What too much time and a little jealousy will do to a man
In my case it has led to a sudden urge to build a parts bin weight weenie cycling vacation special.
Motivated by seeing mrs non-fixie enjoying her little red RIH, I decided I too needed a sub-10kg bike for our next vacation trip (whenever that may be). I didn't want to spend any money before being reasonably sure I was onto something, so for now I made do with what I had available: a scruffy Reynolds 531 frame with eyelets and room for fenders, Birmalux seatpost, CLB brakes and levers, Suntour Cyclone derailleurs, Bluemels mudguards, Stronglight cranks. According to my cheap luggage scales it weighs exactly 10kg as pictured, which is a full kg lighter than any of my other 25" fendered bikes. I just took it for a short test ride, and it feels rather nice. Light and responsive, without any of the nervousness I was half expecting. It corners beautifully. That narrow saddle needs to go, though. https://cimg8.ibsrv.net/gimg/bikefor...7d7828e91d.jpg The CLB brakes are a nice surprise. They are very light, but feel quite solid and the braking compares favorably to the MAFAC's I am used to. https://cimg6.ibsrv.net/gimg/bikefor...209974bb2a.jpg The levers feel nice too, even without hoods. https://cimg5.ibsrv.net/gimg/bikefor...364d64f733.jpg There is still some work to do. To be able to add a bottle cage, bar tape and swap the too narrow Arius for a comfy Brooks I need to shave off at least another 200g ... |
Ten kilos for 25" frame with pedals & fenders is tough even with light wheels, in my experience. ;)
I say = Well Done! :thumb: i will search Jonkers. For their lightweight large frames. |
Fun project!
I love blue bikes. Yours is handsome, practical fun. FWIW I would be really tempted to go with a bar like a MAP/Ahearne to sit in an upright position. Fun for sightseeing on vacation. :) |
I’d put a unicantor CMX on that build, weighs nothing and surprisingly comfy, you know, like, for my butt anyway. :D

I think it had something to do with the short wheelbase bikes like these tend to have.

Even with all the nice stuff I have, I'd be pretty proud to have a "scruffy" frame like that gathering dust! Really nice, clean and classy build.
Also, you've learned the great secret of CLB brakes. Their weight is measured in negative grams. -Kurt |
This lockdown has everybody building. Great looking bike!
|
I think that turned out rather splendidly! I certainly would have guessed that it came out at 10.5-11kg at best given the size of the frame, use of fenders, and what appears to be a rather average wheel set. However, you didn't mention particulars about the wheels and tires yet, and that could amount to a large part of the weight savings... More details would be appreciated!

10kg - that's about 9 pounds - right?
Great looking bike! Love retrofriction. |
to lose 200gms, lightweight tubular rims with racing silks not wider than 20mm.
the caveat is: ... weight weenie successes may detract from one's touring vacation enjoyment. unless one's spouse is tough at the pace and pushing one's limits. sometimes, a really good man knows his weaknesses - and is cunning enough to work around them - invisibly, but to the most discerning. |
I am totally diggin it! Nice

Man! My weeniest bike is a little over 10kg and only a 59cm. And not even thinking about having fenders. Nice build! :thumb:

Really nice, your parts bin build is looking like your bin is on the top shelf. I have a set of those CLB brakes but in red font. The cane creek hoods fit fine on the levers. I hear one of the kool stop pad insert styles can also fit into the CLB pad holders but I dont know which one.

Great looking bike! Love retrofriction. I love the retrofrictions too, but they weigh 72 grams, which equals about 5 pounds, so they may have to go. :(

You did an amazing job, but good lord, what's the head tube angle on that? 75? 76?

Bit of a disappointing day, today.
Got me a new battery for some digital scales, with the objective to get a more detailed weight measurement, so I could see every 10g saving from now on. :) Weighed the bike with these, and was told is was 10.45 kg. :( So, I exchanged the wheels for a pair I had prepared for an upcoming build for mrs non-fixie (Campagnolo low flange hubs, Mavic rims, radially laced front wheel) and now I am "back" to an indicated 10.05 kg. Phew. I need to find some more weight savings elsewhere ... |

Saddle and pedals look to be about the only remaining opportunities.
riding without a saddle is tough; but how so - without pedals??? :foo: |
It's beautiful.
I notice taller frames can have a steeper head tube. |
That is a real beauty and in my size, too.

What seatpost do you have on there? American Classic posts can be had from Ebay for short money in many different sizes, and weigh under 175g. None of mine have broken ...yet.
