Bamboo Tubular Rims – Test Protocol by Edgar Jakobs

We are pleased to present our new addition to our bamboo rims line, tubular rims.

Our Thanks to Edgar Jakobs, Germany, for his unique and great work.

Testing Ghisallo Bamboo rims Tubular – Protocol Stuhr / Germany, 28. September 2013

Hello again Cyclists,

when I finished the 500km Testing of the Ghisallo Bamboo rims for Clincher Tires I was asked by the Ghisallo Team “What about a Test of Ghisallo Bamboo rims for Tubular Tires?”. I said “Yeah, how we gonna do that?”. They had already manufactured a pair of them, Tipo Elegant with 32 holes and I received the rims a few days later.

In 2009 I mounted a wheelset with these rims made with beechwood for a Touring Bike, the GILCO 60G. So I knew the rim diameter and the spokes were in the house.
I used DT-SWISS Competition Spokes on the rear wheel, right side (3x) and DT-SWISS Revolution Spokes on the rear wheel, left side (2x) and on the front wheel (2x). Nipples are the 2mm Brass Version, Hubs are Campagnolo Record.

Before I mounted the rims I carried out a visual inspection. Everything was okay, no splittering on the holes and a very beautiful finish with clear coat.
The first step was to put the nipples with the washers into the spoke holes. The size of the holes fits exactly to the nipples, so they don’t fall out of the rims overhead.
With a little grease on the threads of the spokes I mounted the wheels without problems.

After the wheel building was done I bought tires with removable valves and tapes to fix them on the rims. Here you can see the Installation of the tape and how to use the sealant:

I used the original brake pads from Ghisallo in yellow colour. A little stripe is visible on the rims, that is art! But, more important, the soft pads do not damage the surfaces of the rims! I clean the rims from time to time with warm water and washing up liquid. A little turpentine is allowed, but is not always necessary.

After 200km I made a little service to tighten the spoke tension.

Now, after ca. 500km, I can say the Bamboo rims for Tubular Tires are a good opportunity for building light wheels. The rims weight is 360g, the weight of the complete wheels (incl. Quick release) are 750g (front wheel) and 910g (rear wheel).
Compared with the wheels for Clincher Tires including the tires the difference is dramatic: 1030g for the Tubular front wheel to 1490g for the Clincher front wheel.

So for many Racing cyclists the tubular system is the better solution, and this is also my opinion. Apart from the weight the riding comfort is higher than on wheels with Clincher Rims.
But the clincher rims with Ultimate Optional are easier to mount. And it is possible to use rugged tires, maybe for Touring Bicycles. I recommend this rims to mechanics who want to build their first wheel set with Wooden / Bamboo rims.
Bamboo is an alternative for the construction of rims!
