Totally inspiring , is he intending to keep racing the recumbent?

Yes but life has gotten in the way in the form of a new job and I've almost no personal time these past 6 months to ride or do much of anything. Team Cruzbike has kept in touch with me as to my plans for future races but I've been unable to commit to anything. I will race again, I just can't say when or where at this time.
 
Great write up Jason, Jim. Really showing the world what we can do. Would be interesting to see Froome et al on a V20.

I had my own a-ha moment yesterday when I had a upright drafting me into the wind on my S40, re-confirmed my choice

I’m such a damned slug! But it’s a great read.

Still, enjoying my own small victories like ElyDave. Pulled a group of DF racing friends along a 6 mile stretch the other day. Think they were all sitting back, licking their chops for the approaching 2.5 mi, 10% climb. Too bad none of them found the legs to pass me on the hill! Alas, some of them did finally best me on the last climb of the day - a 1/2 mike 18%er.
 
I didn't realise @RojoRacing and I were the same age. Unfortunately I am in a completely different class, that is father of twins :p.
Really interesting read and congrats Jason on all the great work. Hopefully I will get in a ride or two in the school holidays. I am also hoping to get back to commuting, after.
 
Nice video @RojoRacing .

I was surprised to see the huge cadence difference between uphill and downhill for you. I am not on a CB yet and maybe it will be more apparent then. I do understand the difference if gears are the same, but usually that would be odd to use the same gearing climbing and descending. Is the difference a by-product of the platform or did you run out of gears? ;)

When I started riding bents, all I heard was to keep the cadence up around 90+. It is interesting to see you climb at around 80RPM. I have done a few training rides with lower RPM, but mostly I still stay close to or over 90.

Who were your Q-rings from? Do you really notice a difference from circular and in what way?

There is descent where I can get to 40mph, if I pedal flat out and exhaust myself so I can't get up the other side, and I can only do it because it is so steep. Jason was coasting at over 50mph on an almost flat gradient. Goes to show the Silvio has better air-brakes than the Vendetta.

His road surface is good. I would be terrified of hitting a hole at that speed.

1. I was surprised to see the huge cadence difference between uphill and downhill for you. I am not on a CB yet and maybe it will be more apparent then.

3. Who were your Q-rings from? Do you really notice a difference from circular and in what way?

1. If you watch the whole thing and listen you can hear me down shift two gears to my lowest at the hardest part of the climb so I start in 3rd gear and drop to 1st. I'm already in my lowest gear and pushing well over 300 watts on a climb that's well over 10 mins long so it's a sustained effort but yeah I'm out of gear at that point and unless you can push 350 watts or hold a cadence of 50rpm you're going to be walking with my low gear of 36f-32r. On the downhill I go strait to my tallest gear 52-11 which spins out at around 45mph at a cadence well over 100rpms. What you seem me doing on the DH are short burst efforts similar to sprints so I can get my speed back over 45mph and go back to coasting. If you've ever watched pro cycling you'll see the riders cadence during sprints or breaks is far higher than their average no matter what gear their in and that's because it suits that type of burst effort.

2. Don't take everything you hear from bent riders to literally most don't know what their talking about when it comes to performance value or their sample is less an average and more an outlier this is true for any type of rider bent or DF. I run fairly standard length cranks at 165, 170 or 175 on all my bikes and I'd say my happy cadence is high 80's as an average but I tend to drop those value when climbing and raising them when going fast like on a slight dh doing 32 mph I'll be into the 90's. This it true for all my bikes so nothing special about the bent.

3. I've used Q-rings in the past but these are Qxl rings which I think I got from @ratz. You can get them from most online retailers but they are rarely ever discounted unless you buy used from ebay. I just went back to Q rings on my DF bike I scored a set of 53-39 rings for $62 and they only had a a dozen or so rides on them. I'd say start with Q rings and move onto Qxl in the future if you like them and want more. Check the forum here as we have several threads about the Q rings and their special setup.

You're right that this road is rather smooth but what it has are lumps(the smooth dark spots you see) and in my experience at these speeds lumps are crazy dangerous on a bent. On a DF bike you float on your hands and toes going down so your body absorbs the jolts from lumpy roads. On a bent you whole body weight charges the frame with a bunch of stored energy when you hit the lump and as you go over the frame rebounds and releases that energy sending you into the air or at the very least your legs which influences the steering on a cruzbike heavily. At 5:50 you can see me take some rather odd lines over the next part because if I were to take the normal line I would get my legs tossed around over the black stuff and end up in the barb wire. Really only an issue for me when going faster then most rider are willing to go so it's a mute point for most people. If I'm not mistaken I took the KOM on in that video which ain't bad considering how highly contested that road is with local racers.

I nearly left the road on my Silvio because of a tiny bump. I was doing 30mph. Putting Tannus on the Grasshopper made me realise the importance of the air tyre's flexibility. Tannus is definitely not for the Silvio.

Yes at that speed road surface quality and brake tyre trust riding the vendetta are premium. It’s not so good getting air on the vendetta or any road bike at 100 klm / hr . Not much chance of coming back from an off . Great video Jason. Terribly exciting. Your bike handling skills do you proud. Incredible vista like riding on a different planet. Addicted to climbing and descent reward warp speed. How impressive is the vendetta the phenomenal pick up in speed is an unbeatable thrill no df tuck can match.

Have you ever done a fast descent only to realise that something has winged away and fallen off . Conundrum do you turn and climb back up for a $100 item. Only to think you see it blur past you on some other bike minutes later.

I was riding in London in the winter and my bobble-hat flew off.

Lol noddy goes to town.

I’ve climbed back up to retrieve a flag...... dubious...and to retrieve an iPod worthwhile. But I’ve left behind a couple of visors and clear glasses.
