Very very nice, I can understand the attention this is getting, rightfully that is.
And I dig mixing modern parts done with riding in mind, it makes the bike "alive". And I found upsweep is not just more comfy, it suits me for sharp steering in technical singletrack. I never really thought about it until I rode a straight bar in anger for a few weeks. Reverting back to bars with up/back sweep was an eye opener.
And I have to say it again, this is one smoooth build. It makes me really anticipate the Kona frame I just picked up on the Bay. And apologies for a small highjack, but is the seatpost in the '93 Explosif also 26.8mm?
TIA
