Libretas Mixtie, Jump On it at $250?
 

Sadly I ,missed out on this, it sold, for 175 andI guess the shipping too on the 14th :cry: Now I've having palpitations and vasilations over the Soma sale :twitchy:


I've been thinking about a Mixtie for some time and would love a nice frame to move my IGH wheelset to. I just happen to stumble on this on the 'bay this morining but I'm not too familiar with the name. Is Libertas a good name?

$175 BIN and $78 shipping. For comparison a 58 SOma is $700 with a Tange frame. https://www.ebay.com/itm/28555392581...Bk9SR57l6eX3Yg

531 and 60cm C to T seat tube and 58 C t C top tube. Are the dropouts for Simplex or CampI? (I think Simplex is that type RD hard to find?) not that it matters as I'd like to use this for IGH wheels.

since it is a Flanderlandt produkt it will be BSC so no worries about sourcing metric bits for the build...

ends set is a Juy model which launched 1973-74

hope it works out for you so we will all be able to enjoy the build textilium ;)

mixte this large are not common

Thanks for "textilium"! (Adjectival form: textilis, woven, plaited, knitted.)

Surprising how seldom Liberia bikes show up in C&V. Or maybe not: I remember seeing a few around in the '70s, but not since.

Trakhak Liberia? Stupid AI :lol: Yeah I think I think I saw a few years ago when I first started comeing here but not many recently.

Really nice frame and high end mixte's this size are pretty rare. Not a great price but within reason if it's something you really want and your not likely to come across another mixte frame set of this size and quality any time soon. Libertas made quit a few nice large step through bikes so not super rare just most were sold in Europe so it is pretty rare for one to pop up in this condition in the US as frame set. I think this bike would build up very nicely with IGH. I don't see any issues with the build your planning for it.

I found this, barely readable, '76 spec sheet on the Cabe. The color isn't right but I'm guessing it's with a year or two of this. Super Course MKII. I used a magnifying glass help up to my desktop screen.

:foo:

why are you posting a Sir Wally specifications cross table in a discussion thread about a Libertas frameset?


-----

Because I didn't realize the spec sheet was for comparing the OP's Librertas to the similar Raleigh, I thought it was the Libertas catalog https://thecabe.com/forum/threads/pl...bertas.127513/

@bianchigirl Not knowledgeable to comment on this bike, but I will say I have been on the look out for good quality large mixte's since you made posts saying you were looking. Notice I haven't really posted any and I am in a pretty big bike market. They do seem rare.

That's a fine looking bike. I have a 531 Libertas in the build queue and it looks to be a well built bicycle. Agree with the others, given how difficult it is to find a taller higher end mixte, the price is reasonable. Plus this frame looks to be in great shape. Looking forward to the build thread.

@Bianchigirll,
If you do decide on external gears I have the bits here to make changes and a couple of Huret Eco-Duopars that will fit it. I sure hope you get it! It should be a fun one. Smiles, MH

minor build tip -

in case you elect to proceed one thing to check upon arrival is shell width

there are some Flemische products constructed to BSC standard which are built with seventy mm shells

this combination eliminates the possibility of using a SPECTA or Verot BB assembly as neither maker fabricated spindles for shells of that width

they accommodated Italian shells by making the walls of Italian dimension cups one mm thicker than those of BSC & metric cups

I am not a big fan of the brand, mostly I think of their stuff as boom time. This mixtie appears better than most Libertas period. I lean more to the yes than no. The derailleur hanger is the only real perceived drawback.

This is the tallest mixte I’ve ever seen . I will admit , I don’t pay much attention to them because they all seem to be way small for me to enjoy. They seem like they would be handy to ride for city riding or running errands. My daughter had a mixte and she rode it quite a bit . I have it stored in my shed in case she gets interested in riding it again.

Bianchigirll FWIW: I have the disc brake version of the Soma Buena Vista. Their price has come down from the pandemic high of ~$1000 that I paid. So, I would call $700 a good buy if you were on the fence with the idea.

For mine, I ditched the OEM fork & built it up with a pile of weight-weenie road components I had on hand from other projects. It came out to 19 pounds and a few ounces. All in, owing to materials already on hand, the whole project probably set back my lifetime earnings about $2k over not having ventured at all. Very much worth it. It is a supremely well riding and sporty road bike.

My only gripe is that as a bolder than average descender the torsional stiffness does not inspire confidence in negotiating switchbacks at inappropriately high speed. Wide low pressure tires 700x38 slick tires hold the road well, but if only the feedback were less vague between where the front wheel was pointed and the saddle and back wheel followed...

I suppose that characteristic is inherent any and all mixte designs and due to the triangulation between the rear dropouts and the head tube they are a whole mess better than any other low/mid-step design. The mixte is the clear choice for better roadier road bike performance among non-diamond frame designs. (They're just harder to manufacture, thus less common.)

If I were to do it again, (knowing that torsional stiffness is it's only weak spot, (If you are really pushing it)) I'd spec a larger headtube and downtube than the good folks at Soma. For a point of reference, I had a diamond frame Ritchey Ascent that I paid double for & it felt mushy and vague all the time!

All this is to say: "Don't let the $700 price tag scare you. The Buena Vista is a very fine riding bicycle."

I do wish I had input on the Libretas. It is a pretty blue color. What I can't say is whether or not it conforms to any modern "standard." It'd be a shame to spend $250 only to find out there is an Achilles heel with some component made of unobtanium. This is purely my own ignorance that makes me wary. At least the Soma is a known known.

One thing I like about this frame not noted earlier is the way the rear triangle is done should allow for a bit more wiggle room for spacing for different gearing setups and clearance for wider tires and possibly fenders which gives you more build choices options. I think this one would be great with IGH setup with fenders and rear rack for around town city bike that is a notch or two above most of the stuff out there.

base2 Yeah I've been looking the Buena Vists for a long time. I don't undersrtand why they don't set up the disc brake frame to be ambidextrous, not that I want disc but I think ithe resale value would be better. Also the vertical dropouts mean I'd need a tensioner for the IGH set up

Bianchigirll The dropouts are sliding so that even though they are vertical, the IS mount disc, axle, "everything" can be adjusted for chain tension.

Also, the sliding axle plates can be replaced. There are through-axle options in both flat and post mount. https://www.merrysales.com/shop?&search=sliding


But, yeah. A single ambidexterous frame with a brake bridge drilled that could accept a long reach calper like a Tektro 599 doesn't seem like it would be impossible to do. I wonder what their thinking was.

BG, that looks like a Simplex type derailleur hanger without the stop for a Campy/Suntour rd ... if that's meaningful to you.

SurferRosa Yeah I wasn't too sure about that, it's hard to get a good look in that pics, not sure if that accidental or by design. Again I'm thinking of this for my IGH wheels so unless I need a tensioner I shouldn't need the hanger.

base2 Yeah but they didn't set it to use a rim brake in the rear for some reason. perhaps because the adjustable dropouts?

https://cimg0.ibsrv.net/gimg/bikefor...c802d22bc8.jpg

The rim brake model has horizontal drop outs and the brake bridge that is omitted on the disc version. I was agreeing that it is a shame they didn't include the bridge and have a single frame that could accomodate both types. Probably production cost related somehow. 😞

What kind of IGH do you have? If Shimano there is a strong chance that there may be a rubber cover over a centerlock disc mount or a fitting for a roller brake. There is a company that makes a rollerbrake to disc adaptor.

@base2 Alfine 8spd redstripe (go beer!) yes both the rear and dynamo front have the threading for disc but I have no intrest in them

one seldom encountered bit of metal worn by the frame is the ESGE laterals bridge

usually the very lowest bicycles will just use a piece of strap steel for a laterals bridge

nicer frames will employ an attractively designed piece from a maker such as BOCAMA or NERVEX

​​​​​​https://i.ebayimg.com/images/g/PHkAA...4h/s-l1600.jpg

here is a catalogue page illustrating two BOCAMA designs

https://cimg8.ibsrv.net/gimg/bikefor...b001898989.jpg

suspect the BOCAMA & NERVEX bridges may have been unusable here due to the angle made between the seat tube and the laterals


-----

Quality tubing and chromed lugs, that is is the best mixte frame I have seen.

That frame looks a treat. As others have said, the ride may lack rigidity and in its place you will find a springiness that is actually fun when you get used to it. But I wouldn't charge too hard into corners.

Looking forward to the build if you end up pulling the trigger.
