Free Radical on a Hardrock
 
UPS brought my Free Radical today. I mounted it on a Hard Rock Comp Disc. It took about 3 hours to mate it up and get everything adjusted. Took a break about an hour into it to run to JensenUSA and grab a 203mm rotor for the rear. The only problem was in mounting the yoke to the chainstays. There is a bridge which means you have to mount the bolt forward of the bridge as in the instructions. The problem with that is the bolt head interferes with my bottom pull Deore FD. The solution was to drill a 6 mm hole in the bridge for the bolt so I could move it back to clear the FD.

It took about 5 miles to get used to the ride. I ride every day so I know exactly how my bike sounds and feels over every kind of terrain. It's a 4000 mile/year work bike that I use daily in the research orchards where I work. But once I recalibrated myself, it's fine. It has the frame resilience of my Rans V2 LWB, but it still handles the rough stuff like the Hardrock it still is.

It's been a good pickup truck for the field. Now it's going to be a great one!

There are some pictures on Flickr of people whose chainstays end up flattened after drilling like that, but the chainstay bridge in that case also looks like the owner had let it rust too much, so it could have simply been neglect.

I emailed Xtracycle about it when I was doing mine and faced a similar problem (but that was that the chainstay bridge was actually too far away to get the bolt on the other side), and they said its just fine to have the bolt *before* the bridge as long as it still sits snug. Hopefully your solution will work out well for you though, and congratulations on the 'X!

I bought two of the aluminum front attachment plates since I didn't know what the problems might be going in. I was concerned about drilling the bridge as well, but decided it would be a good idea anyway as it would help center the bolt and keep it there. Tightening the bolt didn't flatten the bridge, but just in case, I think I'll use the extra attachment plate on TOP of the chainstays, and still run the bolt down through the bridge. This will take the pressure off the bridge, but still allow it to locate the bolt and hold it centered in place.

At least half of my daily mileage is on dirt roads and some of it is riding down irrigation furrows in the citrus groves where I work. Should be a pretty good test of the durability of the Xtracycle.:D

Thanks for the comments.

You wouldn't happen to have a photo, would you?

I attached a photo of the whole rig. Did you mean a photo of the problem area?
