Fastest you've gone....

[Richard Sherratt]

I didn't do it, but ... Terrys Ave? - that near vertical street on the
left as you get into Belgrave. It's about 1:4. Very steep. 50 km/h
limit. 100 to 140 km/h guaranteed without pedalling. Only problem is
that there's a roundabout at the bottom and heavy traffic on Burwood
Hwy. You have to plan on going through the roundabout at about 80 to
100 and hope there's no traffic. Probably not a good idea.

Regards,
Richard.

You also get a good speed 80+ going down mona vale road heading to the
pacific highway at the 3M building. I used to do the f3 but the traffic
noise is awful. Much nicer doing to old highway. I love that road.

Point 3 below. My experience shows that bicycles can go through corners at
the advisory sign limit. Last weekend there were plenty of conrners out
near sassafras that were easily taken at the yellow speed sign pace.

Greetings,
Too many obstructions, chicanes, curves, and the final
run to the roundabout is too short and dangerous to pick up any real
speed. You could try Mast Gully Rd in Tecoma, but that has the same
problems. I have once come off Mt Donna Buang, 17 km downhill in 17
minutes, but that was pretty hairy.
Regards,
Ray.

If any of you get out to Moe, there is a bloody steep hill out the back of
the Wirraway St. extension. After school for a few weeks waaay back in 1990
my mates and I would have speed comps down it. It is 80m worth of hill with
a 200m run off. The most I got up to was 82...one of my friends got up to
92.

It was a stuggle getting up it in 42x23.

Not the fastest, but my most sustained high speed run was out north of
Melbourne on the 'Pleurisy Plains'. Lancefield to the Sunbury Rd junction,
36 kms in 35 minutes gave us an average 61.7 kmh. Pretty happy on this flat,
very gentle descent. The roaring northerly may have played a role

Otherwise try the descent into Lancefield from the Great Divide - 83kmh
tailing a tandem.

Or the Gordon Spur between Marysville and Narbethong - also 83kmh (later saw
the remains of some poor guy's front wheel, having blown out a tattered
single on the same descent. He was a hospital case)

Cheers
Peter

Could be. I haven't been up that way for about 10 or 12 years, but I
used to ride up to Belgrave a lot when I lived in Knox. I remember
looking up to the left as I was getting close to the roundabout and
thinking that you could get a good speed up there.

If you hang a right at the roundabout and head towards Narre Warren,
there's a hill just as you're leaving Belgrave where I got up to 77
km/h without pedalling in about 1989 or 90. This was on the way back
towards Belgrave in a Knox Bicycle Touring Club "Hard 100". (Miles,
that is.) I had nothing left after cresting the hill before, so I just
let her roll.

Regards,
Richard.

What would have caused such a blowout- a sharp object or something?

I convert the kph to mph and then back again - eg if the sign says 25kph, I
say "that really means 25mph which is 40kph, so I can safely take the corner
at 40". I've talked to several motorcyclists about this and they do exactly
the same...

83 down the old freeway from eagle on the hill. But I am fat you may not be.
My old mity 3 showed 473kph after the wire got chewed up between the
brake pad and the rim.
My new astrale 8 showed 120kph on my usually 60kph hill. Realised I
still had the old magent on as well as the new one.

The Noosa triathlon course has a great downhill.

I got to 83km/hr - and I only weight 61kg. One of my mates who weighs 110kg got
up to 87km/hr. the professional race winner (I guess he wold have the advantage
of some wind tunnel testing) got over 100.

Don't know exactly but we were all stunned by the _very worn_ high-pressure
single on his front wheel that had blown out, and the brand new single
strapped under his saddle. If he'd have ditched that old tyre before the
ride he would've been OK.

Strictly speaking, tires can support 115 km/h without problem, and they
won't blow because of speed. They may blow up if you drag the brakes a long
time and overheat the rims (and tires), or because of a sharp object, or...
And at such a speed, you'd better be good at controlling the bike.

managed (only) 58km/h coming down the Westgate Bridge on the ATB. It's a
record for me - as I get older I feel less invulnerable! I was ******
off that I didn't break the speed limit, but I did pass plenty of cars

Never argue with an idiot. They drag you down to their level then beat you with experience.
