GT Mach One. 1985

This bike is a gift to me from former 80´s BMX racer Jesper Rosling. I got it from him in early 2014. He bought it brand new at TWS (Two Wheel Service) BMX shop in Märsta in 1985. Jesper stopped riding BMX in 1985, but started again in late 2013. He is most known for his motocross and quadracer skills.

When Jesper bought the bike brand new, he traded the original wheels to a white set of ACS Mike Buff Z-rims instead, and he also bought a GT padset in chrome which he couldn’t find now. I was lucky to find a new reproduction set of chrome GT pads.

The bike was missing some parts when I got it, but I have tried to build it like Jesper used to have it, and some parts like the factory stock equipped bike. I already had the correct handlebar, seat post clamp and seat post for it.

The black GT skinwall tires with the GT-logo-tread is very hard to find. I was able to find a set with good tread, but the rubber/sidewalls is very dry and won’t be good for riding.

I bought the reproduction GT Mach One frame & fork decals from Frog in France, but I will never order anything from him in the future. It took him 2,5 months to send the decals. Beware of him! 🙁

Many thanks to Jesper for donating the bike to me! 🙂

    stedet ffor avanserte funkjoner ser det ut til
    at mange foretrekker en enkeel oppbygning.

    Dette gjør spillopplevelsen mer behagelig, spesielt for de som spiller mer av og
    til. Fokus ligger ofte på den generelle påliteligheten fremfor store kampanjer.

    Personlig virker det som realistiske forventninger er
    viktig. Når man ikke overdriver, kan casino i Norge oppleves
    som en balansert løsning. https://biglucky-norwey.com/

    Op basis van mijn ervaring, voelt spelen in een casino waar met echt geld
    wordt gespeeld duidelijk anders dan gratis spellen. Zodra er echtt
    geld bij komt kijken, gaan mensen meestal langzaamer beslissingen nemen.

    Veeel gebruikers benaderen dit soort casino’s
    niet allern om te winnen, maar ook om de spellen beter te begrijpen. Zaken zoals staiele werking lijken belangrijker
    ddan opvallende functies oof grote beloftes.

    Vanuit gebruikersperspectief, hangt de ervaring sterk
    af van zelfbeheersing. Wanneer iemand niet overhaast
    speelt, kan een cassino met echt gekd een evenwichjtige ervaring bieden. Uiteindelijk draait het vooral om dee juiste mindset. https://sunnyhomecenter.com/gratis-spinza-speelhal-uw-plaats-voor-4/

    Et casino med umiddelbar uttak fokuserwr på effektiv behandling.
    Etter at uttak er bekreftet, settes prosessen i gang automatisk.
    Autommatiserte kontroller bidrdar til minimal behandlingstid.
    Samtidig som tempo prioriteres, er teknologisk pålitelighet avgjørende.
    Som et resultat skapes en sømløs opplevelse for et bredt
    publikum.

    You actually make it seem so easy with your presentation but
    I find this topic to be really something which I think I would never
    understand. It seems too complicated and extremely broad for me.

    I’m looking forward for your next post, I’ll try to get the hang of it! https://tonybets.ie/

    Have you ever thought about adding a little bit more than just
    your articles? I mean, what you say is important and everything.
    Nevertheless think about if you added some great photos or videos to give your posts more,
    “pop”! Your content is excellent but with images and video clips,
    this website could definitely be one of the greatest in its niche.
    Terrific blog! https://02BET.Es/

    Amazing blog! Do you have any hints for aspiring writers?
    I’m hoping to start my own blog soon but I’m a little lost on everything.
    Would you propose starting with a free platform
    like WordPress or go for a paid option? There are so many choices out there that I’m completely overwhelmed ..
    Any suggestions? Cheers! https://tonybet.eu.com

    Hello, I think your website might be having browser compatibility issues.
    When I look at your website in Chrome, it looks fine but when opening
    in Internet Explorer, it has some overlapping.
    I just wanted to give you a quick heads up! Other then that,
    fantastic blog! https://tonybets.com.es/

    Hi would you mind stating which blog platform you’re working with?
    I’m going to start my own blog in the near future but I’m having
    a hard time deciding between BlogEngine/Wordpress/B2evolution and Drupal.
    The reason I ask is because your design seems different then most blogs
    and I’m looking for something unique.
    P.S My apologies for getting off-topic but I had to ask! https://20-Bet.de

    Hey there! I just wanted to ask if you ever have any problems with hackers?
    My last blog (wordpress) was hacked and I ended up losing several weeks of hard work due to no data backup.
    Do you have any solutions to stop hackers? https://Betlabelspain.com/
