Brompton on the way to Aberdeen

Best Brompton Improvements

I’ve been riding my Brompton for about 7 years now, commuting to and from work about 25min each way. I’ve also done a few longer trips with it including a trip from London to Aberdeen, riding about 60 miles each day. So I think I’ve put some pretty serious mileage on it and have learnt a bit about what on it is good and what can be improved.

When I bought it, my Brompton was an M6L. That is it had the classic U shaped handlebars, 6 gears and lights and a rear rack. The lights were the bottle dynamo type, powered by a small wheel rubbing against the rear tyre and that was the first thing I got rid of. I didn’t really want the L type but I needed to get the bike in a bit of a rush (before the Scotland trip) and that was what was available at a reasonable price. The bottle dynamo is a waste of time, so much so that I think it has been discontinued. It would often flick on when going over a bump and seemed to make cycling a lot harder. LED lights are cheap and the batteries last a long time so they are a much better option.

Having said that, one good thing about the dynamo light is that the front light is mounted down near the wheel and is not obstructed by any luggage you might have. When using handlebar lights in conjunction with a large bag, the bag can obstruct the light, meaning that there is a shadow about 9 feet in front of you.

As mentioned above, LED lights are cheap so I have several on my bike. I keep a couple of Electron Backupz on for emergencies and as my main lights I have a Cateye Nanoshot on the front and the Moon Gem 3.0 on the back. Both of these are USB rechargeable which is essential for a commuter and the Nanoshot is bright enough to illuminate a dark road. I’ve had them for a couple of years and they are both great.

Another major improvement I’ve made is swapping out the basic foam grips for some Ergon GP3 grips. I cannot recommend these enough and Brompton should be offering them as an option. You have to cut them down to get them to fit (and it helps if you have the 2014 brake levers with the narrower bracket) but they will fit and not interfere with the fold, at least if you have the rack. They are incredibly comfortable and I can’t imagine going back to something else. On the trip to Scotland, my hands probably suffered more than anything and I wish I had had these then.

I was so impressed with the grips that I went back to Ergon for some pedals and got a pair of their PC2s. I only actually use the right pedal as I keep the folding one on the left but you can’t buy just one pedal… The main benefit of these is that they are flat – I found the standard Brompton pedal could tear up my shoe a fair bit, the problem is less on the folding pedal as the spindle area is larger.

This one might seem minor but has made a difference: a metal chain guard from Tiller Cycles. I was having issues with my plastic one coming loose, falling off and cracking so after seeing these on My Orange Brompton I bought one, and again it’s great. Makes the bike look better and I never worry about knocking it loose with my shoe.

Other changes I’ve made have mainly been to take advantage of the development that Brompton is doing. One of the best things about Brompton is that you can buy every individual part should you so wish so it is easy to upgrade and replace items. So over the years I have…

  • Swapped the standard tyres for Marathon plus on the back and Kojak on the front, then just Marathon plus on both as punctures are a real pain. The old Marathon plus seems to be better than the new one…
  • Upgraded the brake levers to the ones Brompton brought out in 2013-14. These are much much better
  • Upgraded the hub to the wide range version. To be honest I didn’t notice much difference with this and probably wouldn’t bother again. You don’t need as many gears as you think
  • When I got the new hub on, I had a new style rim put on as well. I’m pretty heavy and I kept breaking spokes on the rear wheel but since having the new rim (which is meant to have more sympathetic angles for the spokes) I haven’t had any problems
  • Replacement rear triangle when the bike shop spotted a crack in it, this Brompton replaced for free (credit to Simpsons Cycles¬†for spotting the issue)
  • Added the EZ wheels to the rear rack. Again these are much better than the standard ones

Bromptons are fantastic machines, but they can be improved. If you do one thing to yours put the Ergon grips on. It is very easy to do and a step change in comfort when cycling, especially if you are like me and have the seat above the level of the handlebars, resulting in a lot of weight going through your hands and wrists.

Coming up to Dundee I think – before I replaced the grips (or much else)
