Highest Speed?

[Nigelnaturist]

I do love a bit of willy waving so shall read on to the end and enjoy

My highest speed is about the same as my slowest speed. I hate going downhill as much as I hate going up them so I only really have one speed......... slow

I prefer going up.

I chickened out at 59.9kph (37.2mph) on a fully laden (world tour) tourer somewhere near a town in Sweden which we renamed from Båstad to some thing more appropriate. It was sustained as well 3km in just over 3 mins - just wish the uphill had not taken hours beforehand. We had to slow down for a couple of bend and to go over some railway lines. Strangely vehicles stopped overtaking us on the downhill. My OH recorded 63.9kph (39.7mph) on the same section. Bikes were rock steady. Not sure my nerves were.

Without any wind assistance and as long as the hill is long enough to reach terminal velocity, on a ...........
2% hill, I'll hit 20 mph.
4% hill, I'll hit 30 mph.
8% hill, I'll hit 40 mph.
16% hill, I'll hit 50 mph.
Top is only 55 mph which I've reached twice on different hills.

Down or up?

I'll get to 40mph on the 4-8% but on the 16% I'll only do 20mph

Last July I managed 34.4 mph according to my Sports Tracker record here. I got up to 35+ pre sports tracker. All on my 30 year old steel tourer.

A 10 percent hill is where you hit max IMHO. Aero tuck no wind. More and you are on the brakes and the hill isnt straight enough

 

[HLaB]

I hit it well before that. If its a shallowish non technical downhill in good conditions or into a headwind I can power down it, I dont like steeper wheels and spinning out

about 75kmh. On a heavily laden touring bike in NZ - rock solid and clear straight road with an uphill to lose speed

This question re-appears every now and again on the forum.

Sounds like my kind of hill

48mph on damp roads, you're a braver man than me 37mph on a surface slightly dryer than this and that was enough for me

 

[Spally]

have to say as well, done a similar top speed on my hybrid, and probably due to the RB being new, felt safer at that speed on my hybrid.
