Two weeks and 140 miles into ownership of my Metaphrastic and two aspects could clearly be improved upon.
- Chain slap onto the front fork / head
- The harshness of the ride
For those with a Metabike or other recumbent high racer, here are a couple of ideas which may work well for you too. I wanted to fit some short lengths of chain tube where the chain passes the fork to protect again chain slap (on rough Lancashire roads) but I could not readily see how to attach them. Then Mrs W came up with an idea which was so simple and elegant I could have kicked myself for not thinking of it. The chain crosses near the fork, so simply by putting a short length of tube on power and return sides at the point of cross over and then joining the tubes where they cross you find that without any bracket or spring clip that the tubes simple hold in place. See the picture below.
Then I swapped out the two rubber spacers between the lower seat fixings and the frame for three…. …..3/4 inch (rubber) tap washers! I wanted to get a slightly greater gap between the chain and the front of the seat, but the slightly softer compound of the tap washer combined with the greater depth of rubber has made a very significance to the ride. Really it’s like going from an aluminium frame road bike (well of course that is what it is) to a steel frame tourer – but without any loss in boom stiffness. A pot hole is still a nasty experience, but the high frequency vibrations of poorly resurfaced roads (chipseal for my American readers) is gone completely. The change is, well, truely a Metamorphosis!
