Brompton mods finally complete

First chance to take the bike for a spin today, having suffered from la grippe and le neige.

And here are the pictures:





Only cycled round the block, but the cycling position certainly feels less cramped and more upright. Not sure if the latter is a good thing, but I haven't adjusted anything yet.

Indeed, don't the handlebars get in the way of folding? When trying to mount something around the handlebars I usually found that it was getting in the way of the fold on the first try. The bike is extremely fine tuned around the fold.

This seems to be an S mast. When replacing the original Brompton S-bars on this you can go as high as ~10cm rise if you stay with the same width. If you go wider it will slightly limit the possible height. The S bar's grips are 924mm from the ground whereas the M has 1013mm and the P has even 1030mm overall height. The difference is what you can theoretically use for risers on the S before hitting the ground. I've been happily running a 8cm riserbar that was wider than stock on the S-model w/o issues until recently.

I have found, a la little pixel, a QR in lieu of that mast bolt is nice because you can adjust fore and aft rotation so easily.

QR is quick release. I have used one on my Brompton for years without a problem. Mine is just an old seatpost clamp.

Here is the bike folded:



The handlebar grips are a couple of millimeters off the ground, so no problem. Also adjusted the rake so the lug on the stem no longer touches the wheel nut. Only slight downside is the longer seat post means I have to remove the seat to fit the bike in the bike bag, but, as that only happens once or twice a year, it isn't a big deal.
