Just Bought a Brompton, Need advice on Mods
Hi,
Just bought a Brompton T-5, and I need advice from other owners what mods they would suggest. It's stock, with 18% gear reduction, otherwise standard. Brakes? Grips? What about handlebars? Seats? I'm curious if there is a cheap fix for the poor braking. Any advice would be greatly appreciated.

Brooks grips to match the saddle.
Kool Stop salmon brake pads (levers are optional).
A Nashbar or Wald cruiser bar that is not as upright as the stock M-type bar.
Schwalbe Marathon tires.
Longer bolts for the hinge clamps.
Extra spokes, just in case.
Front carrier block.
Open basket for front carrier block.
You're looking at a few hundred $$$ in enhancements.

I have a T-5 and an L-3 and here's what I've done:
1) Upgraded the brakes to the current generation design; and most important is to replace the Brompton pads with the grippier compound from Kool-Stop;
2) Replaced the brake calipers with Shimano R-440's to get a sleeker look and more efficient lever action;
3) Replaced the steel seat post with the titanium seatpost - nice weight saving;
4) Replace the seat with the Brompton (Fizik) Vitesse and added the Penta Clip.
5) Added the carrier block and purchased the basket as well as the S type bag for a range of toting options.
I've kept the handlebars stock.
What I'm contemplating doing but no time soon is:
A) Replace the cranks and bottom bracket;
B) Remove the generator and carrier - I don't use them enougfh for the weight penalty they cause
c) Add the Pantour suspension hub for the front wheel - but still collecting information.

It all depends on what you want. I currently have my Brompton significantly heavier because I am using it daily without the need of folding or carrying it at all. Under this config., I have bar ends (that compromise the fold but gives me more cockpit room), Non-folding clipless pedals, front block with S-Type bag and fenders.
On August the 18th I will be traveling with the same bike: no fenders, no dar ends, no clipless pedals.
Now what I permanently changed:
Chainring, cranksets and BB;
carbon fiber bar;
salmon pads;
brake levers;
handgrips;
Extended seatpost, Thudbuster suspension and Specialized seat;
Upgraded rolling wheels.
What I am contemplating doing but no time soon is:
Add more gears (front derailleur with smaller ring);
buy a Brompton rear rack.

14R, why the dual suspension? What do you do for the front wheel?
Beautiful bike, by the way.

But I wasn't happy with the standard elastomer as my only source of anti-bumping. I assume I ended up used to most of the vibration coming from the front, but my internal organs were really feeling when I would jump something and land seated. I guess the fact that I had a thudbuster laying arround didn't hurt either.

I got a TSA 53T chainring, cheapest road bike crankarm and BBs available at the LBS. Not sure about the brand of the bbs. For a while, I tought I had the original one from Brompton.

All is needed is a tiny bit of filing (< 1mm) for it to fit in ze dropouts...
I know this 'cos I did it to the forks on my Brompton/Merc lightweight - (still to come out from garage as it awaits new rims and birdy rear elastomer)

Hi,
What exact model from Kool Stop is people using? I need to order them through my LBS, and this is the first time they see aq brompton, so I need to give them the exact specification.
Thanks,
Iago

I will be picking up an S2L pretty soon....this thread is great. Is there any reason NOT to replace the stock axles with quick-release axles so that flats can be more quickly fixed?

An old poster, wavshrdr, said he successfully used v-brake type salmon pads. I'm not sure which model though.

For the front wheel, you'll need to get the correct size quick-release in 74mm or make your own. You might also have issues with the clip, the part that attaches the front wheel to the chainstay when folded.
If you're really worried about flats, just use Marathons and be done with it. You probably are not racing this bike anyway.
