  1. I'm wondering if putting thracian wheels and stelvio tires
    on my V-rex would improve my speed significantly or not be
    worth the expense. I've had the bike for almost a year and
    3000 miles and still feel slow. -Thanks

  2. just do some heavy training on a fluid trainer for about 1/2
    to 1 hr.a day and then that will make you faster. Thank you

    No.

  4. I've "been there" and I've "done that" You can pick up part
    of 1 mph with equipment. I have tried LWB, Low racer, and
    High racer.Wheels, tires. Each gives a bit of placebo effect
    at first, BUT, in any type of time trial situation, none of
    those things makes me an "over 20 mph" person. It would
    appear that "It's the engine!!!!!"

    The lighter wheels allow greater acceleration. The weight
    reduction aids climbing speeds, but not much effect of
    straight and level.

    On the other hand, downgrades will slow you down
    significantly. My first SWB started life with 65 psi Wal-
    Mart road tires. 13 mph was HARD to maintain. Tire and wheel
    change and right back to 16/17 cruise.

    Miles of Smiles,

    I ride both a VREX and M5 Shock Proof. I can say the Rex is
    no slow ride. On level ground, sustained speeds in the high
    teens are no problem for this bike. I would try just the
    Stelvios before buying the new wheelset. The wide stock
    tires on the VRex are there to provide "passive suspension".
    Narrower, higher pressure tires should speed up the bike
    nicely. If the Stelvios don't meet your need for speed,
    you're probably better off spending your money on a fast low
    or high racer. For significant increases in speed, a higher
    bottom bracket, better wind profile, and maybe, a hard shell
    seat are most desirable.

    First of all I am a big proponent of working on the "engine"
    first and that you will see the biggest gains from
    improvements in this area.

    However I also do beleive that you will also see some
    improvement with a tire change and less so with a wheel
    change. On the equipment side I would suggest you switch to
    the new Stelvios with the "Raceguard" belt, which is a more
    durable version of the Stelvio. I have lots of tires both
    559 and 650c tires for my Strada/Corsa but have started to
    use the new Stelvios and saw a 1.0 mph increase over the
    Specialized on the same exact route, identical beats per
    minute, and a shorter riding time. And for $80.00 that is s
    pretty good bang for your buck.

    I agree with Pat. I would first deal with the tires.
    Stelvios are very nice. Another fast tire is the Continental
    Grand Prix. I ran them on my 2000 V-Rex and was very happy
    with their speed and performance. If you want a little wider
    tire with what I have discovered is low rolling resistance,
    the new Kenda Kwest 1.25" tires are nice also. I am
    currently running them on my 2002 V-Rex. I know that better
    rims etc. are highly prized, but I have always found the
    Rex's DA 16 rims to be good quality and decently light. Not
    like some of the Velocity rims, but certainly acceptable.
    And if all else fails, then you can always do what another
    poster suggested one time. For an immediate 40% gain, flip
    your cyclometer over to kilometers.

  10. A V-Rex is fast. Adding tires, decreasing weight etc. might
    give you a small increase in speed, but if you cannot make a
    V-Rex go fast...you might want to keep your money. I have
    had two Greenspeeds, a Rocket, Carbon fiber uprights etc.
    While I have had a few issues with Rans, I have to say that
    the V-Rex is a good bike and is fast. You can spend a lot of
    money on tires, wheels and other lightweight stuff, but you
    won't beat a regular V-Rex by more than a few hundred feet.
    Not worth the investment.

    I have a 2001 Vrex and did a few things to get ready for
    last years Ride for the Roses. First thing I did was get rid
    of the front shock and replaced it with a rigid fork (local
    shop did actually). I replaced the stock tires with Conti
    Grand Prix's... I have heard a lot of talk about the
    Stelvios but had never seen them in action first hand. I
    have ridden Conti's for years when I was upright and have
    been very pleased. They added about 2mph to my average for a
    50 mile ride. I also did a thorough clean and tune job.
    You'll be surprised how much faster you'll ride when you
    aren't busy thinking about that creak!

    I too am curious about the Thracian's. Has anyone here used
    these on a Vrex? How did you like them?

    The above neglects to mention the fairing and bodysock, so I
    am uncertain if it was included in the "Not worth the
    investment" category.

    Based on my observations of performance of bikes with and
    without bodysocks, I would suspect that an average strength
    rider would see an average speed improvement of 20-30% over
    flat to rolling terrain by adding a front fairing and
    bodysock to a RANS V-Rex - certainly worth the investment if
    the rider cares about speed.

    The most likely thing to creak on a V-Rex or other RANS bike
    is the seat mesh rubbing against the seat frame.

    Well, then is it SAAB and FIAT or Saab and Fiat? (Although
    Saab bit the bullet at least in the U.S. and even added an
    additional 'A.B." after the Saab, which I guess means its
    Saab from now on..." I thought they would finally resolve
    the FIAT or Fiat thing by gonig under, but it looks like
    they will survive a while longer with the latest comeback.

    I don't know if on a short wheel base bike the percentage
    gains that Tom has listed would be correct, but I
    certainly agree that the combination of a fairing and
    bodysock should bring a very noticeable increase in speed.
    While getting up hills may be a little tougher with the
    added weight of the apparatus, overall the increase on the
    flats and descents should significantly improve your
    times. My wife's riding performance on her Gold Rush with
    the fairing was decent, but when she adds the bodysock it
    goes to exceptional. On the flats with a light tailwind
    she can cruise (not push) close to 30 all day. All I can
    do is hope that the ride is far enough that she'll tire
    and I can catch up.

    At least SAAB (Svenska Aeroplan Aktibolaget, where
    Aktibloaget roughly translates to "Inc." or "Ltd." and is
    abbreviated AB) and FIAT (Fabbrica Italiana Automobili
    Torino) are acronyms, and thus have good reason to be
    capitalized.

    Is there an acronym for RANS? I've never seen one. Never
    heard the origin of the name, and I don't see it anywhere on
    the RANS website. Always figured it had something to do with
    Randy Schlitter's name. If his middle initials are A. N.
    then it makes sense to capitalize RANS; if his nickname is
    "Ran" and his company is "Ran's," then it doesn't.

    Yes, sad to say, and not just in the US. GM bought out SAAB
    about 7 years ago, and the cars they've produced since then
    have not lived up to the previous standard. I've been
    driving SAABs for 18 years, but my current one is likely my
    last -- unless I decide to buy a 10-15 yr old pre-GM model.

    Last summer I bought a set of Stelvios from Schwalbe through
    their web site. I also suggest getting a Park tire bead jack
    to help install the tires unless you have strong fingers.

    BTW the Stelvios were about $43 ea.
