Goldsprints FX – Roller Testing

After picking up the CycleOps rollers from Rassy’s today I assembled them without much difficulty. None really. I just had to take the rollers out of the box, unfold them, move the front roller all the way forward, mount the fork stand, take the front wheel off my Swobo Sanchez and mount the bike to the rollers and swapped out my clip-in for some cages. A final adjustment of the fork stand and I was rolling. Pun intended!

After a few spins I took the bike off and disassembled the roller frame. I had to remove the rear roller and mount my rare earth magnet to the plastic end for the drum. I used small screw and it mounted with out issue. I removed the rubber band off the drums since I don’t need when using the fork stand. I put the roller frame back together. Final task was to attach the OpenSprints hall sensor to the frame so it could pick up the passing of the rare earth magnet. I used one of my wife’s elastic hair things as a temporary way to keep the sensor from moving.

Here are to quick screen shots of post race results from my testing tonight. I did a few solo races to tests everything out. I have some work to do on the rollers to get into sprinting shape! My Swobo is running 38/16 so I will probably go 38/18 if I have to use this bike for races. But I am hoping a sponsor to give up some frames or full bikes when the race time comes.

All that is left now are a few tweaks to the interface of Goldsprints FX and I can release it as beta. I already have about 10 people/groups wanting to test the application. East coast, West coast and as far away a Italy are waiting on the beta. I can’t wait to see the bugs they find! If you would like to sign up for the beta see the previous post for instructions. You will also need to fill out this

Our First Sponsor – Rassmussen’s Bike Shop

Today the fine people down at Rasmussen’s Bike Shop became my first sponsor. I went down to get my CycleOps rollers and they game me a sweet deal. I was not expecting that so it was a big surprise. Much respect to Rassy’s and all the fine people for supporting Goldsprints FX.

Sponsor

I will be adding sponsor logos to the top area up by the twitter image later tonight. If you are interested be becoming a sponsor please contact me on Twitter or direct email at ed at goldsprintsfx dot com.

In addition to building Goldsprints FX I am in the process of setting up goldsprints in my area. Last thing on my list is getting bikes to use at events. So just in case any bike manufacturers are listening hit me up. Parts or complete bikes would be mucho appreciated. In fact anything that helps me continue building Goldsprints FX or get goldsprints up and running in my area would be much appreciated!

CycleOps or Kreitler Rollers?

Black and Gold SetupI was just poking around the web looking at rollers again. I was pretty dead set on the Kreitler 4.5 rollers. But now I see that the Black & Gold out of Pittsburgh is using the CycleOps rollers. See the photo from the Black & Gold site to the right. Those are the CycleOps rollers for sure.

That is now two clubs (Black & Gold and the KC Sprints group) that are using the CycleOps system. As I mentioned below the CycleOps uses the 3.5 inch drums and they are an inch smaller than the Kreitler system I was looking at.

I sent the fine people at Black & Goldan email asking how they like the CycleOps system. My local show shop carries the CycleOps so it would save me from ordering anything online and support my local shop. If Black & Gold comes back and says they are happy with their system I might have to take a second look at the CycleOps system.

Here is what uNkY jOIns said when I ask him on flickr about the CycleOps rollers

The rollers themselves work fine, but we had to build box platforms to mount them onto when we are at an event. This helped a lot with the wobbliness of the stage and drunkards getting on and off. The boxes were incorporated after seeing the Coldsprints crew in MPLS setting up in a similar fashion.

Here is a photo of the KC Sprints setup on the left. You can see the boxes they built for their rollers. Then on the right is the Black & Gold setup. Their boxes are a little different. I think they encased the frame of the rollers into the boxes but I can’t tell for sure. Maybe I can get someone from Black and Gold to swing by and comment.

So now I am on the fence on what rollers to buy. CycleOps or Kreitler?

UPDATE: Brad from Urban Velo and Black & Gold told me today that he can’t say anything bad about the CycleOps rollers. Check out what he said,

The CycleOps rollers are cheap and work just fine for me, I see no reason not to use them. So far so good, no problems at all.

I have since updated the setup and sandwiched the rollers between two pieces of OSB, keeping the setup enclosed and cleaner looking, along with providing a platform for people to stand on and swing their leg over the pretty tall contraption. Equipment wise things have been just fine.

Ordering Rollers Monday

I plan to order rollers on Monday. This is the next step in testing Goldsprints FX. I have gone back and forth on what rollers to invent my money into. After a few weeks of searching, reading, and asking around it has come down to three option. All the other groups I found used either the Kreitler, CycleOps, or build their own roller frames. For the groups that build their own frame they used the Kreitler drums.

First option is the CycleOps rollers from Saris Cycling Group. You can find them on the web at http://www.saris.com/. I could only find one goldsprints club that used the CycleOps rollers. That was the KC Sprints group. I talked via email on Flickr with one of the guys from the KC Sprints group and they were happy with the CycleOps rollers. That made me feel better about the CycleOps system as a possibility. They sell an aluminum roller setup for $279.00. Their produce page is at http://www.saris.com/p-334-aluminum-rollers.aspx.

CycleOps Rollers

The drums on the CycleOps system I am looking at are aluminum which are a must for proper goldsprints. They feature 3.5 inch diameter rollers. This is the smallest size drums I would want to use for goldsprints. My local bike shop carries the CycleOps so that is a plus. I always try to buy local if I can. After going down to Rassy’s this weekend and getting my hands on them the frame is more solid that I was expecting. The drums where just okay. I was expecting the drums to be heavier. But overall I was impressed. I also need to pick up a fork stand and they runs another $99. Overall I was impressed with the price and the quality of the CycleOps brand.

My second and third options are from Kreitler. Kreitler is the standard when it comes to goldsprints and serious trainers. The specific Kreitler rollers I am looking at are the Challenger 4.5 with the Poly end caps.

Keritler Challenger 4.5

The drums on the Kreitler Challenger 4.5 system are a full inch bigger in diameter then the CycleOps rollers. Quality is top notch but you also pay a little more for them. The Challenger 4.5 with the Poly end caps is $389 retail but I have found them for as low as $329 out of a bike shop in Chicago. That is a really nice price. I will also need to get a fork stand for an additional $99. This brings the price up to just under $500. I know quality on the Kreitler is the best that you can find so the price is warranted in my opinion. I really like the larger 4.5 inch drums as well.

The last option is again from Kreitler. It is their goldsprint dedicated setup. It cost $999 plus shipping.

Kreitler Goldsprint System

This is a dedicated system build by Kreitler specifically fro goldsprint events. Both bike units are attached for more stability. But despite the quality this systems has a disadvantage in my opinion. You can’t train on this system unless you want to use the fork stands all the time. There is no third roller or even a way to use a third roller if I wanted to. That for me is a major disadvantage. When I am training I don’t want to use the fork stand. I know that for sure. The other thing is that I need to shell out the full $999 right from the start. I can’t just buy each single bike system as needed. I have to buy the system two bikes at a time. It is about the same price as getting two Challenger 4.5 systems so there is not additional cost in that respect.

And the Envelope Please…

UPDATE: I made one last ditch to get some feedback on the CycleOps rollers. I found out that the Black & Gold crew are using the CycleOps setup with no regrets. Also, the grew down in the Kansas City area are using them with great results. So I have had a change of mind and deciding to go with the CycleOps. Here is why:

  1. I can buy one unit at a time.
  2. Feedback from other using them has been very positive. They have been doing goldsprints for years and they would buy the CycleOps setup again.
  3. I can train on this unit with all three rollers. Then when I want run the goldsprint events, I can put the fork stand on.
  4. The CycleOps setup is a little less expensive than the Kreitlers. I based on feedback I don’t think I am sacrifising anything with the CycleOps.
  5. I will be supporting my local bike shop by going with the CycleOps. I am hoping they become a sponsor as well.

The disadvantage is that I will have to build a box for each roller eventually. This adds to the stability of the system. A few 2×4′s and some plywood and it is an easy enough task.

So by next weekend I hope to be testing Goldsprints FX with a roller system. Make sure you check back for the results and a video of two next weekend. If you are reading this and have another suggestion I would love to hear it! Please post a comment.
