We did a short, advance production run of 50mm Clincher , 32hole rim blanks. I've had several people ask me about these, and based on some prototype versions, I decided to go ahead and make a few.
Rim weight itself is same as our other standard rim (not SL) of about 400gr. Which is still very light for a 50mm rim. ( I just weighed it at 438gr)
It's centerline drilled with DS polarity - so you can use the same rim for either front or back - but nipple bed is reinforced and designed on the DS to accept higher torque. The first set is for external nipples - considering most people will be using these under harsh conditions, external is just easier to service.
Why 32hole? Well, there are alot of riders - especially in the TCC, who are over 75kg , and ride long and hard under many conditions. Quite frankly, 24h , 20h (and less) is great for lightweight riders or event conditions - but, for larger rider and / or more severe use, they start to become a problem.
Anyway - I'm announcing them here first. And, as always, TCC'ers get a very special discount.
Recommended builds:
1) 'The MIke Watt' - Ultegra 'Jam Econo' hubs, Sapim Race spokes, Polyax nipples.
2) The 'Fred Flames' - Dura Ace hubs, Pillar Fat Boys, Polyax nipples.
3) The 'Wesley' - Alchemy Hubs, Sapim CX, Polyax nipples.
For CX use -- these would be awesome with DASH Monica, Sapim CX-Ray (rear) and Pillar Ti (front).
Of course - I can also build them with Dynamo front hub. This would result in pretty much the ultimate Audax / Randonneur wheel. Combined with discbrake - and wow - still very light!
By using more spokes - I can reduce overall spoke tension AND increase reliability. Combined with a stiff, yet good vibration absorbtion of carbon, the result is a very smooth and responsive ride. 50mm aerodynamics are so much better than narrow rim that it's hard not to notice the difference under any wind condition. If you are a strong(er) rider and regularly push into the 35kph+ range, then you'll know exactly what I mean. For endurance riding, being able to shave a few watts off your average effort is the difference between recovering to ride tomorrow and a death spiral to bonkville.
Specs:
Construction: Torayca T-700 /T-1000 High modulus fiber w/ Toray resins. Aramid reinforcement.
Finish: 3K 'Matte'
Drilling: 32hole - Driveside Polarity
Weight: 425gr Nominal
Tire Fitting: Clincher , tube-type.
