Polygon Siskiu D6 Upgrades that really improve the bike!

[@rgmtb]

-- HERE'S A KIT WITH ALL MY UPGRADES -- kit.co/rgmtb/my-polygon-siskiu-d6-upgade-list

[@SW-Video]

What was the total cost of the upgrades you did to this new bike?

[@grandad5443]

I love what you have to say , and the way you say it . I have just ordered a Siskiu D7 SE which has Boost forks , much thanks to you for bringing this to my attention.

[@richarde1355]

My D6 upgrades: Raceface grips Chester pedals Maxxis Assegai 29x2.5 tires SLX front brakes with 200mm rotor Rockshox Pike fork Works great! Next upgrades, PNW Loam dropper lever, frame protection, fenders, and another set of wheels (for light trail use). Great bikes!!

[@JasonFoxLCB]

Very nice. I got a D7 a couple months ago and did similar things (minus the fork). PNW Range bar, slight riser stem, Loam dropper lever, helicopter tape, new tires (tubeless). Digging the bike so far. Hard to beat for the price and, well, actually being in stock.

[@fengcarlos]

Can you fit a 29 x 2.6 tire in the rear?

[@thim8009]

On my n9 I double face tape a bottle cage on outside of down tube and use straps to hold in place then I can use up to a liter bottle.

[@humanresources3545]

I bought an xtrada 5 (hardtail 2x10) late last year. I changed the pedals and grips. I'm happy with the seat. The front fork is SR Suntour coil spring. It wasn't lubed and the preload adjuster was damaged. I lubed it and have ordered a new adjuster. I also am trying to get a softer spring. I was starting to give it a bit too much of a hard time on rough trails so I recently got a T8. The pedals seem OK. The grips are OK but I might get some of your lizard skin north shore lock ons. The seat is a bit harder than the Xtrada seat - I'll see if I get used to it. The bars are flat bars - same as on the Xtrada - I've ordered 25mm rise bars. I spent a few hours playing with the suspension settings using the Fox guides.

[@gabrieldenoury5863]

Buying a new fork and wheels would have cost you more than the price difference with a D7 SE which comes with a better boost fork. Bought one a few weeks ago over a D6 for that reason and happy to be riding my stock bike!

[@mtbboy1993]

Pretty sweet build, but I would add an oval chainring and a bash guide. And out other mudguards on, I prefer Mudhugger.

[@MTB_FANATIC99]

Like I said my other comment I'm ordering the D6 SE and they added a boost fork it's not a Air fork but it's still boost spacing 👍🏻👍🏻👍🏻👍🏻

[@rgmtb]

Totally agree! Even if the fork is not stellar, having the boost spacing and not having to buy a new front wheel if you choose to upgrade the fork is worth it! Nice dude! I really hope you enjoy your new bike!!!

[@richarde1355]

Hey, Gene, do you know the size of the rear shock? 190x45, perhaps? I can’t find the info online. Thanks!

[@MTB_FANATIC99]

I'm thinking about ordering the polygon siskiu D6SE One question I have is the front and rear suspension upgradable cuz I will do that eventually?? I'm really interested in the bike I was going to order it on the 20th of this month November EDIT I COMMENTED AS THE VIDEO WENT ON AND I MADE THIS COMMENT BEFORE I SEEN YOU CHANGED OUT THE FORKS BUT THE D6 SE THE ONE I'M GOING TO ORDER COMES WITH A BOOST FORK UP FRONT WITH BOOST SPACING

[@JamesRobertMTB]

Love the colour scheme of this!! Haven’t seen anything similar to this 😍

[@richarde1355]

Beautiful bike! The Siskiu offers a lot value. Somewhat of a silly question; to the extent the front hub is non-boost, is it safe to assume the rear hub is also non-boost?

[@fengcarlos]

What is the weight after the upgrades?

[@arty5034]

I’m in Australia and finding it hard to find non boost forks to upgrade my D6. I see your later video with the non boost to boost upgrade kit, but wondering if you (or anybody else) knows some non boost, tapered fork options better than the stock fork? I've seen some but the offset is 44mm, as opposed to 51mm for the stock fork - not sure if that would effect the geometry negatively though.

[@Drama-tm4jx]

Hey did anyone know if he had to change the headset to fit the new form or was it the same headset that came with the fork?

[@rgmtb]

Same headset 👍

[@Drama-tm4jx]

@@rgmtb thanks so much !

[@bobvelting379]

if you realy want to run a boost fork with a non boost centerlock hub you can still use a adaptor kit with a 6 bolt rotor that bolts straight to your centerlock 100mm spacing hub. these kits should be about 20 dollars.

[@rgmtb]

Yep! But this was the only one I could find. kzbin.info/www/bejne/b3bNq2Cdl9SBm9U

[@Mytro34]

I cant decide between the D6 & D7. The only thing i know for sure on both ill be doing us going tubeless

[@rgmtb]

I'm loving my D6 but would go for the D7. Here's the thing, the lack of the big gears on the D6 is a bummer. The D6 will need a few upgrades but the D7 is pretty good out of the box 👍 If this info helped would you please use my link when you end up getting a bike. It's a huge help man! Let me know if you have more questions.

[@Mytro34]

@@rgmtb 100%. Just found your links and I am loving your content and you as a person and your video style. Extremely helpful and broken down for everyone. Gladly will!

[@willis17191]

What non boost 140mm fork would you suggest?

[@victorolmos9047]

Hi, my rear shock broke, I want to upgrade to the one you have but I don't really know much about suspension, I was trying to get the same specifications as the shock you have but I can't find it on the description. Would you be so kind to let me know the exact measurements so I can buy it

[@phlr]

Hey Gene. Thanks for the content. I just got a 2021 D7 and was wondering about the back wheel. So you talk in your video that for the front you needed a new wheel to accommodate your new fork. But it wasnt super clear about the rear. Does the rear on this frame have enough space for a boost wheel? Thanks

[@huskerfan3352]

Yes the d7 comes with a boost rear just not the front

[@rgmtb]

100% correct and thank you for responding @azmtbbeast. The rear is already boost and does not need to be changed.

[@phlr]

Thanks for the replies. With that info and your video about the convertion kit for the wheels now I feel like my budget full suspension has a lot of potential

[@rgmtb]

@@phlr Totally!!! You bought a great bike and have a lot of fun times ahead of you 👍

[@superyamagucci]

Bubbles in film: mix up dish washing liquid in water, about as soapy as you’d do dishes with. Spray both frame and film so they’re soaked. Apply and wipe bubbles out with cloth. Easy. Also do this for any decals, phone skins etc - let’s you slide them round for perfect alignment too.

[@rgmtb]

I would agree with you big time but the company that makes these frame stickers said to put them on dry. Trust me, I agree but I was just following the instructions.

[@superyamagucci]

@@rgmtb Unless it’s paper, put it on wet. I’ve been doing vehicles and machinery this way for over 12 years, never had a problem.

[@superyamagucci]

@@rgmtb Oh also should mention, I’ve seen a couple of your vids on this bike. Decided it’s a good first mtb for my 11yo. It’s going to be a little large for him for a start, but I’m not going to get him a new bike every time he needs a new pair of shoes, and 27.5 was good enough for me, so it’s good enough for him ha ha PLUS he gets suspension - we just got snow in summer and uphill both ways…

[@seojayden2053]

Thinking to buy secondhand Polygon siskiu d6 2018 vs. GT avalanche expert 2014 vs. Giant fathom 29 2 2017. Which one would be the best choice if its conditions and prices are same. Please help me any advice and suggestions? Thanks!

[@rgmtb]

Answered this for you on your other post

[@tysonm2525]

Did you find the sizing to be accurate? I’m 5 11 and I’m wondering whether to go with the medium, what are your thoughts?

[@flyingtigers7856]

Great vids, thanks for your hard work! Quick question please, the D6 fork, how would it compare to an even lower end coil fork? For example, even though the fork on the D6 is not great, is it still a step up from a Suntour XCR 32 coil with 120mm of travel found on some Polygon hardtails? Keep the party on the pedals!!

[@rgmtb]

Good question. The stock fork is certainly better than those coil forks. It might not be great but it's better than those.

[@flyingtigers7856]

@@rgmtb Reading between the lines on reviews I suspected it would be, I'm going to pull the trigger on a D6 soon. Thank you for replying, it's really really appreciated!!

[@thedoghouseoutdoors4116]

So I just got a d6, and I was looking over your upgrades, and the wheels, it don’t looks like your shop where u got them from has the anymore, any other places u would recommend to get them or even any other wheels to get?

[@rgmtb]

Supply has been tough. Let me ask you this first, why do you want to upgrade them? That would help me direct you to another set.

[@mikieson]

i might be wrong here..but you probably could have bought the next model up or even better by the time you upgraded? AND since you didnt do it over a LONG period of time making it maybe more cost effective ?? I know upgrading is fun though :) but it was something i was just thinking when watching. Im glad you got it how you want though. NOW i wanna see some trails! I wanna see you getting RAD!! lol..yeahbuddy!!!!

[@chrisjones7281]

Sometimes that IS true, however I too picked the D6 over the D7 because even though it had better spec, the parts it had also I would upgrade. The same with the T7. The Recon fork on those bikes has steel stanchion and is very heavy while only being a little better than the suntour on the D6. If you don't plan to do upgrades then starting with the better model makes the most sense 👌 .Otherwise lower the cost of entry and build how you like😎

[@LaredoHandyman]

I'm guessing you spent a thousand on upgrades. Couldn't you have just bought a $2500 bike that was already to your standard? I just ordered this bike. I have very little experience on modern mountain bikes so I hope I'm happy with the forks on this one. Tires and pedals etc. I don't mind upgrading if needed.. Great channel btw!

[@reeveharper8424]

So you want from an 120mm fork to an 140mm fork. Has that had any negative effects with the geometry

[@rgmtb]

No not at all. The bike is spec'd for a fork of this length so it's all good.

[@reeveharper8424]

@@rgmtb Awesome, I thought it came with a 120mm fork though? So does this rake the bike out a bit?

[@etofoya8217]

My d7 shifts slow. I need it to be more smooth. So I can get my speed up. Cassette and derailor upgrades I would like . Any good brands.

[@rgmtb]

Personally I'm a Box Components fan. Here's an affiliate link boxbmx.com/?ref=ra5c3s4fyghk and I think my code will still offer you a discount rgmtb15 if you find anything you want to buy ;-)

[@bearish_benzino9941]

Any thoughts on upgrading the front and rear shock to 150mm granted the bike’s angles?

[@rgmtb]

The rear can not be upgraded to any more travel than it is. This is a frame design thing and that is the limiting factor. As for the fork, 150 is really to much travel for this frame. I'm not saying you technically can not put a fork with that travel on this bike but it's just not right. If you are looking for this kind of travel you should look at the T or N line bikes.

[@wifimtbvlog1206]

which one better cannondale habit 5 or polygon?

[@andresmtb9284]

Hi I have a d7, is it possible to up the travel on the rear shock

[@rgmtb]

Nope. The rear travel can not be changed. Sorry man.

[@fengcarlos]

Thanks for the video, Can you fit a 29 x 2.6 tire in the rear?

[@rgmtb]

That might be a bit tight. It would really depend on the tread. I'm confident with 2.5 but a 2.6 with wide knobs on the side might be pushing it. I will say that there is WAY more room than most bikes. Also, the 29 pushes things out some so it's gonna be a tight 2.6 fit. Sorry I can't give you a sold on that one.

[@fengcarlos]

@@rgmtb Actually thanks for taking the time to response. I ordered the bike but I really want to fit a Rekon 2.6 in the back. But if I cant its not a big deal.

[@Chriswillrise]

Do you know of anywhere that has all the manuals for this bike and suspension online? I bought one used but it’s so hard to find info it seems like they are trying to get rid of this bike

[@rgmtb]

The bike is still listed on the AU site www.bicyclesonline.com.au/2021-polygon-siskiu-d6-dual-suspension-mountain-bi It should be back up on the US site towards the end of the year. Right now it's just a stock thing but the bike has not be discontinued.

[@Smegma_pirate]

I like your honesty : “ I put a suntour shock on my bike because suntour pays my bills” lol shill status=100

[@_Bryant.R]

What's the biggest rear tire that will fit?

[@rgmtb]

Ugh, this is always such a tough question to answer because the treads on each tire can vary so much. I would say with safety that you can get a 2.5 on the rear.

[@_Bryant.R]

@@rgmtb thanks for the reply and yeah didn't really think that one through before asking haha.

[@wanghenry9397]

Can I add a 150mm travel or 160mm travel on it?

[@rgmtb]

You'd really be pushing it with a 150 and a 160 is much to large.

[@wanghenry9397]

Thanks so much and it help me alot

[@thim8009]

Wonder if all the changes you did, if it adds up to a siskui n9 in price?

[@Smegma_pirate]

N9 is a completely different bike. Beefier frame and components.

[@ridwanabdullah9275]

Hi Gene, nice video, very informative and detailed. What size of Fidlock bottle are you using on the video? What is the biggest size that can fit your bike? Btw, what size is your Siskiu D6? 27.5" or 29" ?

[@rgmtb]

OK this question seems to come up a lot. I'm using the FIDLOCK Twist Bottle 450. The frame is a med with 29" wheels :-)

[@ridwanabdullah9275]

@@rgmtb thanks for the answer! Can it fit a bigger version of FIDLOCK? 590 if I'm not mistaken. Cheers!

[@teamhuber]

Which fender protector are you using on the D6? Looking for one for my D7 ;)

[@rgmtb]

So that one came with the fork. The D6 comes with a pretty low end fork so I upgraded to a Sr Suntour Axion. The fork on your D7 is pretty sweet out of the box so you're good to go.

[@rgmtb]

That being said, check out these guys for some cool stuff. I used their clear frame kit on my D6 groundkeepercustom.com/

[@bumblebeeyaj9375]

You should try Engro or PNW grips

[@rgmtb]

Funny you should mention that. So I'm not a fan of the Engro (though I have lots of friends that love um). They just don't feel good to me. The same for the PNW grips until now!!! PNW released their extra large grips and I love them! Exactly what I was looking for and recommend them big time.

[@md-le4nh]

is the d6 tubeless ready?

[@rgmtb]

The rims are tubeless ready but you still need to buy stems and possibly tires. I say possibly tires because there is a shortage of parts right now and I'm finding tires my differ on your bike. The ones sent with my bike where not tubeless tires so I needed to replace those too. That might not be the case with you.

[@gerrydillon8761]

Are you ready to sell this bike yet?

[@Howard9Fitness]

Shock is bad, i only road mine for 100-200 miles and it’s basically blown. I’m a bigger guy but still

Did you set it up correctly

[@miloscoopy2469]

The teacher is teaching ...LoL

[@LarryHopper]

Why not just buy the bike you really want?

[@rgmtb]

What do you mean? Nothing in life comes exactly the way you want it. There is no bike on the planet that is built with exactly the parts I would want. That's why aftermarket parts exist man.

[@LarryHopper]

@@rgmtb, I see. Thanks and enjoy your ride.

[@irishsavage8715]

I’d rather have the cheapest Rockshox over the most expensive suntour…. SunTour is pure garbage, and it will eventually leave you stuck
