SpēdDial questions you may have and our answers:

  • Why did you decide to offer SpēdDial hinge clamp kits? We were frustrated by the time and dexterity required to unfold and to fold our Brompton. We discovered others offered products to solve this problem, but they were expensive and only partly effective. Our idea was to produce a solution that was as effective as possible and to make it affordable by combining a few custom mass-produced parts with inexpensive off-the-shelf components.
  • How many turns does it take to tighten the clamps? SpēdDial takes 3-1/2 turns.
  • How heavy are SpēdDial kits compared to stock Brompton parts? SpēdDial kits weigh 119g (4.2 oz) for long wheelbase (post 2004) Bromptons, 122g (4.3oz) for short wheelbase. Stock parts they replace weigh 100g (3.6 oz).
  • Why is it so hard to tighten the nuts? For a tight fit, US Standard thread nuts are mated to metric bolts. They start threading easily, then tighten up semi-permanently. Bolts are hardened automotive grade 8.8, so they won’t wear out. (The Nylon ring need not engage for the assembly to work properly.
  • Why are there two sets of bolts? Four standard sized bolts (2 for each frame type) were cheaper than two custom bolts that would fit both.
  • Why do we reuse the old washers? Washers pressed into the handles must be a precise size. They are custom made for Brompton. Similar washers may cost only a penny apiece, but identical washers might cost us 100 times that much.
  • Are replacement parts available? In the unlikely event that they need to be replaced, M8-1.25 bolts can be purchased at auto parts or hardware stores. Excluding head height and depending on frame design, they are 50mm or 55mm long and fully threaded. Nuts are US 5/16-24 jam nuts
  • What if the nuts become loose? If nuts become loose from repeated installation, screw them all the way onto the bolt, to thread the plastic insert, then install them insert first. Replacement nuts can be purchased at SpedDial Europe by sending us an email.
  • How durable are SpēdDials? SpēdDial parts are as durable as those that come stock on Bromptons. Handles are glass-filled Nylon.
  • Do SpēdDial kits require lubrication? Not necessarily, SpēdDial plates are waxed for protection and to avoid sticking. Bolts come pre-greased with wax. However for ultimate longevity it’s advised to assemble with a small amount of multi purpose grease, PTFE grease/oil or bearing grease on the big washer, the spring ends, and the bolt’s thread. For best performance this should be repeated on a yearly basis.
  • How hard is it to remove the handles for shipping? You would have to wrench off the nuts and collect the various parts. You would have to replace worn nuts from time to time. In the future, we may offer SpēdDials with quick release handles.
  • Do SpēdDials come in different colors? At this time SpēdDial comes only with black handles and clear anodized aluminum plates. If there is demand, we may offer black plates and perhaps handles of most-requested colors.
  • Can I purchase SpēdDial directly from the manufacturer? No, SpēdDial is sold only through dealers and SpedDial Europe. By buying offline at a local dealer, you can try out the product before buying it, and benefit from their installation expertise. When buying online in this webshop, we like you to know we did our very best to serve you well with lots of honest information, text and video’s and we hope you find all you need before purchasing a SpedDial kit.
  • Where is SpēdDial made? SpēdDial is assembled in California from parts made in the USA and Asia.
