Translations for some bicycle-related words

Hello,

I'm doing a translation as a favor to a friend for an article about a bike and am unfamiliar with a few terms that I also couldn't find on translation dictionaries. If any of you are bike experts, I'd be very happy for your help:

Montagefertig
Lenkungslager
Schellen (Sattelklemmschelle)
Wiegetritt
Lenkkopf
Seitensteifigkeit
Lagerspiel
Streben (Sitzstreben/Kettenstreben)
Schlauchreifen vs. Drahtreifen

I'd appreciate any help at all.. thank you

Moi

Montagefertig Ready assembled
Lenkungslager Headset bearing
Schellen (Sattelklemmschelle) Clamp/clip (Saddleclamp or clip)
Wiegetritt No clue, sorry
Lenkkopf Headset
Seitensteifigkeit Lateral stability
Lagerspiel Bearing play or clearance
Streben (Sitzstreben/Kettenstreben) Stays, (seats stays/chain stays)
Schlauchreifen Tubular tyres
vs. Drahtreifen Never heard of this

Drahtreifen - clincher tyres, folding tyres?

Wiegetritt

This translates to 'pedal bob'. When pedalling hard on a bike with front/rear suspension, the bike tends to bob...

wiegen - to sway/cradle (a baby)

Thanks everyone,
is Wiegetritt not when you stand up to ride?

I have two more, then that's all:

Wechselschaltauge
Zugumlenkung

Thanks again

Wechselschaltauge - rear dropout (basically where the rear derallieur is attached to the rear stay)

Zugumlenkung - Can apply to brakes and also shifters. A point where the direction of applied force changes. i.e. pulley system for cantilever brakes.

If it's the bobbing of the front/rear suspension that is being referred to, then perhaps the term "travel"? I know "travel" is used as a measurement of how much a suspension (front or rear) will "give in" so to speak.

Travel is called "Federweg".

Edit: Just read a few articles and asked here at work, "Wiegetritt" means pedaling while standing up, like a racing cyclist .

I have to show off here since this is just about the only biking term I know in a language other than English:
in French it's called "pédaler en danseuse".
