Hi Randy. Thanks for the Hi Randy. Thanks for the link. I've seen it in the past, but didn't remember it very well. Here's John's picture. I like it because it explains quite nicely what is going on. Two points: * Crank leverage can change quite a bit for...

Hi Randy, Thanks for the Hi Randy, Thanks for the pictures, they help a lot. As far as whether or not you did it right, it depends on how your leg hits the crank. You wan the chain to be as far away from the bottom bracket when you are on the power part of your stroke. So a change...

Hi, When I was riding in this Hi, When I was riding in this morning and I was bridging to get up the last hill before work, I noticed that I was pushing quite hard against the handlebars to get my butt out of the seat (while my shoulders were planted against the seat back). I've never...

Just switching Just switching to cone spacer washers lock nut Should be an immediate improvement for installing the wheel.

Hi, There have been a lot of Hi, There have been a lot of successful conversions of non-Y frame bicycles. The biggest issue that you have to worry about is the seat height. Will you be able to sit in the seat and easily get both feet on the ground? Posting pictures of your bike will...

Hi Jim, I've only ever seen a Hi Jim, I've only ever seen a Sofrider in person (and only my bike). So take that into account. The Sofrider is the cheapest (which was definitely relevant to me); it is also the heaviest. The standard double doesn't go nearly low enough for me, but it...

Hi BK and everybody, For what Hi BK and everybody, For what it's worth, whenever I hear pinging noise, I think loose spokes (when I saw ping in the subject title, this was my guess before clicking on the link). Since it is usually cyclic with the wheel rotation, you can generally ride a...

Hi, I'd be leary of having Hi, I'd be leary of having different sized wheels. You might be able to get some of the difference to go away by adjusting the rear suspension, but probably not enough of it to make the bike behave as intended. I say this with absolutely no experience here to...

Hi Hilry, One last crazy Hi Hilry, One last crazy thought: Buy a 20" fork and use 20" wheels on the conversion. You'll have to figure something out for the rear brake. Height should definitely work for you in that case. Cheers, Charles

Hi Kidney Boy, I completely Hi Kidney Boy, I completely agree that it's not obvious. I'm thinking a full (ish) fairing with a wind wrap - (a la F40). I agree that this will be easier with the more upright Silvio, but I think somebody who knows what they are doing ( i.e., not me), could...

Hi, For those of you who are not regular BROL forum readers, here's a topic about a french recumbent hill climbing contest. MBB bikes (both Cruzbike and Zockras) were very well represented. Cheers, Charles

Hi Hilry and Nick, The 451 Hi Hilry and Nick, The 451 Quest (really 22" wheels, not the 20" wheels you see on most folding bikes - not Cruzbike's fault as both are called 20") is what I'd suggest for both of you (I'm guessing Nick is ridng the 26" wheels above). Lower seat height means...

Hi Randy, (*cough cough Hi Randy, (*cough cough cough*) Pictures (*cough cough cough*). Thanks. :)

Hi, There is a technique Hi, There is a technique known (at least on BROL) as bridging. One plants the shoulders firmly against the back of the seat and lifts the butt off the seat. This technique requires good core muscles, and since I am lacking in that department, I can only do this...

Hi, A great write-up (keep Hi, A great write-up (keep 'em coming). Sounds like a beautiful ride. I'm curious what happened to your derailleur that prevented it from shifting. Did the cable seize up? And I've never had wi-fi at 33,000 feet, but yeah. It would be awesome. :)...

Hi, For a hardtail bike, I Hi, For a hardtail bike, I think if you end up with something with a higher seat height (by about 3") if you designed it for 26" wheels and put on 20" wheels than if you designed and built it with 20" wheels. If you are planning on swapping out the fork and...

Hi, @tallaussiesje:  Weight Hi, @tallaussiesje: Weight only matters for climbing and acceleration. Air resistance matters for everything. This is why velomobiles (which are usually twice as heavy as regular recumbents) do so well as far as average speed over a given course. :) @Jim...

Hi Jim, I'm assuming you are Hi Jim, I'm assuming you are talking about http://www.analyticcycling.com/ and this page in particular. Quite cool. At higher speeds, air resistance is pretty much everything (which is quite consistent with what your numbers above showed). I guess...

Hi, If you're huffin' and Hi, If you're huffin' and puffin' on an upright, you're standing up and the bike is actually rocking side to side. (O.k. it doesn't happen when I try to ride DF fast, but when the pros do this is what happens). When you push hard on a Cruzbike you get pedal...

Hi, For what it's worth, I Hi, For what it's worth, I bought SRAM X.4 Trigger shifters for $24 here in the US. Since I installed them myself, the total cost was $24. The exchange rate is pretty much even at this point, but I don't know if bike pieces are more expensive down under or not...
