'Blade Saver' for L type rear mudguard and roller axle replacement 1122334000091

After many requests we finally have new stock and an easier production method for the Blade Saver for Brompton L type rear mudguards. The holes are now very precisely drilled in a jig, so no inaccuracies possible.

The purpose of this brace is to prevent cracking of the mudguard blade. In case you never experienced this, it's caused by the weight of the rear wheel being absorbed by the stays and the blade each time you fold your Brompton. Finally after a lot of folding and maybe on a cold day rushing to the train it suddenly hates you and might explode...but not with the brace 🙂

Material: matt silver anodised aluminium or matt black powdercoated aluminium

Weight: 27 grams

Assembly instructions:

Best to remove the rear wheel before assembly. At least deflate the tyre, but even than it's quite fiddly to add the plates and little nuts on the underside so best is to remove the wheel. Remove all the bolts which hold the stays and the roller. Try to not lose the nuts. Release the brake cable from the caliper, unscrew the Lower Stop Disc and move the brake caliper to the back with the mudguard still on the caliper axle. Add the Blade Saver, the concave-flat alu washer and push the brake caliper axle through the rear frame again. Add all three washers and tighten the Lower Stop Disc fairly tight, but don't squeeze the bridge tube flat. Screw in the supplied longer M4x12 bolts. First at the vertical stay and and next the roller bolts. Screwing them through the Brace plus the blade might be easier than just putting them through as both parts might not align perfectly. For adding the roller bolts it might be necessary to use a pick or other thin/sharp tool through the hole at the end to align the hole in the roller with the hole in the blade. Push or screw the bolt through the other hole, than finish off with the last bolt where the pick was.

You can choose to not use the stainless steel oval-ish plate which holds the vertical stay. The Blade Saver has the same function. But when you do use the plate it might give a bit of protection to prevent the Brace from scratching on the ground. If you use it you also have to use the longer M4x12 bolts and the washers supplied. Just as on the photos.

Also in the kit is a M5x25 allen bolt which can replace the riveted axle of the roller. Most of the time the roller rotates heavily. The Bolt solves this issue. Drill out the riveted side using a 5mm metal drill. Just drill away the curl/rivet on the outside. Than push or hammer out the axle. Use bearing grease on the bushing before putting everything back together again with the M5 allen bolt and lock nut. The lock nut allows you to exactly adjust the play of the roller. Find the sweet spot at which it rotates freely but doesn't rattle.

Good luck and enjoy your rides!
