Polygon Siskiu D5 vs D6 vs D7 | Full Range Review (Beginner, Intermediate & Advanced Perspectives)

[@SChristopherBurford]

I have never ridden a mountain bike and am convinced I need the N9 to match the sick skills I throw down inside my own head.

I have 2022 D7. I'm 50 and ridden hard tails mostly so the D7 is a big change for me. I consider my self a novice. I do not regret buying it but It is forcing me to improve as a rider to get the most out of the bike. The D7 is the first bike I have owned that I've enjoyed climbing up trails. So easy.

[@mid-lifemission5825]

I've built a D5 frame up with parts from my parts bin as a cheap trail bike and its my favourite bike all round! Ive got a intense and a anthem gathering dust in my garage now as the D5 is so much fun to ride

[@Bazerca]

Love my D7!! Coming from an old 26inch 2003 duel Sus bike and having the previous experience riding, made me sway towards the better package overall of the D7. Has been easy to also upgrade anything I have needed over the past few years of owning it too!

[@bikesonline]

Right on! Sounds like you were the perfect candidate for the D7 based on what we felt! Great to hear you have loved it!

[@markmtbrider]

Why didn't you get the t8?

[@markmtbrider]

I am stuck between the t8 and the D7.....no D8 ?

[@RunBikeMike]

Polygon is definitely a brand I want to try out this year.

[@BrodieDavey13]

I was thinking about getting a D6 and this definitely gave me more reason too

[@bikesonline]

Great to hear it helped!

[@nmadero98]

I have a D7, I got if after riding a shitty hard tail for a long time. Awesome bike, your analysis was spot on

[@devanvanvliet3522]

I can't wait to continue to ride my D5! Finally some sun in Sydney... time to hit the trails.

[@bikesonline]

Keen to see you next video with Scott on a dual sus!

[@richarde1355]

I am so jacked! I bought a great shape 2021 D6 with upgraded fork (Rockshox Pike), Chester pedals, Raceface grips, Maxxis Assegai 29x2.5 tires mounted tubeless, the front brake an SLX with 200 rotor. It is a stupid crazy value.

[@bikesonline]

That's some solid upgrades!

[@bikesonline]

Having trouble deciding between a D7 and T7? Check out this vid kzbin.info/www/bejne/iXuVpKmKjKugmJo

[@vlbz]

D6 and D7 both look great, but I'm not getting a bike without through axles again. It flexed everywhere. Rough terrain, braking and so on.

[@bikesonline]

Through axles are a must for me when it starts to get rough so it would be the D6 and D7 for you! On the flowy stuff we didnt notice it too much

[@kap8608]

I'm confused my d7 came with through axles and better brakes

[@bikesonline]

You are right the D7 comes with Through axles

[@vlbz]

@@kap8608 I was talking about the D5 not having the through axle. So the choice should definitely be between the 6 and 7.

[@jimboyhizon2427]

I have D7 and I just assembled it. Looks awesome. I've been using hardtail since 80s lol...

[@bikesonline]

Nice!

[@colinl2908]

Definitely through axles., so 6 or 7 for me. D5 if want to have fun upgrading as you go.

[@bikesonline]

100%!

[@illwillmtb]

I would love to get the D7.🔥🔥

[@Justmyopinionlol]

I want d7 with 2x10 drive train as it is a great bike for commuting with occasional trails. For anything with serious downhill I prefer electric because pedaling uphill is so AD 2010 😂

[@richarde1355]

D7 with a 2x10? What year is your bike?

[@bikesonline]

That's something you could definitely add to a D7! The frame has a mount for a front derailleur.

[@HaIPeHaOP]

I'm only watching this because I already ordered a D7 and can't wait to try it out 🤣

[@bikesonline]

Hope you're enjoying that D7!

[@HaIPeHaOP]

@@bikesonline sure am! It’s amazing bike! Such a good value for money!

[@YoungBoom3r]

Kinda torn between the D7 and T7. Would love a comparison if they are even comparable? I know the T7 has better components, but which one is better for uphill? Seems the D7 would be better going up and the T7 would be better going down.

[@bikesonline]

We will definitely do that video soon! The specs aren't too different, only really the 11vs12 speed but the gear range is almost identical (11-51t vs 10-51t) and slightly different brakes. You are pretty spot on, the D7 will be better on the ups and T7 better on the downs. If you trails are lots of ups and downs and aren't to technical with, the D7 will be the better choice. But if there are a few more drops, rock gardens and fast open sections, the T7 will be better.

[@And3rs88]

I have the 22' D7 and another guy at the mtb Park has the T7, they are extremely similar and we both hit the flowy downhill jump tracks, but I would agree his shines a tiny bit more downhill VS mine uphill. Big drops or case a jump and the 140mm fork can soak it up slightly better when things don't go to plan. So much time is spent climbing too though plus the colour of the D7 just spoke to me. I didn't love the brakes at first so I upgraded rotors +20mm and using sintered pads (pads made the biggest difference), now they are awesome. Really don't feel the need to upgrade anything else!

[@westoversoutheast]

My wife has the D7 27.5 medium and I have the T7 29 medium. We are novice at best but after a year of riding, I really like her bike for just mellow trail riding and mine for confidence inspiring steep descents. The 29 wheels probably play a large roll in that as well.

[@ftrujillomunizaga]

I have an XC trek hardtail and a big enduro mondraker full sus, and the D6 I tried blew me away, the D series is definetely what 90% of mtbkers need, you can punish them like crazy and the price is unbeatable what you save you can use it to upgrade.

[@bikesonline]

Glad you agree! Thank you for sharing!

[@squadhouse1215]

[@shadowofthestarsdespair]

i just bought a 2023 d6 and idk what color its is cus BO has a difrent pictuer then polygons home page....o welll ill just wait to buy pedals that match

[@bikesonline]

Hope you got it sorted!

[@ariskardas]

I’m trigger ready for a siskiu D7 and the only thing holding me back is online comments in regards to the combination of my weight and low BB height. Can the shock be tuned to appropriate sag with a 115kg rider on a size large? Or should I bebe prepared to shop for a shock right from the start?

[@bikesonline]

The Low BB is definitely a blessing on the turns but there is obviously the potential for increased pedal strikes on technical climbs but timing can mitigate this a fair bit. You can always run shorter cranks in the future too. The bike is fine for your weight too, with the fork pumped up to the recommended pressure and running around 25% sag in the rear you should be fine but you can always put larger volume spacers in the rear shock if needed.

[@nasosnasos8054]

Love love love

got T8... me heavy rider.

[@markmtbrider]

How is the T8 going ?

[@aldrinclementina4297]

Hi there. Just a little bit about myself : I'm more than a roadie than a mountain biker. I've ridden Mountain bike since 2015. But know I'm doing it again, combining it with road bike. But I'll do it when the road bike season is over. What I did this year was starting with mountain biking. I've upgraded my Giant carbon XTC3 ("26) to fit the needs. But I'm looking for something more modern, full suspension and not worrying about the weight that much. Question: Which of these do you guys recommend me? Or do I have to go for the C5? Although it isn't a full sus. I can't tell that the "T" in the Giant XTC stands for trial. I do Cross country The fact that I'm not a full time mountain biker , but want to enjoy the moment I'm doing it, which one do I need to pick? Thanks in advance ✌🏽

[@bikesonline]

You would likely get along best with our Siskiu D series, but it may be worth the change in geo / attitude of the Siskiu T. Once you get to know it, it may suit you better and bring more joy in a dedicated MTB arena.

[@holliedekraai4137]

Would you recommend a d6 for a beginner mountain biker? I’ve looked at the polygon xtrada 7 hardtail, but then saw this bike. Do you think full susp is overkill for me at this time being a beginner?

[@bikesonline]

Hi Hollie, it really depends on your trails. If your main concern is comfort or your trails are a bit more technical and rocky, the D6 would be a great option. But if your trails are smoother and you want the easiest bike possible to climb, the Xtrada will be better

[@davidlindsley6892]

Full suspension you will enjoy it much more when you hit big bumps hardtail you'll feel every bump

[@cookiecanfly_]

Hey mate. I’ve got a polygon d5 that I bought second hand. I think it’s a large but the sticker isn’t on the bike how do I tell? Is the serial number plate thing a way of telling? Cheers

[@bikesonline]

Hey! The best way to do it would be to measure the seat tube and compare it to the geometry chart. To do this measure from the center of the bottom bracket to the top of the tube :)

[@cookiecanfly_]

@@bikesonline thanks man! I’ll give it a go. Will it matter if it’s already got a dropper seat post installed? Went for a short ride on it yesterday and have a sore lower back haha I’m 180cm talk and thought the large would be good. So I’ll do some investigating👍 cheers

[@bikesonline]

@@cookiecanfly_ Sorry I should have been a bit clearer! you only measure the part of the seat tube that is the frame so don't include the seatpost. Just from the BB to the top of the seat collar where you tighten the seatpost. The stock bars a pretty flat on the D5 so some higher rise bars may help your back too

[@cookiecanfly_]

@@bikesonline thanks heaps man that makes sense!🤙 hell yeah I was thinking the same! Might get onto that! I used to own a Merida one forty 400 but had to sell it. I liked its handlebars I might get some of those haha

[@enriquehernandez155]

$699.00 for the d5 is fine. But i was about to buy 1 and when I put my hight it $ 1000.00 that's what stopped me from buying it. At $699.00 i can buy it !

[@KpusFang]

My D5 front tire has air leak. I cant seem to remove the tire to check the inner tube. It's like the tire is glued to the rim. Any idea?

[@bikesonline]

Let all of the air out of the tube and leave the presta valve open so air can pass in and out freely. Stand the wheel up and use your 8 fingers to push the tire in towards the center of the rim. Once even a portion of the tire bead drops into that middle relief channel, the rest will become significantly easier. Hope this helps!

[@julianhunter9455]

If i got a D5 to start off with, is it possible to upgrade it components to the same as the D7 as time goes by and skill level improves?

[@bikesonline]

Absolutely! The main thing would be that you don't get the stiffer axle in the rear like the D6 and D7 but other than that it will ride pretty much the same :)

[@julianhunter9455]

@@bikesonline awesome! Good to know! Also, would it be possible to upgrade the D5 to have through axles eventually? Thanks for your time, love the channel by the way!

[@carlosbobbert862]

Thanks for the video I’ve been thinking hard about which to get as I’m kind of just starting but at the think of myself as a bit of an intimidate now, I just ride a bad hard tale but I’ve got the chance to ride very good full suspension bikes and felt how amazing they are and im wanting to upgrade the D5 I think for me isn’t the one to go for since I would just like it to come standard with a dropper post and I feel like the standard features of the D6 and D7 are better so I will go with either one of them but it just comes down to money for me. Spend a little more for more features or save a little? I’m 16 so what do you think is best

[@bikesonline]

All 3 bikes are good starting points, and the lower you start the more upgrading you may be doing in the future.

[@carlosbobbert862]

@@bikesonline that’s true thank you!

[@PaoloMTB]

Broke my rear hub and cant find the replacement but the boost one, can i use a rear boost hub on this? the site shows it uses the SHIMANO FH-MT400, but can i use the boost one? (SHIMANO FH-MT400-B BOOST)

The Siskiu D bikes are boost. Hopefully you got it sorted!

Does the d6 have rock shox? Also what is the order of suspension like fox then rock shox. That’s all I know

The D6 is not rockshox equipped. There is no suspension order necessarily. Fox and rockshox are simply competitors; No brand is better than the other.

We have something similar planned!

[@dragonflygenetics420]

Can the front fork be upgraded to like a 140 mm on this frame?

[@bikesonline]

We advise +10 if you choose to add travel up front on the Siskiu D. That would be 130. Going to 140 pushes it beyond its intended purpose, and we have the Siksiu T to handle that category.

[@cacasalterego2503]

whre that brand from?

[@bikesonline]

Polygon is from Indonesia :)

[@glynnb6572]

Quick question. I have two kids 9 and 11. Both are ready for dual suspension bikes. And rather than the kids d24 bikes which they may grow out of. I'm thinking of the d5s which are both 1100$ right now!!! What the genuine upgrade potential In that bike. I'm going to guess its a straight steerer for one. But would I be able to upgrade the rear shock at some point if I wanted? At that price I'm not sure I can miss out on them tbh esp as I want two. And as a newbie myself I'm seeing the d5s don't have through axles.. what does that mean? And can't It also be upgraded or changed? Would that affect upgrading the forks?

[@bikesonline]

Hi Glynn, they should both fit fine, especially if the 9 year old is on the taller side. The D5 is a great deal at the moment! The frame has a tapered steerer so upgrading the fork to a tapered one isn't a problem, all you need to do is change the lower headset cup/bearing. Upgrading the rear shock wont be a problem and a 1x drivetrain is a simple upgrade too. When it comes to the lack of through axles, the kids wont notice it too much unless they are on very rough trails, which really are beyond what the bike would be intended for. You can upgrade to a through axles fork, all you would need to do is change the front wheel. The rear however, can not be changed

[@fareastflexxx]

Hi! What do you think, can i replace a D5 link to D6\7 if i buy it separately? Thank you!

[@bikesonline]

Awesome to hear!! Yep the Pike was a game changer for sure :) Keen to try out a new shock soon too!

[@fareastflexxx]

@@bikesonline I think you have the wrong comment )

[@millsshumps1968]

No you can't swap out the link from D5 to D6/D7 because of their position on the frame, and makes no sense because the materials are the same. D6/D7 link won't make the D5 any stiffer by swapping out the linkage parts. it the suspension you need to change if you want noticeable performance difference....or the wheels from 27.5 to 29" as the D5 has frame clearance for the change.

[@nishasanthosh1530]

What's your opinion. Which is better....

[@bikesonline]

Check the end of the vid for all our thoughts :)

[@charleschenhua]

I looked thru my local bike shop and full suspension bikes starts at $3K, is this bike too good to be true?

[@bikesonline]

Definitely not :) The main reason why the Polygon is more affordable is that they are a factory brand (produce their own bikes) and we are direct to consumer. The components are the same as all the bike shop brands too (Rockshox, Shimano etc)
