm stock. I’m hopeful one these will fit
  3. Hi all, searching for a Star Fangled Nut to fit a 24” echo urban tapered fork. cannot find this part anywhere despite searching the net for a considerable time. Any ideas on alternatives? I’ve tried to file down a 1 inch star nut, to no avail, the diameter of the base of the nut is too large for the thick steerer tube. any thoughts appreciated! thanks
  4. Generally wish people had told me not to stop! I took a very long break, but back on a trials bike now and loving it!
  5. Hi Adam, thanks for the reply, not sure you will hear the noise as it’s pretty faint. im probably just over thinking it. I’ve added a couple of videos for you. thanks IMG_3012.MOV IMG_3015.MOV
  6. Hi all, My first post here, sorry if it’s in the wrong place. recently, after a 20 year gap, I brought a trials bike again. It’s an echo GU 24” and I love it. Absolutely loving getting back into things, especially as previously I was rather young with little money and my bike was more like a tank I recently got a puncture and had to remove the back wheel. since resolving the issue, I’ve had a strange noise which I am struggling to understand. the noise is a very dull grind and a small vibration which can only be felt while spinning the back wheel, while it’s lifted off the ground. there is no noise or vibration when any pressure is on the cranks. The noise doesn’t occur when the wheel is spun backwards. I’ve taken the tyre, tube off and chain off and spun the wheel in the drop outs - no sound or vibration. I’ve checked the BB by spinning the cranks - also no sound. I’ve check my wheel is in straight and there is no pad connection to the rim. The wheel is pretty true, a very faint wobble. I noticed a couple of things today firstly that the chain slack point causes a little wobble of the chain when coasting. This seems to be in Rhythm with the vibration and the sound. I’ve also noticed that the chain right (potentially not the correct terminology is not a perfect circle around the cranks (I’m not particularly sure this is the issue or if it’s even possible for a perfect circle) it’s a very small increase in the gap between what holds the chain ring and the cranks. I’ve added a picture of what I am talking about. The increase in gap size is marginal. my feeling is that it’s the chain loosening off and increasing tighteness and the wobble which comes with it that is causing the issues - I think this as the issue is not present under pressure to the cranks (chain stays tight obviously). that said, I am not sure and it’s a little unnerving. I am not so worried about the noise and the vibration if there is no need to be, I’m worried about catastrophic failure of moving parts while riding. any ideas or thoughts would be appreciated! thanks
