Montenegro Mfg.

Handmade bicycles, Carbon fiber repair and custom composites fabrication. Montenegro Manufacturing is a young bicycle composites company with a passion for great products of the best quality possible.

Every product is it's own piece of art. Art that is reliable, functional, light and fast!

With over 500 Carbon Fiber frames repaired in the last year, Hernan Montenegro earned the trust and loyalty from Bike shops, racers and avid cyclist all over the country. It's his expertise, close attention to detail and passion to keep his reputation strong that drives him to do better. Montenegro Manufacturing is a one man operation under the hands of Hernan Montenegro. Before starting Montenegro Manufacturing, Hernan discovered his trade while working under a local custom bicycle company, where he quickly moved up from assistant to head Composites Technician and Frame Builder, with main focus and expertise in Carbon Fiber Bicycle Frame repair. He has worked on all types of repairs: from small top tube cracks to bicycles broken in half, to repairs that other Carbon repair services have worked on and failed. He learned the mistakes that bicycle companies were making and where carbon fiber repair services were doing a poor job. Hernan made it up to him to change this; to make the product better and stronger than before; to allow the customer to depend on their bicycle again and enjoy it to the fullest. He’s constantly working on finding ways to make his products and services better by acquiring the best raw materials available and educating himself in the latest technologies in both the bicycle and composites world. Every job is meticulously performed by Hernan’s hands with sophistication and passion, to bring you the most reliable Carbon Fiber Bicycle Repair.

For some reason I can only post one photo at a time. Is this some sort of Instagram update or did I forget how to use Instagram?

This Saturday Oct. 3rd, our Rapha Clubhouses in Los Angeles and Chicago are hosting a celebration of their opening anniversaries. To highlight the community that has made the past years memorable, we’ve organized a Scavenger Hunt challenging riders to find city-edition water bottles hidden across town by the cyclists who have helped shape our Clubhouses. Each bottle contains a special token that can be redeemed at the Clubhouse for a prize. Riders will post locations of the hidden bottles to their instagram, and tag the journey using #LArideandseek / #CHIrideandseek. We’ve tagged all the riders below which will be posting clues. Follow them and keep an eye out for their clues Saturday Morning between 8 & 10am.

Sad Colnago Vs. Happy Colnago.


This road is near my house and it’s a shame I don’t ride it everyday. Conditions today were perfect. I’ll just stay at the shop later to accommodate for lost time. #worthit

This one is off the Tik Toks. Instagrams Reels will only let me share 15 second videos.

@richomundo’s MMFG Gravel bike also rips on the pavement.


Trust me, I rather be at work.


I think it’s about time I made this kit available to the public. Would you buy one?


I interrupt the regular bicycle related content with this custom carbon fiber steering wheel I made for a client. Just as a reminder that the MMFG services are not restricted to bicycle related fabrication or repairs but also anything that’s cool. Do you have an idea? Let’s make it happen! #customcarbon #carbonfiber #forgedcarbon

MMFG Enduro attack bars heading out to the east coast this week.


Hardtail XC frame I drew last night. Maybe I’ll make it. Maybe it’ll sit there till I draw something better. We’ll see, though I’ve been itching to make a Mountain bike for a long time now.


Getting accustomed to the new shop. We are now located on 2120 East 1st street. Open by appointment only for the time being.


Mailing out stickers this morning. #Bikesarenotcancelled stickers will be included for those who ordered stickers already. If you’d like a few of these stickers please send a couple bucks to @MontenegroMfg via Venmo. Appreciate your support!






Bikes are not Cancelled. Shop remains closed but I will be in for a couple hours today for drop offs set by appointment only. If you’d like to drop off your bike please e-mail me at [email protected]


While the financial world fall apart because of the pandemic, we are out here making the best of it. No Stock market, banks or airlines needed to enjoy a bike ride today!


Out here trying to get @tiktok famous. Though I must confess, I don’t really get it yet. Hopefully I can get the Gen Z demographic stoked on bikes.
