Magnesium Pedals - Wow!

Pedal weight is probably one of the most intrusive areas for weight on a
unicycle. You have your rolling mass, which includes the wheel and
crankset. Whatever rolls has to be accelerated/decelerated for each
correction in balance or change of speed/direction. Then you have the
off-putting weight of the cranks and pedals; the things that make your
wheel want to wobble (not including your legs). The heavier they are
the more your wheel will tend to weave side to side, or the more you
have to resist against it. In this area the pedals are the main
culprits, and your Iron Cross pedals are notoriously heavy, are they
not?

So of course you'd feel a major difference by switching from very heavy
to very light pedals. Especially on something like a commuter unicycle.

So I guess I'd say changing pedal weight is one of the most obvious
ways to make your unicycle feel and ride lighter. Pedals, tire, cranks,
rim. Those are the main ones.

Iron pedals were actually meant for crusading knights wearing chain
mail, not unicyclists !🙂
Anyway, that is an interesting observation. Here's an idea for you,
why not put one heavy pedal back on, just to see how weird it is ? How
different each side feels, if at all.

Dan's cycle shows the Iron pedals at 31 oz.
http://www.danscomp.com/465120.php?cat=PARTS
31 x 28.35 = 878 grams
The mags are 375 grams
You took almost a pound off your uni weight, compared to running the
welgo mags !:eek:
Of course you can feel the light 😄 LOL You'll be safer to if it
ever falls on you😄

So then would good quality *plastic* pedals be best for
_commuting_on_a_coker_? Since you're not doing anything extreme (unless
coker muni) and riding mostly on flat, smooth bike path, I'm wondering
now if plastic or at least Magnesium pedals would be best. thoughts?

They were OK with 6 " cranks, kinda slippery on 5's. I just switched
them to my muni the other day to try the snafus on the 36.
I'm going to go try the 24 with them now for the first time. Riding
time !🙂

As long as they grip and won't break, there's no reason to avoid
plastic. Unlike metal pedals with screwed-in pins, plastic pedals
generally go dull after a while, so this is a factor. But plastic
pedals are usually required on the track for racing, so you have to
find some plastic pedals with grip you can live with. This is where the
turf shoes come in handy. Together with a decent plastic pedal, you
still have a nice good grip.

What do you use on your coker? VIvalargo uses Azonic magnesium pedals;
light, grippy and inexpensive. http://tinyurl.com/3xaw5o

I use Drilliums on my main Muni and mag. Azonics on my 29er, and some
otheer mag pedals on my Coker. I think for Cokering, the cheapest and
lightest pedals you can get are the ticket. Google mag. DH bike pedals
and you'll get plenty of results. You can often find the Azonic mags
for 20-something bucks, which is a great deal (if they don't shaft you
on the shipping). But I haven't bought pedals in over a year so maybe
that's changed.

I just found a local place (Pricepoint.com) in Gardena. They have those
azonics mags for about $30 out the door! Picking them up tomorrow, sans
shipping charge! Hey, I found these on UDC,
http://www.unicycle.com/shopping/shopexd.asp?id=726
they say they weigh only 12.7 oz! But is that *per* pedal, or for the
whole pair. The azonice mags are just over 1 pound for the pair.

*edit* From what I could gather on google, that is _PER_PEDAL_! UDC's
ad is a bit misleading and should state that it is *per* pedal, because
it implies 12.7 oz is for the whole pair!

I always avoid metal pedals on commuter unis, just because I hate riding
metal pedals without shinguards. They're also not so great in crowds.
The $11 Odysseys are fine in plastic.

The Wellgo magnesiums are nice until they disintegrate on you in the
middle of a ride. I was lucky--they disintegrated on me at the
beginning of a ride.

"disintegrated" How would that happen, and is magnesium more likely to
fall apart than plastic?

It's not because they're magnesium, it's because they're Wellgo
sealed-bearing pedals. They have a really cheesy retaining clip as the
only thing that's holding the pedal on the axle, and eventually it
fails and the pedal falls apart. Walk home, or ride on the spindle.

I noticed that acceleration and general feel was faster feeling.🙂 I
had swapped out the 694+70 gr. bumpers Snafus for these plastics
http://www.unicycle.com/shopping/shopexd.asp?id=216
that weigh maybe I'll guess 400 gr. It wasn't night and day, but it
was a real improvement. I was kind of scared of the plastics on the 36
because I ride real far and I don't want to be stuck in the rain on
those slippery plastics.:eek:
I'll replace the plastics on the muni soon, but for 10 $ I think
they make great spares.🙂

Those pedals are just about the lightest metal platform pedals you can
get. I've thought of getting them myself.

I switched my 170 cranks back to the stock 150's and kept the Primo
pedals I had on my DX. It was horrible, not at all like I remembered.
There was no control, just simple riding felt like I was going to UPD
at any moment. The Primos are very heavy (600 g./pair), thick, not
very concave and the pins don't provide much grip (up to now they have
been fine on dry roads w/ the 170's and on my 20). So I switched to my
Kona's (about 500 g. and better at all the above). I was similarly
shocked. I couldn't believe changing pedals could make such a huge
difference. I now had heaps of control. They are a bit too grippy for
dry roads so I took out a few of the pins.

I've tried to ride w/ plastic pedals and I can't keep my feet on
them😠

I would think pedal protectors would delay that significantly. I have
them on all of my pedals. Stock DX, Primo pro aluminum, JC's, 'KONA '
(http://tinyurl.com/2elvas)sealed. My favorites are the Kona's.

It may not just be the weight of the DK Iron Cross pedals that is
causing the difference in feel. I find thick pedals (like the DK Iron
Cross) to be less ideal for a road unicycle (where you're spinning the
pedals) than thinner pedals. So the difference could also be in the
thickness of the pedals. The magnesium pedals are thinner than the DK
Iron Cross pedals. The Wellgo pedals are going to feel better
regardless of weight.

Someone mentioned the 'Gusset Slim Jim' (http://tinyurl.com/2sbny9)
pedal, and they're ridiculously light as well (425g)

However, with all the horror stories about Wellgo's
disintegrating...I'm wondering is this a common problem for sealed
pedals in general, or is it specifically the Wellgos that are crappy in
this aspect? I'd be surprised, cause Wellgo is a big pedal company...
