Homebuild - Super V15

58?!?!?! Jeez! That's huge! But I like it. I've got a 52, but wanting to get a 55. Can't wait to see you start using that 58 once you get used to it.

 

[bladderhead]

What everybody says about the chainwheel. I have 52 on my Grasshopper and that has small wheels. On my Silvio the chainwheel is smaller than the biggest cog. Are you one of these people who try to go over 100mph?

 

[Rob Lloyd]

Nah, the 58-12 combo is only good for 35mph at 90rpm. That's about my downhill top speed for most places I ride. For the 200m sprint at Waterford HPRA, it's not really enough.

 

[Rob Lloyd]

The 58-23 combo is a little steep for some of my hills, though. I will probably insert a 27 or 29 bottom gear, shift the cassette over 1 ring, and make the 13t the top gear. I did the same with my mid-racer. Kind of a mimi mega-range. At least, a close ratio 8-sp road cassette with a 'granny' low.

Oh, and it weighs in at 27lbs right now, with pedals. But, I am building up a lightweight wheel set for it that should drop a pound and 3/4.

My V20 weighs in at just 27 lbs with Sram Force group, Thor sport seat, thinner of the Ventisit pad, double bottle holders (no bottles), Shimano 8020 pedals, Rival 155mm crankset and Hope carbon wheels 40mm (about 1500 g for the set) wearing Conti 25mm tires. Oh, and a jam packed tool/tube bag.

You’re right in the ballpark.

Congratulations on the finishing the build and the first ride. That's a truly impressive machine. I'd reconsider the matte black paint. That beauty deserves some bling.

2nd ride, camera mounted on the boom. Still feels weird to me. Turning actually feels more natural than trying to go straight.

Congrats on getting the build on the road. Watching your vid brings back memories!

Rob,

your build looks great. Riding that well on a second attempt with cleated pedals and uncleared shoes is phenomenal. I had to use pinned flat pedals with flat bottom shoes when I started.

you are going to master this quickly.

you should probably try to find a wide no-traffic spot to practice tight circles and then figure 8’s. At the speeds you will be going, you will want those handling skills to be tuned up.

I hope to see your bike in person sometime this season.

Do you guys typically pedal while turning? It seems like pedaling while turning is ok for small angles at least. My RWD midracer can’t be pedaled while turning due to crank overlap. So it was nice to be able to pedal and turn. But I’m not sure how tight you can turn and still be able to pedal.

you can pedal while turning up to the point where your legs become uncomfortable or your foot comes off the pedal. When wearing clip in pedals, you can pedal with just the inside foot clipped in. This is, of course, dependent on keeping your knees comfortable.

as you surmised, this generally only applies at lower speeds. At higher speeds you would never turn the wheel that sharp and you can always pedal with both feet.

Your ability to build bikes is amazing. Your ability to ride bikes is amazing. The metallic look is amazing. Do not paint it.

Great job in building and riding your MBB Superbike!
You kept it straighter than I could when I first started riding, but as previously mentioned, I think you'd benefit from a traffic free parking lot to practice figure 8s...

Blessings and a job well done!

What @Brad R said. The only times I stop pedalling are when I have to because my inside leg is in the way of turning my handlebars far enough to make really steep low speed turns.

The other reasons are all the same as on my other bikes: I stop pedalling when:
-I want to stop pedalling, or
-turning at the edges of control where I don’t want any extra feedback interfering with a manoeuvre such as high speed corner, banked off camber from bike trail onto sidewalk with bollard in the middle, or
-courtesy for pedestrians that are (rightfully) scared of the toothed chainring, or
-unknown conditions (loose gravel/sand on the verge of the road.

Being able to pedal through a turn at 10 then 15 and later 20mph is a pretty good indication you’re getting the hang of it. Death grip coast through a turn is where most of us started.

I think I’m already past the death grip stage. I have 2800miles on my RWD midracer at the same recline and steering geometry. I’m just happy to not be worrying about crank strike or the chain scraping the tire. My RWD midracer is really fast, but it is not road friendly. I really hope this bike is just as fast.

i just cant ride that seat angle. looks great.

 

[Rob Lloyd]

Ordered a Viscoset for the top headset. Should be here tomorrow.

Haven't had this bike out in a few weeks. Got busy, etc. I need to find a big smooth parking lot to practice in...

 

[jond]

It's amazing they don't catch on. They can easily see my power heart rate data over my shoulder and see everything is lower than what their doing still they plough on.

it’s true. Plough on plough on its so unfair. Thank goodness.

You will need some bright flashing lights with that bike... its like a ground torpedo
