We all are.....See quite a few in Londonium...What's quite scary is when one of the buggers is faster than me.

Dealing with tiny wheels and an 11t top sprocket. Causes huge issues so building a freewheel that goes to a 9t then i can put a 61/46 combo on the front and solve a huge pile of problems..Love the green and white. What is the purpose of that large chain ring?
I have a Tern too, it folds down to the size of a bicycleBlimey this is turning into a show us your Brompton thread!
In the interests of balance, here's a pic of my Tern Link Uno just after I purchased it in 2015. After daily commuting service for three years it's looking a little scruffier now, but I don't have a more recent photo. It's been an ultra reliable commuter bike and rides really well View attachment 426848 .
Please excuse my lack of knowledge on the subject, but does that mean a higher gear for more speed?Dealing with tiny wheels and an 11t top sprocket. Causes huge issues so building a freewheel that goes to a 9t then i can put a 61/46 combo on the front and solve a huge pile of problems..
Brompton to the rescue.
Just to redress the balance.Bought August 2014.Used yesterday when fixie developed another p*nct*re...although managed to get back.Called Brompton into service to pick up package.
That pic is a bit bloody small.
Yeah, kind of... the biggest ring you can fit to a Brompton without folding issues is around 60 teeth, the smallest rear sprocket generally available for the wheels i have fitted is a 11, with racing tyres thats less than 80 gear inches in top and i cannot spin my legs over at a decent speed... the 75t ring solves that, but causes problems all over the place of its own. By building a freewheel that goes to a 9t top sprocket I can then swap out that chainset and its overwidth bottom bracket solving issues of chain retention and folding in one go. Other mods needed are to move the rear brake mounting to get the Delta repositioned to not hit the ground when folded and use a stronger setup on the handlebar swivel.Please excuse my lack of knowledge on the subject, but does that mean a higher gear for more speed?
Poor Brommie Well, once in a while in the winter I might drive up to Flagstaff and have a butchers.One for @Rockn Robin in Arizona - not sure if you know what this white stuff is?

I assume the combination that you decided on works out well for you. Quite a science behind that.Yeah, kind of... the biggest ring you can fit to a Brompton without folding issues is around 60 teeth, the smallest rear sprocket generally available for the wheels i have fitted is a 11, with racing tyres thats less than 80 gear inches in top and i cannot spin my legs over at a decent speed... the 75t ring solves that, but causes problems all over the place of its own.

Thank you for adding some diversity.Blimey this is turning into a show us your Brompton thread!
