    I got this folder on ebay - a Revan

    I got this folder on ebay - a Revan, no idea where it comes from. Haven't googled it yet.


    Steel frame, 35mm seat post, coaster brake, 406 wheels - surprise - alloy rims, Pletscher carrier rack, alloy mudguards.


    It folds to the right! Protected drivetrain.


    To fold, loosen this steering post bolt/lever, it works like any quill stem, but simultaneously loosens the bars so these can be rotated down.


    Inside the seat post, I found this pump!

    Oops, sorry, no, I installed a spare Brooks B17 I had. The original saddle is a black plastic padded affair similar to the Raleigh Twenty's.

    Googling yielded no results.

    I have a Sachs Torpedo Duomatic geared hub for it. Coaster brake which also switches between the 2 speeds. That will preserve the potential clean lines. A second wheel will be for a fixie as per caotropheus's suggestion.

    I just realised this bike has a better fork that the R20. The R20 fork dropouts are just the fork tubing pressed flat and slotted. This one has a brazed dropout.

    I think I'll be giving this fork the same rake-reducing treatment I gave the R20 fork.

    One thing that bothers me is the lack of a bracing tube behind the frame hinge. It puts a lot of stress on the back joint where the downtube joins the seattube. I am toying with the idea of having a strut brazed in there. Any opinions on this?

    I agree with you. My Kama bicycle also lacks this bracing tube but the downtube is pluged to the seat tube by a massive lug. Beside that I only weight 54 km and I do not believe I can apply much stress on the frame. Your frame is just a pipe welded on a pipe and you should braze a strut.

    Jur, one final question: Are you going to use 451 rims?

    I thought I would, yes. I checked and they would fit.

    I have a spare 406 front wheel and a matching back wheel on a SA 3sp hub; I was thinking of using that for the Sachs Duomatic hub I'm getting except the holes don't match (36 hub, 28 rim) so I have to consider spoke lengths carefuly. That may be interim.

    I stripped all the cluttering items off last night and it's looking a lot better already. At this stage it reminds me of v1nce's R20.
