I have to point out again that there has never been a prohibition against front discs in any OBRA TT race. There is no increase in risk, just the same risk which was present before. It would be easy to propose a rule prohibiting front discs in road TTs. In fact, I think it would be reasonable to prohibit front discs in all OBRA events given that we do not have an indoor racing venue. On the other hand, given that there has never been an issue with a front disc at any OBRA race, road or track, mass start or TT, any rule prohibiting them in some subset of races may be a solution looking for a problem. The focus of this rule change was rear discs in road mass start road events. I don’t see any reason why a rear disc would be safe in a mass start track race but not in a road event. Actually, I really don’t see why a rear disc would be dangerous at all. My argument, however, did not carry the vote.

That reasoning isn't logical though. An out of control double disc bike over taking slower riders puts both riders at risk. Combine that with a double disc out of control pass plus an oncoming car leaves very little room for mistake. The same is true if a slower rider is setup double disc and white to yellow lining when a faster rider tries to pass.
I'm happy with the rule, but it does increase risk of collision between two riders passing and between a rider and an incoming car.

There never has been any OBRA rules prohibition against disc front wheels in TTs. This rule change only makes disc rear wheels illegal for mass start races except for on the track. In other words the new rule is more restrictive rather than allowing something new. The argument was that using a rear disc on the road in a mass start race is dangerous. YMMV
I agree that using a front disc for anything other that a windless TT event, i.e. Indoor track, is pretty dumb. The reasoning behind not prohibiting them for TTs is that the only person that would be at risk is the person that elects to use them.

Interesting. Road TT's now allow disc front wheels. That will make for some excitement !! Especially at Jack Frost and Peoria where it's ALWAYS windy.

Modifies rule 7.3.4 Wheel restrictions
Fully enclosed or disc front wheels or spoke covers on front wheels are not allowed in mass start events.
To:
Fully enclosed wheels are only allowed in time trial events, with the exception of track events, where a rear fully enclosed wheel may be used in all events.
