New 384gm Kinlin Niobium 22mm Clincher Rim

[Marcus Torino]

I worked out it would be possible to build a sub1200gm set of clincher wheels with these! :eek:

[soulspinner]

Tune hubs and skewers, Sapim x-ray spokes?

[Marcus Torino]

Tune hubs and skewers, Sapim x-ray spokes?

I figured Extralite hubs.

[93legendti]

Jeremy will have the skinny on these rims.

Tune hubs and skewers, Sapim x-ray spokes?

I don't think that wheels weights usually include the skewers.

I have a set of wheels built by Jeremy with Tune hubs, Sapim CX-Ray spokes, and Kinlin Niobium XR-270 27 mm 28/24 rims. Those rims weigh approximately 430 grams. The wheels weigh approximately 1390 grams, per Jeremy. If you were to use the above with the 22 mm Niobium rims you mentioned, then you could save 430-384= 46 grams per wheel. That would save you 92 grams for the set. 1390-92= 1298. Hence, you already have sub 1300 gram wheels (slightly). I would imagine that Jeremy or ergott, who also builds with the Niobium rims, could get you to sub 1200 grams if that is what you want. Both build excellent wheels.

What are the specifics?!

I'm interested in finding out more about them, and I'm having a hard time seeing how this picture is of a 22 MM deep rim unless the machined brake surface is very narrow.

I have a set of wheles built by Jeremy with Tune hubs, Sapim CX-Ray spokes, and Kinlin Niobium XR-270 27 mm 28/24 rims. Those rims weigh approximately 430 grams. The wheels weigh approximately 1390 grams, per Jeremy. If you were to use the above with the 22 mm Niobium rims you mentioned, then you could save 430-384= 46 grams per wheel.

I need a set of those...

I have 2 sets built for me by Troy from Ligero Wheelworks. One Campy and the other Shimano. The Shimano weighed in at EXACTLY 1290 grams for the pair without the Tune Skewers. They are used daily and switched between my Ottrott and Ulteam. Very nice set.

[Marcus Torino]

What are the specifics?!

Extralite hubs, CX-Ray or Aerolite spokes and alloy nipples, 24h front, 28h rear. I'm thinking I'll soon have a set... :confused:

[ergott]

I'm waiting to see actual weights. The 19mm niobium rims are around 400-410g so I don't see how higher profile rims will be lighter from the same company using the same alloy. The other rims from Kinlin are known to be a bit over advertised weights.

[Marcus Torino]

ergott; perhaps because it's the first batch? No tool wear yet...

I'm assured the weight is correct, I'll have a set later in the week and I'll confirm it.

[ergott]

I didn't know you weighed them. Nice. Let me/us know how they build up. Crostini rims are around 395g and I wouldn't recommend them for rear rims unless the rider is real light. Not sure how a lighter, higher profile rim will be better. I like niobium rims so I would like to see more about them. The distributor will have them in the next two weeks or so.

[Marcus Torino]

Next two weeks? They are already available here.

This store has them built on 240s hubs for a pretty good price; http://www.sales.light-bikes.com/

That gets you to 1233g, and that's being quite generous reg. the rim weight. In reality you'd probably end up 1250g+?! Also I'd make a different choice reg. hubs.

[ergott]

There's only one distributor in the US for Kinlin rims that I know of. That's Alchemy Bicycle Works. I'd be curious as to where this place is getting them.

[ergott]

There's no mention of them selling rims separate. Where did you get your rims?

[Marcus Torino]

Marcus, do you have other pictures of these rims, or a link to the manufacturer? I'm interested in finding out more about them, and I'm having a hard time seeing how this picture is of a 22 MM deep rim unless the machined brake surface is very narrow.

It's 9mm wide in the brake track. Here is a close up pic

[Tobias]

Thanks Marcus. It must be an optical illusion because the first rim looks to me like it is about 30 MM deep or more. This last picture looks much more like what I would expect. Nice looking rim.

[RPS]

Anyone know the rim's width?
Is it extra narrow to get the weight down?

[Marcus Torino]

18.2mm

[RPS]

It looks very similar to the Velocity Fusion except slightly scaled down.
At about 100 grams lighter I'm guessing it's meant for lighter riders.
At my size these may work well for my next bike. The Fusion is overkill.
Do you know how long they have been in use?

[Jeremy]

Hi All,

The Kinlin XR-200 is now here. I weighed a sample of 10 rims. The range was 376g-384g. They look very nice, and I suspect that they will be very strong for the weight. Actual measurements are 18.3mm wide by 22mm deep.

Cheers,
Jeremy

[RPS]

They look very nice, and I suspect that they will be very strong for the weight.Thanks for the update Jeremy.
Is there a ball-park spoke count recommendation for a 150-pound rider?
I know it varies by rider, bike, desired durability, etc.
Just a rough estimate to help visualize how they would look is appreciated.
Thanks,
Rick

As you say, needs/requirements vary from person to person, however I think that a 28/24 build should work well.

Cheers,
Jeremy

[Marcus Torino]

My set is 24/28h and I'm 195lbs, no ride report yet :crap:

[Tobias]

Do manufacturers list the moment of inertia for rim cross sections or some other type of information that allows comparison with other rims? Other than weight that is.

It would be nice to see how these rims compare in stiffness to Open Pros or other popular rims.

[Marcus Torino]

There's only one distributor in the US for Kinlin rims that I know of. That's Alchemy Bicycle Works. I'd be curious as to where this place is getting them.

Last count (by me) there are five distributors.

[ecl2k]

besides sounding more delicious, how does the alex crostini 3.1 clincher compare to the kinlin 22mm rim?
