[monchito]

Hi everybody. My name is Jesús and I´m from Barcelona (Spain). I´m almost 38 but I ride since 11. I have to confess that i´m a WW almost from the begining, so I have broken a lot of parts of my bikes

I want to present you my bike, which i´m very proud. I hope you like it. It´s not so impressive as many others in this forum, but it´s mine and i love her.

Here it is:

And here parts of the process:

And here the seat in detail. If you press in some photo, you could go to a video where i show how flexy is the small part. (sorry, but i don´t know how to upload a video).
The thing is that the sit is very comfortable and pretty light.

This is part of the headset

And this is the "kind of veloplugs"


DSC02708 por monchito3000, en Flickr


DSC02711 por monchito3000, en Flickr


DSC02720 por monchito3000, en Flickr

I ride with this "veloplugs" for more than 12.000 Kmts an i had no problems.

This is a detail of front derailleur:

Here the brakes (I think still can save few grams. I´m sure that i can go to 210 grams without compromise of safety nor skills)


DSC02758 por monchito3000, en Flickr

This is one modified BB bearing, (from 42mm to 41mm Outside Diameter) and how i did:

I hope you had a nice time viewing this. I really would like to improve some things to next year. Some lighter wheels, some Schwolke handelbar, some Speedplay, some, some, some.....

Well first of all. You got a good looking bike there. I don't like the saddle, but thats nothing. Because you got some skills. It's always something special to watch this kind of work. Great tuning

[dereksmalls]

Very interesting work! Well done!

[NGMN]

A true Weight Weenie.

Nicely done.

[mellowJohnny]

Bro, this is fantastic! Don't say this bike it not as nice as some others on this forum - it is fabulous. A true, true weight weenie build. The amount of true tuning and customization makes this bike a one-of-a-kind. You made your own seat. You fabricated your own parts!

Chapeau, mon ami.

[hillrider]

I love youre "stumpy seatpost",very nice!! You should make and sell these to other Addict owners.

[robertg]

Wow, very impressive! Nice tuning work on everything. Nice way to drop grams everywhere. Your bike looks great and obviously is original.

[jmilliron]

Very WW! Love it.

[mrfish]

+1 Great work

[istigatrice]

Very Nice

[Tinea Pedis]

I hope you don't mind, I'm going to sticky this.

Fabulous tuning and work!

[artray]

Groovy . Red touches look first class.

This thread has been bookmarked!

[monchito]

Many thanks to everybody for your coments. They really caressed my ego and gave me positive energy enough to follow with some tuning this weekend. I really appreciate that you liked my bike and my work.

Here are a few fotos with more tech data:

This is the seat without the leather skin. It was a thin type (and delicate when rain) which weighed 12Grams.

And this is a part of the process. With this mold of wax I did a globe to give pressure inside the mold of the seat. I work with pressure instead of with void pump.


DSC01721(66) por monchito3000, en Flickr

And here i´m covering the wax mold with natural latex.


DSC01726 por monchito3000, en Flickr

This is the first BB bearings support inside the frame.


DSC02562 por monchito3000, en Flickr


DSC02572 por monchito3000, en Flickr

I changed it into these hoops of nylon...


DSC02573 por monchito3000, en Flickr

...with these strips of carbon between the hoops as reinforcement.


DSC02796 por monchito3000, en Flickr

These are some parts of the brakes:

Before...


DSC02451 por monchito3000, en Flickr

...and after


DSC02450 por monchito3000, en Flickr

Before... (already in aluminium, substituting the already heavy steel nut of the BR-7700 axel).


DSC02463 por monchito3000, en Flickr

...and after. It´s delrin. and i haven´t photo, but later, i did a little of drillium here too .


DSC02465 por monchito3000, en Flickr

This is my old bike (94-95). It has a lot of sick details. The frame (2.8 ) had some modifications and i painted and changed the fork. It was around 7.2 kg. Good weight for that time. The botle cage is not the original. The seat is a selle italia Sintesi, it was perfect for my ass, and that´s the reason why i used it to make the mold of the new one.
The true is that is not the most beautiful, but is comfortable.... and Aero


DSC04230 por monchito3000, en Flickr

And here, my love with a friend´s wheels. I think it looks even better than with the original ones.


DSC02842 (flickr) por monchito3000, en Flickr

And finally, the mold and the piece i´ll try to do this weekend.
