RL’s Pet Project: Full Suspension Single Speed Bike-Maiden Voyage

Posted by RL Policar On January - 13 - 2008

I think I’m done with my bike, meaning I don’t need to tweak it any more. I installed a KMC chain that I had in the garage, though its vintage, its brand new. I took the advice of Jack “Ghost Rider” Sweeney and use a 3/32″ 6-8 speed chain. Doing so actually eliminated my chain skipping problem.

What I like about the Yess PRO FS/SS chain tensioner is the adjustability of the unit. I tried out a 32/20t combo and found that it was way too low and found myself spinning like a hamster. So when I went to a 17t, I thought I had to break the chain again to change the length. But no! With the Yess PRO, I was able to adjust the spring tension because it uses a standard V brake/canti lever spring. Once the tension was set, there was no need to break the chain to accommodate the 17t cog…nice eh.

He’s a handsome bike.

Having just one gear naturally limits your climbing ability…well not really.

Today at the Fullerton Loop, Priscilla accompanied me on this daunting task of making sure the bike is legit. I had to test the integrity of all the components installed by mashing on the pedals, jumping and doing what ever I can to put stress on the bike. So far, nothing broke!

We rode about 10.5 miles of the Loop and I have to tell you, there were a few times when I dry heaved because I was exerting myself more than I normally do. On each hill, I was mashing each pedal stroke and to be completely honest, I thought something was going to snap on the bike. But like I said, nothing broke.

What surprised me most about this rig was the fact that I spun as much I did. Here I was thinking that I was going so frigging slow. But when I would look behind me, Priscilla was further back on the trail than I expected. She did compliment me though, she said that I was pretty fast…faster than I would be on my regular geared bike…huh? How could that have been? My only guess is that since all my options of having multiple gears was taken away, I made the best of what I had. Through out the ride, my legs were on fire! Lactic acid and I became really close.

On one of the hills I was trying to climb, I sped up to build momentum, I was standing the whole time and I pushed myself to clear that portion of the hill. Once I got to the middle section where I had to turn left to do more climbing, I stopped. I got dizzy and started gagging, and tried to throw up! While I’m doing that here’s Priscilla passing me on her bike and at the same time she’s saying…”C’mon! Get it OUT! Just throw it up! You’ll feel better!” I knew she was right, but I couldn’t get anything to come up! Bleh..I hate that feeling…

The nausea finally surpassed and I was able to gain some sort of composure through out the ride, but my legs were spent. By the time we got back to the car, I was was worn out. But this was a great feeling. Yes I was tired, but also pretty excited because of the potential I see in the bike. Sure the bike has less gears, but that’s the beauty of it, less is more. No problems, no hassle, and all the same pluses of riding a regular full suspension multi-geared bike.

I’m not going to lie to you, this was a brutal ride for me. Legs were burning, lungs felt like they couldn’t get enough air…but hey..it did provide a great work out. I do look forward to riding my new favorite bike. I figure if I can just ride this bike a minimum of 2 times a week, I’ll already be ahead in my fitness level than I would be if I rode a multi-geared bike with the same amount of saddle time.

RL’s Pet Project: Full Suspension Single Speed Bike Part 2

Posted by RL Policar On January - 8 - 2008

Today I received the Yess Pro Full Suspension Tensioner. One I got the chance, I slapped on the hardware and tried to see how it works.

Here’s what I got…

The tensioner can work with a hard tail, the only difference that is has for the FS…in my opinion, is the roller that you install onto the pivot.

Here’s how it looks.

But now I’m having chain skipping issues. I suspect that my chain is all fudged up since I had to lengthen it. Since it was getting late, I decided to leave it for another day.

RL’s Pet Project: Full Suspension Single Speed Bike Part 1

Posted by RL Policar On January - 6 - 2008

Today I was able to set up the Full Suspension Single Speed Woodstock 707 with a SS chain ring, spacers, and a 17t cog in the rear. As far as the chain tensioner, I’m still waiting on the Yess FS/SS gadget, but since I wanted to start riding, I purchased an inexpensive chain tensioner to see if it would work. So far so good.

I headed down to the Jax Bicycle Center in Fullerton. Matt K gave me a hand in installing the tensioner and setting up the chain length.

Side profile shows chain tension.

One of the concerns I had with this set up was having enough tension around the cog. But the tensioner we had installed seemed to be working just fine.

So to find out if the chain/cog/chain ring would skip, I had one of the guys, Scott, do some bunny hops around the store to see if he could get the chain to jump or completely fall off. If you watch this video, you’ll see that it doesn’t budge.

Now the real test would be how well the bike does out on the trails…stay tuned.

RL’s Pet Project: Full Suspension Single Speed Bike

Posted by RL Policar On January - 3 - 2008

MtnBikeRiders.com has been known for its many bike builds and projects. The newest one to hit the work stand is my very own project. You all may remember my Woodstock 707 frame that I stripped down to the bare metal. I was going to polish this thing until it was a mirror finish…but I didn’t have the patience to do so. I basically left it the way you see it.

So what’s this new project that I’m cooking up? Well originally I wanted to build a single speed bike. Some of the fittest people on the trails I see these days are guys that ride single speed bikes. I had all the parts for it, well almost, but we’ll get to that later. I thought about using an old steel or aluminum frame I had. But after talking to Khoa, he told me that MB Action magazine recently built up a Full Suspension and they made it work!

The problem that I hear the most about FS/SS bikes would be the chain. Some say that it wouldn’t work because of how the suspension compresses and the chain tension and all that jazz. So I asked for the help of some of my bestest buds in the business. I called Scott Finch of RPM Cyclery and he was familiar with that article that Khoa mentioned and said that as long as I had constant tension on the chain that it would work. My buddy Vince Rodarte of KHS Bicycles said the same thing, I also called Jax Bicycles of Fullerton, Nathan Burke reiterated what the other fellas mentioned.

Then there was our very own Jack “Ghost Rider” Sweeney. He directed me to a company called YESS Pro. They actually make a chain tensioner for Full Suspension Single Speed Bikes!

I was going to use some old cassette spacers and an old 17t cog for the rear wheel, but I quickly found out that the spacers had these little keys that needed to be flushed mounted onto the rest of the cogs in the cassette. That basically meant that this idea was shot. So that led me to the Pricepoint.com Single Speed Conversion Kit. This thing priced around $13!

Here’s the tale of the tape:
Woodstock 707 frame
Manitou Radium Rear Shock
Manitou Axel fork with 100m travel and lockout
Axel Disc wheels
Hayes MX2 Disc brakes and rotos
Tektro Brake Levers
Uno 2 inch riser bars

Yess had already said they are going to send me the tensioner. I’m working with Pricepoint.com to see about getting the Sette Conversion kit sent to me as well. Other than those two parts, the bike is about 80% complete.

I’ll keep you all posted with any updates I may have.
