That sounds good, then i dont need the highspeed drive.

Not only do you save money, but it's better for your knees, your chain
and your sprockets, and probably overall cardiovascular fitness

Note that clipless pedals typically make high cadences much easier to
maintain.

Does a schlumpf highspeed drive strain bicycle parts? Or
did you mean that spinning faster eases the strain because
i then dont push so much force into the system?

Why is that? i figured that fastening the shoes to the
pedal would make it stay there in high spinning speed?

The latter.

Just like you say. Note that "clipless" means without clips and straps
and specifically refers to pedals you attack yourself to like SPD, Time
ATAC etc.

Okay, i thought you ment normal pedals that does not
have any means of having your foot stick to them.

One of the most confusing things about English bicycle terminology is
that one "clips" into "clipless" pedals.

For a bicycle like the HP Velotechnik Spirit I suggest considering a one
sided SPD/one sided platform pedal like the Shimano PD-M324:
<http://cycle.shimano-eu.com/catalog/cycle/products/component.jsp?PRODUCT%3C%3Eprd_id=845524441763012&FOLDER%3C%3Efolder_id=2534374302050115&ASSORTMENT%3C%3East_id=1408474395181667&bmUID=1200355335113>.
This will allow you to use normal shoes on short trips, and to clip in
with cycling shoes on longer rides.

Okay. I have already talked about that with the reseller,
and his opinion was that it was not needed, because the
foot already stayed nicely in the pedal. But maybe he doesnt
do longer trips.

The Spirit doesn't realy benefit from clipless the way a more laid-back
design like the Grasshopper does, just like the dealer says. But it
remains the case that on a longer trip a clipless pedal will be more
efficient and will also help you build to higher pedalling cadences.
You can also swap them across to your MTB to work on cadences there.

Taking both into account, I think Tom's suggestion of the one sided SPD
pedal is a very good one, so it's only there if you want it and "normal"
if you're just popping down to the shops or the like.

What about the Hase "heel-hangers", which provide a ledge on vhich the
shoe heel, and hence the whole foot, can be supported in position.

With high cadence it's not so much a matter of support, it's just easier
if you're attached as the aim is to "pedal in circles". A one-sided
SPuD pedal is just much less obtrusive, and will almost certainly be
cheaper, with no real downsides.

I have one of those one sided pedals, and it does work.

I lost a cleat and so had to pedal unclipped on that side for a bit.
Doable, but the difference in comfort, speed, and power was so obvious
that I don't bother using normal shoes on the bike.


My Shimano sandals work for me.

A compact like the Spirit will work a lot more acceptably with platforms
than anything more laid back (like most recumbents bar compacts), so I
probably wouldn't bother with changing my shoes for a couple of miles to
the shops and back on a bike like that, though I'd want them for
anything much longer.

> My Shimano sandals work for me.

Great aren't they? But I wish they'd stop "improving" them with extra
stuff on the uppers. My first pair were SD-55s, which had an extra
strip of side material on tghe upper added for the SD-60 for no obvious
reason, and now the SD=65 has got an extra strap for no real reason I
can see. The point of sandals seems to be less stuff == more air (and
thus comfort) around the feet, so why keep adding more? <sigh>
But even so, once it's warm enough they're really great things, and the
relative lack of upper means that Shimano's narrow last isn't a problem
for my wider feet.
