Interesting to read about frame sizing. For instance, I personally prefer road bike frame to be tad shorter than suggested. If I have to choose between frame 58cm, 59cm or 60cm (for my 6'1" body), I'd shift towards 58cm or even smaller frame. It's just about that feeling. For touring bike I'd go with a larger frame. How's it with you? How do commuting, touring and racing bike sizes differ in your case?
Nishiki Linear ... that's quite something, never seen frame like this in real life! Must be 28" rear and 24" front wheel, right? What are the components? I certainly can see Mutant stem fitting onto this frame; adds modern touch and blends nicely with the black tones (white, black, red color play).
Basing most of my riding style on racing/fast touring (for my age); I tend to go with slightly larger frames (54cm-58cm ST) in height and length than my optimal frame size (52cm ST/54cm TT). My commuting tends to be criterium/interval style riding so, yes a nice nimble short/compact/stiff frame is most suitable; a lot of sprint style "stop and go"; during which I use the 51.5cm Batavus "Criterium" (Reynolds 501 tubeset) slightly modified for "cross/off-road" with 30mm tires; certainly not set-up for racing/speed, just general training/"multi-use".
I have been "sized" for a bike once; my first brand new bike ('79 Peugeot sport frame) and that was just to make sure I could "stand over" the bike at age 17yrs old. There was no thought and/or concern as to crank or stem length. I rode that bike on a 1500 mile winter tour at age 18 and never thought twice about riding comfort; young body, no injuries (bike related anyways). Now my concern is mostly about length and not height; injured back, shoulders, knees, and ribs affect the frame size and type of riding; time trial (up to 25-30 miles @ +20mph, hopefully!), medium distance fast (15 to 30 miles @ +18mph), or long distance moderate speed (30 miles @ 15-18mph). After doing 30mi/50Km on the "Linear" a couple weeks ago, my whole back felt sore, but doing 15mi/25Km on the same frame riding hard feels just fine. I'm regularly being told that I ride too large of a frame, but after riding big frames for the last 35 years; the "small frames" (actually my size) feel a little odd. That could be due to the smaller frames having inherently more stiffness due to shorter tubing and a overall lower frame weight, and center of gravity.
I "train" on a 51.5cm "sport criterium" frame (my size), but "race" (informally/unsanctioned) on frames 54-55cm and larger. Probably because my better bikes are bigger frames with better performing components. The last time I "raced" was on a 54cm x 54cm aluminum ALAN/Tommaso frame; a job that could not be handled by the smaller/"better fitting" Batavus frame.
Sizing is such a personal issue, 2 people can have the same build, inseam, and reach; but each might feel more comfortable on frames of significantly different size/geometry used for the same purpose. When I was touring in my younger days I had a substantial load on my back so being too upright was worse than being too stretched out when doing over 100mi/160Km. Now being that my rides are shorter and I rarely ride with a pack on my back I am not concerned as much about "riding position" unless seriously training/racing in order to have a more aerodynamic position. The nice thing about the "Linear" is that you get used to keeping a lower position (you don't have much choice), and then when I get on my other regular frames, being in the drops isn't as uncomfortable. Having bikes that I ride with frames from 47cm-61cm, height never really affects me that much as I'm not getting on and off the bike very much; the top tube and stem length are my biggest factors regardless of height. The most uncomfortable I have felt was on a 43 cm sized Quintana Roo frame (time trial/tri bike) due to the top tube length, not the height. I have a "junior" racer from the '50s with a 46cm seat tube, but a 56cm top tube; this is no problem to ride given that I can stretch out enough with that size top tube; easy enough to go with slightly longer cranks (175-180 vice 170-172.5) and lift the saddle to adjust for height if your weight isn't too far forward (which is what it feels like on the Nishiki). Right now I feel a little "cramped" on the Nishiki even with the 58cm size, my reach still feels too long for the frame when I'm riding the horns; it has a 60mm stem, getting changed to a 110mm "Mutant" (adding 2") and should feel about the right reach (might go 90mm if too long, but no "Mutant" in that size).
I just bought another "Mutant" quill (used/ebay) for $35 in great condition; a great savings for me. If the Velosaloon site gives good shipping to your region, getting a reasonable price through them should not be too bad; maybe get you "NOS" around $60/65 Euro. I picked up a couple of frames from them recently so I was able to get a stem without added shipping. They had a nice Panasonic TT "funny" bike frame for sale (700c/26" I believe), a little pricey for me with shipping added, but still a great frame. They have some decent Gazelles in larger frame sizes, as well as some French/Vitus and Italian frames.
Putting the Moser "Leader" on the road (again) next weekend, should be interesting with the new set-up, first time riding with the "new" bar, stem, barcons, and brakes. I'm contemplating putting a 26" on the front just for "laughs"; see how it feels (it would look great, I think).
Take care,
Jesper
