You could do - what are you hoping to gain?

If you "upgrade the frame" you're really building a different bike and transferring things over.

@Criggie - where i live now, i'd survive about 10 minutes before someone hit me.

Generally speaking its cheaper to buy the whole bike than bitwise upgrades.

batman: in the box?

@JamesBradbury - good to know. deciding between teh thule and yakima.

@DeletedUser, @gschenk - considering it. certainly would help with aero

@Criggie - in the box?

ah. for reference, someone on my way home today cut several lanes (perpendicular to the direction of travel) to make a left turn in front of me.

Ouch - good you're OK. This is why I have a gopro cos people wouldn't believe the shit that happens out there.

yeah, no real issue. people are just idiotic drivers around here so i dont want to take my bike out around here

sucks to live in a cycling ghetto :-(

yep

I'm considering a headrest for the bent... this one comes recommended but at $200 NZ plus tax plus freight its a lot of money.

Opinions? I don't need an adjustable one once its set right.

idk. might be something you want to fab yourself; i doubt that thing goes through safety testing

Yeah I'm thinking of some aluminium stay with minimal bending and a plastic-backed pad as a headrest. Permanently bolt it to the bike's seat.

OK so I've spent $1118 NZ on my recumbent so far, and gone 2158 km. Effectively 52 cents per km.

That's everything that cost money - if I had it in the shed like a wire and the pedals, then it was zero-cost.

Hmmm... wonder what my cost per km is...

thats not too bad.

Let's see... 32,380 km... Call it about $1700 for the bike... Plus... uhm... at least a dozen chains, a few cassettes, lots of tires... a couple wheels... I think I'm probably at a bit over 10 cents per km.

yeah - I need 10,000 more kilometres :)

I put a fishing scale on the pedal and pulled it backward

its -550 grammes of force to move the pedal backward at the top of the stroke

Assuming its vaguely similar forward

I've also found the chain's digging into an axle where the idler goes

so got to buy and fit one of the,m

@Criggie, for a home made head rest, try to avoid metal, wood or hard plastic that can damage your head if the softer parts fail for whatever reason. The one I have, on the one bike came installed, has a triangle frame, where the two legs of the triangle fit into the uprights of its seat, the metal of the headrest going up above the danger point for me.

Looking for a photo now.

I have not often used it, the seat angle is such that I can easily keep my head upright and leaning back against the head rest does influence the balance and thereby the steering of the bike.

I can see the advantages when the seat back is farther down.

Ahh I see. Yeah theres no pipes like that to fasten onto.

Well I remembered to test the triple chainring with the alfine today - it works surprisingly well.

The middle chainring moves the alfine over by about 3/4

so what was 3 is now gear 11.

I doubt I will ever need the 22 tooth grannie :)))

Leaving me with just a bit more low/low and quite a lot more high gear - exactly what I wanted.

Sounds like the gearing I ended up with, when the new gears were installed. Last time I tested out the higher (faster) gear, I was going down hill as fast as I dared to go when I stopped peddling and gearing up and had half of the gears left.

Yeah - will get a photo of the other damage in a bit
