Gear Restrictions - Blocking Front Deraileur

[Young Un]

I am soon to start doing youth circuit races, but for these races you are restriced to a gear development of 6.93m. I have worked out that using my 42 ring, combined with a 13 tooth on the rear will give we a devepment of 6.8 and therefore legal. I do not want to take my deraileur off completely, although I may have to do this to allow me o use all the gears whilst still on the 42 (middle ring). So how do I block my deraileur?

Cheers
Steve

Just use the limiter screws to screw it off.

Have you checked the gearing is right?

 

[Young Un]

Not yet Dave - going to do it tomorrow.

SO are you saying put the chain into the middle ring and just screw the limit screws right in?

 

[RedBike]

Just screw in the high limit screw. Leave yourself the option of changing down. (You shouldn't need this though.)

 

[Young Un]

Cheers Guys - may have a go tomorrow, dependant on whether I can get my coursework done.

You might be able to switch your outer rings to 39/42 instead of 42/52 (or whatever they are) or use a set of track bolts to remove the outer ring all together.

Don't Think I want to remove the ring alltogether, because I may put it back to normal for roller racing/time trials/ general road riding imbetween teh circuit races.

Why? Gear restrictions exist for a reason.

Anyway, as regards general riding you should train on the gears you race on - or lower.

So what's 6.93 in English - 72/74 inches ?

That it what I plan to do from now on.

And Dave do the same restrictions apply to both Road Racing and Time Trials?

86/87 inches I think

 

[Young Un]

Cheers guys for the info, have just blocked it off now, worked a treat!


Cheers Guys!!

 

[Dave5N]

Not sure they do for TTs. And Roller racing is I think a Junior gear - 7.93 from memory. Certainly BSCA ones are.

Anyway, your knees...

I'll email the organisers about the gear restrictions on time trials.

Also with roller racing I think I am only going to do it as an in-club event so I don't think we will bother with gear restrictions - we certainately didn't last time.

A racing club would.
