I was wondering what the major disadvantages and disadvantages are to 2mmtru axles vs classic drops. I have an 8inch front rotor and im running it on some old crappy Judy XLC that i got for free. Im looking to upgrade the fork and im seeing many good deals on Jr Ts etc with drops. Im haveing trouble deciding what to to.
Thanks in advance.

20mm will offer more support making the fork stiffer and will be able to handle harder hits. You will also get a quicker response when turning.
The JR T has qr not a through axel.
The Jr T has a 20mm QR and they have made the dropouts very easy to use. You used to have to use an allen wrench to remove the axel but now you just flip the levers on the bottom and out it comes.
I say get the fork.

Whoa...im confused. Does the capitilazation of the letters designate between the forks. Are you suggestion i get the Jr T with the classic dropout?
Thanks

If you are going to upgrade to the Jr T I would say get it with a 20mm qr rather then a regular qr (if you can afford it). If you realy need a new fork now and can not save a little more for the 200mm then get the jr t.
Remember, the Jr T is a freeride/dh fork and is not a very good xc fork. If you are looking for a fork that will let you climb as well as handle the drops and jumps then look into the Z1 series.

I'm running a RS Psylo SL w/ the Tullio 20 mm front end.
I didn't think a 20mm thru axle would be any different. Wow, was I wrong. The thru axle makes the front end super stiff. I'll probably never go back.
There are a few things to consider though.
1) Added weight. Not a big deal if you're looking at a fork like the JR T.
2) Not compatible with many fork mount racks, unless you get an adapter.
3) Less availability of wheelsets, especially used ones!
4) Cost, not really an issue since the stiffness is worth the $$$$.
I've built my bike (Intense Uzzi SL) as a freeride machine with Mavic D321 rims (Heavy). My buddy wants me to race in a 12-hour race, and I want to use a lighter weight set of wheels, so I'm not totally dead after just one lap. In order for me to do this, I have to buy a new hub and build a new front wheel. No one makes a 20mm hub laced to a lightweight rim. Not inexpensively anyways. So, I'll probably have to spend a lot of money on an extra wheel I'll rarely use.
Just something to consider!

I love my 20mm on my fork! especially if you're gonna run a 8inch rotor! That causes alot of torque on the legs, the 20mm takes it all away. You will notice a difference all around in the stiffness of the fork! Everyone else has told you all the other stuff...so that's it. :crash:
