odd frame measurements

Hi

Not content with buggering up my original bike, I've noticed a couple
of frames on ebay that I could play around with:

Link not valid for the first one - looks like it way already have been
sold. The Peugeot 653 looks like a very nice frame, though. Some chips
and scratches in the paint, as the seller freely admits, but the chrome
plating is in excellent nick, which is a good sign.

Thanks - as an ex-Quasar owner (apparently there used to be problems
with the ovalised frame tubes cracking, but mine seemed to have escaped
this), I'll give it a go.

Given that my Record Sprint now boasts a Camagnolo Record front mech
(bought very cheap on ebay), I have an original Sachs Huret front mech
in the parts bin, well used but not bent. Would you like it?

Nice! Note that it will be built for 27" wheels, so if you use 700c
wheels you'll need 'deep drop' brakes. You would also need to cold-set
the back end to take a modern back wheel.

Taking how to measure the tube Sizes from here,

I get:

Top tube: c-c 56.5 cm
Seat tube: c-c 58 cm and c-t 59.3 cm

That's a 23" frame.

Firstly, I expected the seat tube c-c to be more like 53/54 cm. 58 cm

The expected 53/54 for the seat tube would fit in quite nicely with
these pairs of values.

Yup, same on my Record Sprint. 63cm seat tube (c-c), 57cm top tube
(c-c). My (new) Dolan is 60cm seat tube, 60 cm top tube. Fashions in
bike geometry have changed, of course, but I think the truth is the
Record Sprint was never meant to be a racing bike, it was meant to be a
bike which _looked_ like a racing bike but with a compromise riding
position which leisure riders would be more comfortable in.

Why are you convinced that you have a 21" frame?

Raleigh sizes generally measure from the centre of the bottom bracket shell
to the top of the seat lug. Yours is almost certainly a 23 1/2" frame. The
top tube length sounds correct. I used to own a 23 1/2" Record Sprint.

Quoted message said:

That's not unusual. The fashion for lower handlebars and longer seatposts
has led to longer top tubes relative to seat tube length, but at the time
your Record Sprint was made, shorter top tubes were the norm, particularly
in the larger sizes. It wasn't uncommon for makers to keep the same top
tube length throughout the size range, meaning that smaller frames had
relatively longer top tubes.

Strange, if you copy the link out and paste it into a browser, they're
both OK. But both fail for me if I just click on the hyperlink.

The first one (that doesn't work) is a "Classic Reynolds 531 road frame
49 cm c-c campagnolo".

Btw, using the Zinn book's measuring method using inside leg, torso and
arm length I get:

seat tube - 49/50 cm
top tube - 56 cm
handlebar stem - 12 cm
crankarm - 167.5 mm

So, if say, I was to buy the 49 seat tube, 52 top tube frame, would a
sensible 'correction' be to buy a longer stem handlebar?

Of course, it's all down to on-bike tuning but wondering if this would
be feasible as a starting point?

That's true - thanks for reminding me - people seem to think those
Shimano RSX100 ones are pretty good but I'll just have a fish around
anyway. Luckily my Record Sprint was for 700c so I got away with
'modern' reach brakes but do have to cold-set the frame: it's my new
hobby!

Weird. It was a long, long time ago but I was convinced that I had a
19" Winner then a 21" Sprint which is why I thought something odd was
going on as there didn't seem to be a 23" frame on the brochure link.

That all makes sense and I did notice that most of the modern road
bikes had very similar seat tube and top tube dimensions. Poor old
Record Sprint: it's more like a sit-up-and-beg especially with my
saddle position!

Cheers for help,

I'm not anymore, but I've spent 18 years thinking it was a 21" frame! I
can't believe I was sold a 23.5" frame back then but it definitely is.
Anyway, it was so I could grow into it (very optimistic)!

Cheers for that bit of history: it's quite interesting to see how road
bikes have changed. I was only comparing the values I obtained with
modern-day information + the dimensions on the ebay frames. When you
look at the Record Sprint, as someone else has said, it's not really
supposed to have road-bike geometry as such, just look a bit like one
for a birthday or Christmas present :-)

That's not really true. Certainly, the Sprint wasn't an out-and-out road
racing bike, but it had features in common with bikes that would have been
ridden in club-level competitions at the time, and the geometry was sporty.
Compare the angles and clearances of the Sprint with the contemporary
Record Ace and Road Ace, or even the Team Replica. The Sprint was a sports
bike. Yours is simply much too big for you. I'm 6'1", and found my 23 1/2"
Sprint a good fit.

You can do quite a lot of 'length' tuning with saddle position and stem
length - and it's amazing how much difference just a centimetre on the
stem can make to your comfort.

I note that (contra my precious post) the bike is said to be 700c, but
that strikes me as odd for a UK built bike from the eighties. If it is
700c so much the better but don't be surprised if it isn't.

It wasn't that unusual for sportier bikes from the fifties onwards to be
designed for 700c or dual (700c/27"😉 use. All tub rims were 700c, and it
was common to use tubs for racing and clinchers (700c or 27"😉 for training
and social rides, swapping wheels as required.

One day-ish left on the auction for these lovely frames. I keep on
deliberating which one to go for!

If it was down to looks I'd go for the Tom Avon:
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=7119093437 and
it's 49/52.

The calcs provide 49/56 as suitable for me (well, I am a bit wonky
shaped).

The Peugeot (
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=7118344114 ) is
slightly bigger: 52/54 but could easily manage the frame size given
that I've been on a 23 1/2" frame! Comes with seat post too.

Quoted message said:

From what I've read the top tube is the most crucial measurement so,

just in terms of dimensions of the two vs my size, is there much
between the two? I don't know how much a difference 2 cms makes!

Well, I'm talking to myself a bit here :-) but the two auctions have
finished.

The 531 http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=7119093437
went for over £220! It was extremely sought-after but I couldn't
really compete at that price. I wonder if that was a fair price?

The 653 http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=7118344114
went for just over £100 and I won it, so I'll be whizzing around on
that next year hopefully! Not sure if it was a bargain or not but it
seem to be in good condition and was affordable.
Cheers for all the help and comments regarding my current frame.
