Brompton pedals

I have MKS FD-6 folding pedals on my Downtube. http://harriscyclery.net/itemdetails.cfm?ID=660


Would it be worth replacing the standard Brompton pedals (including outer folding one) that are supplied as standard with the Brompton? Or, do people find the standard ones to be very good quality? I find them sturdy but prefer the look and fold of the of the MKS. However, the MKS grip can be slippy in wet conditions when first taking off on the bike.

Considered clipless? I found the brompton ones unbelievably slick and switched to SPDs after I almost fell off in front of a bus.

Hi,

first: late congrats to your bike - nice pics! I also don't like the looks of the brompton folding pedal that much, its narrow and it can hurt the frame if not carefully put together but they are said to be very durable.

On the 2008 model they finally put a little bump on the left crank to stop the pedal over-folding and massacring the top tube. However, you do still need to remember to unfold the pedal before the rest of the bike.

To be frank, stock brompton pedals are extremely poor, in functionality and weight. They are bulky, does not grip well (compared to modern CNC'ed pedals) and weigh A LOT (I've heard they weigh ~600grams)

If you don't mind using a non-foldable pedal, try to uses these small pedals (sold at $20-$40)

Or if you want MKS one, there are rubberized one that won't slip in wet conditions as well.

The design of the B folding pedal is somewhat over-engineered. I like the way the hinge makes the pedal swing beyond the crank as it makes for a far more compact state but I concur that it's ugly and heavy. Someone should work on a new version with SPD functionality and a little less bulk if you ask me.

A few pedal choices come to mind. I have Wellgo's on an old bike and they are pretty good.

1. Brompton (one folding/283g, other/135g) = 403g ... http://groups.yahoo.com/group/BromptonTalk/
2. MKS Promenade, 300g; metal, detachable not foldable ...http://www.mkspedal.com/
3. MKS FD-6, 428g: metal, folding
4. Wellgo FP-7, 426g; plastic, non slip, folding ... http://www.wellgo.com.tw/product.asp?category=folding

The Promenade scares me cause the sharp standing out cageparts. But the other Ezys look interesting:
XP Ezy 330g
AR-2 Ezy 340g
MT-E Ezy 370g
MM-cube Ezy 415g

Don't let yourself be limited just to Brompton parts-or any other make. I sure don't and my all my bikes are the better for it. Yes, you must limit yourself when it comes to the folding mechanisms ( hinges, levers, clamps, whatever) and special parts like the stems, handlebars, etc. that the bike has only to the manufacturer. But after the special part problem are address (and after all how often you replace these parts?-for me never!) then it is free choice throughout. Now I do admit some of the stuff Brompton offers are the greatest-like the special QR front luggage system-is superior to a dangling basket and that , might propel me to buy that special part(s) and wait a long time for delivery. But the other things-hardcase suitcase with DAHON, BROMPTON, BIKE FRIDAY, or the like screaming out the contents of that case contains (and opens up the possibility of theft)-I can safely pass on and find something far more cheaper and available here to use. The same with the pedals. Brompton's folding pedal is far better than a folding crank, but the pedal's weakness is the jutting out of that rather harsh even sharp part. I have no need to replace that pedal since I just use a clean old sock over the offending part. But some people might not like that solution and any pedal is up for grabs.

pd-A530

I use the PD-A530 Shimano pedals. One side clipless, one side "normal"pedal. Works great. Think they look much better than the original pedal and the frame ruining folding pedal...
Sure, no folding, so a bit bigger folding result, but a faster ride IMO...

Really like the FD-6's because

1) They fold and unfold beautifully. Really good Japanese production quality behind them.
2) They function well for me when pedalling and I'm 92 kilos (14.5 stone) and put a lot of pressure on pedals!
3) They look really cool.

Can anyone comment on whether the Brompton pedals are easy to fold? They're certainly the narrowest folding pedals and I might be able to overlook the weight if they're easy to fold:


Also, is there any source for a titanium right side bolt? Brompton only sells the titanium bolt for the left side. From what I gather they're about 250g per pedal IF the titanium bolt is used.

It is very easy and fast to fold. My 2009 Brompton has the new alloy right peddle and being the lightweight version has a alloy / titanium folding left peddle,

A folding pedal on the RH crank of a Brompton is not an advantage.

I know, but it'd be a huge advantage here:

Run the steel bolt or crank up your lathe. Make sure you use good tools, titanium is a female dog to machine.

Does anyone know the specs for the bolts?


Obviously the threaded portion is 9/16" diameter 20 threads per inch, but what is the diameter of the fat part, how long is it, and what's the diameter of the hex head?

Maybe I can find an aluminum replacement somewhere.

Aluminium is likely to fail at the base of the threads. There is a reason nobody uses aluminium pedal axles.

Given you've got to get a Brompton pedal anyway, wouldn't you just measure the supplied bolt?

Well I'm probably not going to machine a custom titanium bolt or run one side with steel (it would be imbalanced and the pedals are heavy enough as is).

The reason I'm considering the pedal upgrade now is because the next thing on my upgrade list is bottom bracket and cranks (just did kcnc front road brake with alligator i-link compressionless housing and carbon TT lever). I'd like to get some ultra-light short cranks, but that'll probably mean shortening some ultra-light "long" cranks.

I have an excellent hardware supplier in my city that only takes orders to specification that may be able to get the necessary bolt. Or I could get the cranks threaded to match whatever I can get. Or I can just forget about the Brompton pedals altogether. In any case it would be best to know what my options are before I start buying things.

Although I have to wonder, why does Brompton provide right side (steel) bolts at all when, as you mentioned, they provide no advantage on a Brompton?

Some people like to have matching pedals on a Brompton, even if it is a waste of money and weight.

You could bore a stepped hole down the centre of the steel bolt without losing significant strength, if it was done accurately.

Yeah, after a bit of research I was considering that that might actually be better because a lot of "standard" bicycle fittings seem to be odd sizes which predate industrial standardization and are basically obsolete outside the bicycle industry (so I might have a hard time finding an appropriate premanufactured bolt).

Also general opinion seems to be that the Brompton pedals are overbuilt and titanium bolts are weaker anyway and I believe either Leonard Rubin or Steve Parry used a similarly hollowed pedal axle. So it's not hard to believe that the titanium bolt is itself a bit of a gimmick just like the "titanium brompton" (no offense to Ti Brompton fans, but you'd probably save more weight with a tire swap). Plus this way I can try out the pedals until I'm done upgrading components and then go drill crazy on the whole bike.

While I have your eye, do you have any recommendation on the bore size/wall thickness?
