    I don't think you'd regret going for Maguras over V-brakes. I only wish I'd
    got disc brakes when it's time to change a rim, which isn't that often. Of
    course, if I had bought disc-brakes I might see this differently. I find
    that HS-11's are plenty good enough, if you're looking to save money.

    The flyers I have don't list front suspension as an option, but the Nazca
    website now shows a picture of a suspended fork as an option. As they're
    in the middle of redoing the website the text is limited to placeholders
    at the moment, but from the image and some googling I think it is a Zoom,
    model CH-190(AMS) 20.
    Specs:

    Wheel size: "20"
    Crown pitch:100mm
    Features:MCU+Spring pressure system
    Crown:Forged 6061 T6 AL crown
    Outer leg:One-piece nluminum
    Stanchions: Ø23.9mm butted Hi-ten tube
    Brake type😄isc brake and V-brake compatible
    Weight ¡G1.2kg
    Travel¡G30mm

    Anybody any experiences/opinions on this?

    I've owned recumbents with 20" wheels, but I never yet felt the need for for
    front-suspension on comfort grounds (the obvious reason). But you might
    find it worthwhile for other reasons.

    One is that my bike put most of my weight on the small 20" (406) wheel, and
    it got loads of pinch flats whenever I hit a pothole or stone in the road
    (from looking at it, your bike might be better in this respect). I later
    got a larger 451-size front wheel with a bigger tyre, and this seems to
    have cured the problem.

    My second reason is that recumbents fall down faster if the front wheel hits
    any imperfections in the road - at least this is my embarrassing
    experience. I suspect that suspension may help on both counts. I'm
    interested if anyone can confirm or deny.

    It does look smooth, without any obvious coils etc.:

    I've also heard good things about the Pantour suspension hubs. I have
    precious little first-hand experience of either, and a SON dynamo that
    limits my options.

    Thanks, Roos

    Hope you don't mind, but I crossposted to alt.rec.bicycles.recumbent. A
    newsgroup in desperate need of recumbent-related posts such as yours.

    The rear Magura Clara on my Speedmachine is contaminated by oil (previous
    owner? shop mechanic?). A new pair of pads from Magura is (with tax and
    shipping) $37 US...not something I could find at a local bike store. How
    much are V brake pads? A tenner? By itself the front disc brake does a great
    job of shedding speed. In panic stops, the V brakes on the V-REX could get
    me sliding off the seat. Hard to compare that to the Speedmachine as the CG
    is 5 or 6 inches lower.

    Suspension on both ends...like the commercials say "priceless". Not only is
    the ride more comfortable but control increases. There's a section of the
    local trail that has about a hundred yards of asphalt upset by tree roots
    under the roadway. I'm about 5 mph faster through the section than I was
    with the V-REX, and my vision doesn't blur, and no fillings fall out when I
    hammer through. However when I took a cornering line that went through wet
    slimy leaves on the trail, the bike went down in an instant. No warning,
    just a slide with a bunch of mud getting jammed up my ass crack. Glad I had
    a pannier on the rear derailleur side. No damage except for aluminum being
    ground off the right pedal cage.

    I've slammed through potholes that I thought would trash a wheel/tire/tube,
    but there was no damage which I rightly or not, attribute to the suspension
    absorbing the hit, saving the rolling stock.
