Desmondo,
Many people's dream frame-maker, with the pedigree of making Tour winning frames. A maker with innovative thinking and unmistakeable features.
I had a Marcelo for a couple of years - lovely bike, but, sacriligious to say, I preferred my carbon fibre bike, so sold it on.
How does your GGM ride? Pretty stiff drivetrain and solid feel to the front end, I imagine.
How long have you owned it, where did you buy it (direct from Italy?).
Are they Nucleon wheels (or Neutrons)?.
Regards,
David
