5 Second Bike Quiz: The B-Tension Screw

Triathlon Forum
1

I am curious how many of you know what the B-Tension Adjustment Screw is on the Rear Derailleur, and what it is for.

If you know, say “Yup”, but don’t give it away.

If you don’t know, say “Nope”.

Until the other day, my answer was “Nope”.

I’ll give an answer, or designate someone who has said “Yup”, to answer, later today.

I think so.
(But I didn’t know that’s what it was called.)

4

yup.

5

Yup.

6

well, there goes the “poll” aspect.

7

Sorry.
I did not read the instructions carefully. He does not want to know what it is, but how many people know what it means. People seem to need league tables and statistics for everything.

“I don’t know what it is, but according to an internet survey 94% of cyclists replied nope. So I am okay.”

This fits right in with my Five Second poll of last week that asked “How many of you read the poll question before answering.”

I guess you answered both polls at the same time.

9

I was wondering how many knew, but the correct answer to the poll question was either “Yup” or “Nope”.

My reply had only 21 views. Should I delete it and you start again?

11

Delete? Yup

Ah–its no big deal. If you wanted to edit out your answer, that’s cool, but it is just all tomfoolery anyway.I’m just embarrassed I didn’t know what it was for. I thought it had something to do with keeping a certain amount of pressure on the chain.

You probably didn’t know you could catch this much crap just for answering a poll question, either.

13

Yup

14

its gone - remove the one you quote me.

15

Yup

the closer the top derailleur pulley is to the cassette cog, the more extreme the chain angle when switching gears. makes shifting faster. put the chain in your easiest gear and back the b-screw off as far as possible. If you go from a 21 to a 25, you might have to adjust it, but not a 21 to 23 or 23 to 25.
