2019 Pro Bikegear Koryak Dropper Post


PRESS RELEASE: Pro Bikegear

July 8, 2018 – Broadening the range of Koryak high performance mountain bike dropper posts, PRO launches four new models ranging from 70mm to 170mm in travel and covering seat post diameters between 31.6mm and 27.2mm. Riders looking for a long travel post for enduro bikes, medium travel post for XC racing, or a short travel post for gravel riding can now experience the infinite smooth travel and reliability of the Koryak dropper range.

The Koryak 170mm features internal cable routing and provides a total length of 507mm for large riders. Both the 170mm and 150mm droppers are made from 3D forged lightweight AL2014 alloy and employ a 1-bolt clamp design to mount to the saddle. The 150mm offers both internal cable routing for the neatest setup or external routing for the faster set up, avoiding routing around the bottom bracket.

The lightweight, PRO Koryak 70mm dropper post can be used on XC or gravel bikes with 27.2mm seat post diameters where small drops in the saddle can make the difference between clearing a descent confidently or not at all.

All versions deliver smooth travel and come with a Shimano cable set allowing for adjustment at the dropper post lever. The 170mm and 150mm internally routed posts come with a new 1x left-hand lever whereas the 150mm and 70mm externally routed posts come with universal up/down levers for use with 1x or 2x drivetrains.

 One bolt. Does it come with friction paste too?

 Those type of seat clamps are not as bad as you think.

 @zyoungson: yeah... they're worse.

 Clamp design is a deal breaker.

 Talk after you have used one. I have a PRO Koryak post with this clamp system since a year and it hasn't skipped a beat. I weigh 95 kg and I am not exactly easy on bikes. Cheers!

@nuttypoolog I assume you have used one for a good while too and know the drill? Wink

 @Maxipedia: agree. I ran their road stuff on a CX bike for years, no issues. Pro (Shimano) makes good stuff. I'm over 200lbs and it didn't shift once.

 @atrokz: I think one thing you learn as you grow older is that efficiency and quality are more valuable than fancy shiznit. I have never been quite a fan of Shimano and I am a brand-sensitive guy who finds PRO pretty dull. But if I look at my bikes, there are Shimano brakes on pretty much all of them, recently a Shimano drivetrain on my enduro bike and PRO handlebars, seatposts and other bits where before there were parts from ”cooler” brands. I can't find any fault to what these guys are doing. Oh, and their seats are awesome and underrated. Smile Life is good when you ride and have less problems.

 @Maxipedia: I recently fitted one on my Camber 29er and regret it. The clamp is a bad design and continually squeaks, regardless of how tight it is. I'll get some friction paste but I see this as having to compensate for a poor design - it shouldn't be necessary. I'm only 80kg and not that aggressive a rider. There are so many other options on the market, just buy something else.

 So many good droppers on the market now that even a long travel version is met with crickets. These are good times for mountain bikes

 This needs repeating over and over again: “these are good times for mountain bikes”

 I have loved my koryak post for the past two seasons. Here are the things I love about it the most:
Cheap
never went squishy
return speed is not slow but not too fast
ability to lift the bike by the seat
Zero side to side play in the nose of my saddle after 2 seasons.
the clean looking clamp is awesome.

 Wait, it says, four new models. Only 3 are shown.
What I'm missing?

 @enrico650: 150 one in two variants - external or internal routing.

 Looks promising. My only concern is that the seat clamp doesn't seem to have much surface area on the lower part which might increase the risk for bent seat rails.

 That clamp design has been used by other brands, and always slips if you land hard on the saddle. I always want the trusty two bolts fore and aft design.

 My Trek Boone uses that style of clamp, the infinite adjustability is... Good I guess, but if you don't torque it to 14Nm it'll rotate, and even torqued to spec my saddle creeps back slowly with time. Next time I need to readjust the saddle position, I'm going to put some valve grinding compound on the Ti rails to hopefully add some traction to the clamp. I've tried carbon paste but it doesn't seem to hold well enough (the past helps with the rotation issue just not the saddle sliding)

 i have bent rails with shimano posts before of this design but its rare... new solution: carbon rails

 Couldn't be bothered to show the levers?

 Or the price or the weight?

 It's funny: Shimano released videos on how to replace the cartridge in these dropper posts...only you can't find the replacement cartridge anywhere. It's almost as if the intentionally hide the fact that the post can be fixed by the average home mechanic, maybe they just think we'll just go out and buy a new one?

 Part YPRSP0193, multiple sellers on Amazon, $55-$60 shipped.

 @JohanG: Hey thanks! Can that part also be used with some other Trans-X/Brand-X/PNW droppers?
  • 4 1
 Correct me if I'm wrong, but I thought koryak was just a rehashed Tranz-x/Brand-x dropper with a less reliable saddle clamp?
  • 3 1
 How could you confused Shimano with brand x?
  • 1 0
 Heard that as well... But I have brandx dropper and its fantastic considering the price
  • 2 5
 @yzedf: I wouldn't be surprised about this at all. Shimano outsources lots of stuff and sells it as their own. KMC doing most of their chains is a prime example.
  • 4 1
 Excuse my ignorance, but is Pro the same thing as Shimano?
  • 2 0
 Yes, it is.

 Ya, take a look at the pro cockpit stuff..its really lighweight and well sorted. I just got a tharsis stem and pro c. H-bar.

 One bolt saddle clamp.. never been a fan of those. Maybe these will be better then the ones ive used in the past

 I've had my saddle slip twice over two years from little G-outs while sitting down. Otherwise, never been an issue.

 Still no internal 100mm. I had a 120mm with 170mm to the saddle rails available but with the tallness of the collar it was too tall.

 Am I the only one who wants a Di2 model?

 What is the price??Was it mentioned?

 Dam such a shame. I was after a 171mm drop post so i supposed i will have to wait until it is invented!
