Allsop Softride Powercurve - Gotta scratch the itch!

Showed up locally and I've always been curious about these. So I grabbed it. Came with everything in the picture as well as the original Shimano 105 wheels and a third water bottle. Guess in the spring we'll see how smooth my cadence is after a winter on rollers, LOL!

I really know nothing about these or even what year this is. This one is Tange Infinity steel and not exactly light. 24 lbs 2 ozs as in the pic. The "aero" wheels look cool but my understanding is that tend to be pretty heavy and flexy.

Anyway Shimano 105 7 speed components other than the wheelset on it which is equipped with a 10 speed cassette right now.

One quick pic of how I brought it home.

I have 2 still and the advice I give is sit in the seat and let the suspension work. Do not lift your rear when you see bumps coming. You will ride faster and better that way. Roger

Careful setting up the front shifting, especially with STI. The front derailleur location on these bikes is too close to vertical--more like 11 o clock than 10. For sure install a chain watcher--or use bar end shifters. I was the warranty person at a shop that sold these so my view is a little jaded. Also there are no replacement new beams available and they do delaminate.

Have no clue what I'm going to do with this or if I can really even ride it. From reading about these in the past I thought the various beams were rated for a max weight. When I went to get this I didn't see any weight range on it. There is a label on the bottom of the the beam between the two mounts but it was too faded to really see anything printed on it. That may be where the weight range was.....

Curious about the purpose of this one. Rear has mounts for rack/fender. I expect the original front fork did too.

They were rated at a riders weight but I have ridden with beams that were not for my weight and could not see/feel a difference. Besides my 2 my wife had one and we had a Burley Rock and Roll tandem with a beam in the back and that was maybe the best application of them. I will see if I can find some pictures. Roger

Found some pictures. Red one is a pre production bike and the other is a production bike. Rode the red across the USA west to east in the mid 1990s. Roger

Back in the day our shop saw a few of these come through. Interesting idea, but I also believe the best application for the beam is on a tandem.

I liked the Aerospokes and they are still on the bike. Bought them a a swap meet from 2 different vendors as a mismatched set. At this point they have thousands of miles on them. Roger

I ad an off road model that I really enjoyed until someone offered me too much money for it. He had contacts in Japan that would pay dearly for anything manufactured in the US.

I dunno, but if you don't like those wheels, you know where I am, perfect for a Look KG196.
A lot of those were 650c too. I'd like a Softride, fits right in with the Y-Foil as significant and oddly attractive.

I have a Solo in the stand now with clamp secured on the upper tube where you have a bottle carrier and pump clip.
The clamp turns 360 degrees so the bike can be positioned as needed.
Looks like you might have room on the short vertical tube in front of the rear wheel too.

I also have a Power Wing that doesn't play well with the repair stand.
I have had to place the clamp on the beam for that one.

Yep, I checked with the seller before I made the drive to make sure they were 700c wheels. Since he was giving up two sets with it. I do like how the Gipiemme wheels look on it so hopefully they work for my current 190ish pounds.

Out of curiosity I compared the weight of the two front wheels with their current tires and skewers. 2 lbs 11 for the Gipiemme and 2 lbs 13 ozs for the Shimano 105 hubbed Araya rimmed one.

Getting ready to take off all the computer stuff and those Campagnolo Aero bottles and mounts. I wonder if there's any value in these used bottles as they go for crazy money NOS on Ebay. I'm not sure what I'm going to do with them since I ride all my bikes. They'd look cool on the blue Lemond Maillot Jaune but then I couldn't take out real bottles when I rode it.

Anyway, the clean up begins. The parts seemed to be working ok but they haven't bee cleaned in awhile from the amount of greasy buildup on them.

I used the very short seat tube (front derailleur mount) on mine for bike stands. It worked with Blackburn ones. Roger

I had a Softride Powerwing 650. It took a while to compensate for beam sag and get the saddle height and angle correct. The bigger problem for me was the beam width, as it rubbed by inner thighs. This was a minor issue when riding in cycling shorts but became a major while wearing a Speedo for triathlons.

Alex Steida, the 1st North American to wear Le Maillot Jaune, competed on an Allsop for the Evian-Miko team circa 1991.

Well, I gave it a pretty good clean yesterday outside. A bit of a challenge since it was in the 20's.

I was curious about tire clearance on this so I threw on a used set of Zonda's I have on hand that have a set of 700 x 27 Vittoria Open Pave CG's on them These clear with no problem. In fact, there seems to be a few mm's room left at the worse spot under the rear brake bridge. Put the cleaned up original 7 speed cassette from the Shimano wheels on it and swapped the Look Delta pedals for a set of Look Keo's.

Took off the Campagnolo cages and bottles and swapped in my normal style.

I guess the Gipiemme wheels weigh a lot along with the 1/2 lb of gunk I cleaned off the drivetrain. It's now down to 22 lbs 13 ozs. I'll probably run it with the GIpiemme wheels though if they ride good for me.

Not sure how the owner was running this with the 10 speed setup. Even in friction mode the rear was a mess as he still had a 7 speed chain on it. I pretty much couldn't get it to run smooth in any gear. With a 7 speed cassette on it it's working fine and the indexing is back working properly.

On my red bike I had a triple with 7 speed freewheel for 21 gears. That was my cross country bike. I used Shimano stuff from mountain bikes. Rear was 12 to 28 and front was 28, 38,50. The 28 to 28 was useful going over the Big Horn mountains. The red bike is one of 1 of 100 prototype bike Alsop used for testing the concept. Actually frame number 49. They were by a NW USA builder named Paul Barkley. The beams were sold as a kit to retrofit bikes originally but the people who used them said it made the top tube to high to ride comfortably. That is why they made bikes around the beam. If you are old enough Alsop was a plastics company that was famous for making an adapter to use 45 RPM records on a normal record player turn table.

Well, I checked this for clearance of Conti GP 4000s II 700 x 28 and as I figured, to close on the rear to be safe even for me. Rear brake bridge just barely cleared by like a mm.

Took the RD off and partially apart to clean it. I don't think this bike was ever cleaned as much rock hard gunk I keep finding built up on it. Even the heavy duty Pedro's struggled to loosen some of the concrete like grease.

Got done and was going to take a lap or two around the block for a little test but nope! Snowstorm had snuck in while I was working.
