The 1" Gorilla tape is almost a perfect fit for these rims.


The tape is almost exactly the same width as the channel, but since the bottom of the channel isn't flat there is a small gap (~1 mm) on each side.

I got the hubs ordered; should come one day next week.

I received the rims today.  The main delay was me deciding whether to build them myself or order a full wheel set-  I finally decided to try building them myself.  Peter shipped the next day, and EMS shipping took 8 days.

The rims weigh 405 and 410 g on my cheap hanging scale.  So far the plan is to build them up with DT Swiss 350 hubs and Revolution spokes.  After reading a bit, I'm leaning toward getting the hubs in and doing a spoke measurement before ordering a full set of spokes.

I guess not 

I'm looking at building the iPlay rims with DT Swiss 350 hubs, since they are available with centerlock mounts and are half the price of 240s for about a 2 ounces weight penalty.

Using the DT spoke calculator with an ERD of 597 mm, I get a range of 289 to 291 mm spoke length. Anyone want to double check for me, or does this sound correct?  Should I go with the 291 mm spokes for all of them (easier to buy one box)?  I assume having 2 mm sticking out inside the wheel won't touch anything, but will there be enough threads on the spoke if I use a 291 instead of 289?

Thanks!

Anyone have the Novatec 711/712 hubs, or would you suggest another set that Iplay uses in their wheels? 

The 056/057 frames use a 34.9 mm clamp on front der and the cable comes from the top.  Not sure about the size of the Goblin tube, but it is the same style front derailleur as the 056/057. 

The 256 has a direct mount front, and the cable comes from below which is different from the Goblin frame.  You could probably get it to work, but it is a different setup.

Looks like the Goblin also has a tapered headtube, so you should be OK there.  The small 056/057 and 256 are 105 mm long, but the other sizes are longer, up to 135 mm.  The Airborne page shows all Goblin sizes with a 110 mm headtube length and a couple of spacers, so as long as you didn't shorten the steer tube you should be OK.

The IP-256 drawing I got from iPlay doesn't show standover, but for the 056/057 it is 769, 805, and 826 mm or 30.3, 31.7, and 32.5 inches respectively.  I would like a bit more, but I haven't smacked my nads on the top tube yet.

I have the Necco headset that IPlay sells.  Some don't like it, but it works for me so far.

Cross country with obstacles.  I don't do anything you'd see in a video, but I do like some landmines in the trail to keep it interesting.  I also have a road bike, but if I had to choose I'd pick the mountain bike first. 

Could you make one with some aluminum shim stock-  cut out a rectangle and press it on to the frame to form it, then glue it on? 

DOH! Need to read a little closer...  At least they are shipping frames now.
