In a couple of words the I find the bike solid and predictable and it only took a couple of miles of riding it before I stopped thinking about it and got to focus on the terrain and scenery.

    One point to make (for my build, anyway) is that I made no attempt to make this bike lightweight and it is not--it's a full 4lbs heaver than my summer ride and while I haven't seen much of a difference in speed on my rides I feel it in the form of a little extra lactic acid on the efforts.

    All of this steel makes for a really predictable ride, though, and I really like how it's handled in the wind. We've had some wicked gusts during this moody early spring and the bike tracks steady and true.

    I had my other bike professionally fit and I got the stock Breezer parts as close as I could using the measurement sheet I was provided but I still felt like I was reaching a little more for the bars. I lined the two up and while the pedals and seat matched up perfectly, lo and behold the bars are 2.75cm lower on the Breezer, so I'm off to find another stem to make up for that.

    It's kind of interesting to see the two bikes side-by-side to compare the "compact" geometry of the Merlin against the Breezer. There are very noticeable differences in the top tubes and head tubes.

    There has been some discussion on this thread about the Venturi being a "racing" bike and with some lightweight wheels and part upgrades this could very much be the case but now that I have some miles in I find the choice of a compact crankset an odd one. Unless you live in a really hilly area I find I'm always in the smallest cogs when in the small chainring and over geared when transitioning from the small chainring to the large. If the bike hadn't come with these parts I would do a 39-52 in the front with an 11-27 or 11-28 in the rear.
    No, the Venturi is not particularly light; with a pretty mid-grade build like mine, my M/L size bike is hitting the scale right at 20lbs fully dressed (pedals, cages, Garmin bits). I don't know what the frame/fork weigh, but I'm pretty sure a Sram build with some 1500g wheels and lightweight saddle (i.e. non-SMP!) would be about 18lbs. Decent, but far from the weights easily achievable with aluminum or carbon.

    Anyway, I'm running a standard drivetrain-- 53/39 and 11-25-- which works for my strength level and rolling terrain. Whether that's enough to make it race-worthy I'll find out next month when our local spring crit series opens!

    Thanks strayduck

    There is a used medium frame on ebay now, which equates to a 55.5 ett.

    I usually ride a 54.5 top tube with 73 seat angle, so not a huge difference. I am just wondering, since the breezer has a tapered head tube, if the venturi ETT is measured from the back of the head tube or from the fork's steerer tube. IE, would you measure to the wider bottom of the cone spacer above the top tube or to the narrower top of that spacer.
    I looked at breezer's website and their geo diagram was no help, it has the ETT measured from seat tube under the top tube to the fork. weird.
    Anyone took a tape measure to theirs?
    I am riding 175 miles so kids with cancer can go to summer camp for free. You can help:

    Hey @bikebreak: When I measure from the center of the top of the head tube to the center of the seat collar (keeping the measuring tape level with the ground) I get 58.5cm which perfectly matches Breezer's spec for my 2012 XL frame.

    The Venturi doesn't have a tapered head tube, and even if it did, I don't think that would make a difference in ETT measurement, which is always-- in so far as I have seen-- measured center-to-center, on the horizontal, from the TT/HT junction to seat tube/seatpost.

    The Breezer diagram is pretty useless, though, as it seems to show ETT from center of what might be the virtual fork crown (!) to back of seat tube! In fairness, their diagram is not indicated that's the ETT, so maybe the diagram is just some in-house diagram that's used as decoration, and not meant for reference. Strange and confusing, in any case. EDIT: I suppose that, on the M size frame with parallel HT and ST, that distance would be the same measured anywhere between the centerlines horizontally.

    Strayduck hit the same numbers as officially listed measuring c-to-c at the top of the HT, but I suspect because the top of the HT is maybe a mere 2mm above the TT, that the actual difference from that point to 10mm (or whatever it is) below that to the center of the HT/TT junction, is within the error range of the measuring method.

    One frame, two bikes!

    Move the saddle forward, tri bike. Move the saddle back, road bike.
