If you had a look at the web links on the right side, you might found the link to John Hawks blog. I’m following his blog for a couple of years now and greatly enjoyed his online course ‘Human Evolution – Past and Future’ on Coursera in 2014.

Human evolution is a fascinating topic and he is a great lecturer. Anyway, here is his presentation about Neandertals, that’ll give you an overview about what we know of them.

Nasty’s new 700c rear wheel

Today, I’ve looked for a 700c tyre to get the new rear wheel rolling. The easiest would be a Kojak in 700c size, to match the 26″ Kojak’s at the front, but I had something wide and quick with at least some thread in mind. The first bike shop only offered Marathon Plus and skinny Schwalbe Lugano in 700c, but the second shop had a much wider choice and offered a Conti Cyclocross Speed in 42-622 for a mere €13.

I wasn’t sure if such a wide 700c tyre in the Sprint rear frame would allow a rear fender (you really want a rear fender in a trike to save yourself from crud in your hair), hence I went for a cheap tyre for the first try-out, but it fits rather perfectly.

The seat is set a bit higher and the rear frame inserted all the way into the front frame. The wheel base decreased by 4-5cm and, since I got slightly more weight on the rear wheel, the rear doesn’t like to slip-out slightly when going hard around corners anymore.
That small change in handling was already noticable with the bald 26″ Kojak yesterday and more apparent on my first ride with the finly treaded Conti, today.

More importantly, ‘Nasty’ looks way more balanced with the combination of 26″ at the front and 700c at the rear, than with 3×26″ wheels. 🙂

The new rear wheel. A matt black H Plus Son SL42 rim with the 42-622 Cyclocross Speed.
Rats! Cut the chain too short, I’m afraid, since the bottom bracket boom may need to come out a further 1/2cm.

Nasty got new wheels

This gallery contains 4 photos.

Yeah, I know… I had every intention to ride with the 20″ front wheels for a while, but it was raining on the weekend. I got bored and instead of watching TV, went on a little wheel building spree. Five … Continue reading

Blue ICE with Kojak

Since the new 24″ Kojak’s needed some breaking-in, I’ve put them on the Blue ICE.

Looks like the front wheels are probably a bit out of alignment (the rod end bearings are worn-out), since the tyres show some wear already after a mere 33km. While that’s perfect in this case, I’ll have to check toe-in tomorrow and ordered some new rod end bearings.

I’ve also swopped the Patterson Metropolis to a new one with cranks shortened to 155mm. The shortest crank size available for the Metropolis is 165mm (that’s what I was using for about a year), but 165mm a bit too long for comfort and makes my knees hurt after a while. The Patterson with 165mm crank size went in the (still not finished) Black ICE.

Wheel size change

This gallery contains 4 photos.

Today, I’ve installed new IGUS rod end bearings and a older 20″ front wheel set with 28mm wide Sun Rhyno Lite rims, shod with skinny 28-406 Schwalbe Durano. The rear wheel got a 50-559 Kojak again. While handling is very … Continue reading

Completing ‘Nasty’

‘Nasty’ is more or less complete by now. After some more rummaging in the parts bin, she got a head rest, a B+M IQ-X E (150 lux) front light and a third rear light. To move the handle bars a … Continue reading

Critical Mass in Hamburg

This gallery contains 2 photos.

Took ‘Nasty’ to the Critical Mass in Hamburg yesterday. That was fun! Haven’t attended in ages. There where only few recumbents, but I counted three HPV Scorpion RS 20 trikes in the same brownish-orange colour. Found a pretty nice video … Continue reading

More ‘Nasty’ images

This gallery contains 5 photos.

Changed the front wheels to a wheel set with sturdier rims (DMR DeeVee 32-507), shod with Schwalbe Shredda Evo 50-507. The worn-in Shredda handle much better than the new Kojak. The brand new drum brakes felt a bit weak yesterday, … Continue reading

Today, ‘Nasty‘ got mirrors, seat bags, a speedo and some lights.

Tomorrow, she get some faster tyres. The Kojak’s are ok…ish, but I’m curious how they compare to a pair of 24″ Shredda Evo and a 26″ Marathon Almotion.
