Bought one of the marley frames a little while back and have most of the parts I would need to build it 90 % new already put by for a previously planned upgrade of my current hardtail.
But I dont need or want a new bike right now as I am happy with what I have got, so it is safely boxed and filed until that situation changes, if it changes.
So could be built next year, 10 years or never.
My last build took 6 months to source all the parts and then built over a few evenings as at the time I had no knowledge or understanding of the process.
So googled the job in hand whether installing the chainset or fitting a deraileur, then did so once I understood what had to be done.
Some sites instruction was better explained than others but by far parks online guide was the best .
Step by step instruction that was easily grasped.
