free Brompton workstand

does any one else do this? Lean your saddle back to the floor and you can fettle lots of stuff in the field

Yes, Very sensible method. It works for me.

Good idea...I like your double chain rings as well.

thanks still trying to spacer right for no chain rub on large sprocket only minor but still an irritant of inefficiency

I've got that problem - a wonky chainline when on the big ring.
I might just swap the chainrings over and have the big one on the inside. It'll look odd, but if you like things to look normal then perhaps a Brompton isn't the ideal starting position

I too had this problem with the 58 tooth on the inside and the 38 outside. Reversed this and no problems except I found it a bit nicer to change between rings with the smaller outside. It's been there so long I am not sure but I have a Shimano 118 BB. The crank is a 110 BCD with holes drilled for a 3rd chainring. Tried a 24 and it worked fine when pedalling but hit the rear triangle when folded so it went away. Bromptons are so much fun to tinker with!​

thanks for the idea will try the big outer small inner with same 4mm spacers between and let you know what happens .I prefer mechanical efficiency over visual beauty and when the two come together find myself with a warm smile

I didn't need any spacers but you might. I like the look of a second chain ring, and I like the look of me going up a grade without blowing out my ancient knees, having an aneurysm or a heart attack. I don't often use the little chain ring but when I do it's great to have it. Adds very little weight and paradoxically permits higher gearing since my 58 tooth chain ring isn't my only option.

Thanks! I normally flipped the B upside down, but that required doing something about the handlebars. This involves less nuisance and the bike that has a rack stays more stable.

its a stronglite 38 x50 on a 15 rear no more handlebar heave which I feel was bad for the man and bike

it keeps my old sram trigger shifter off the mud or pavement
