Polygon Siskiu D7 // Budget Full Suspension MTB - Crazy Value!! 

Finally a solid high quality Polygon Siskiu D7 review! Not just a specs list but a detail riding experience. 👍🏽 Enjoyed every minute of it!

Another great review. I have the Polygon Siskiu T7 (I already commented on that review video) and I have been considering selling it to get the D7 to get more of a XC bike. I'm still on the fence, but this review gave me some great insight on some key components. Thank you for the great content. Keep it up.

I have a D7 and have converted mine to tubeless. Just needed to tape the wheels, install a valve, and toss in some sealant. Enjoyed your review.

Great review, neighbor. I actually ride a Siskiu T8, often around the Fullerton loop. Small detail missed: the fork and front wheel are 15x100, not boost (15x110). Only the rear is boost 12x148. This is an upgrade, as the D series was 12x142, but you should notice that if you were to venture into better wheelsets, you should consider upgrading the fork too to a boost unit vs mix-matching boost rear with non-boost front.

Great review! Stoked to see an independent review on the bike, really well filmed too!

Awesome video, you have no idea how long I've been looking for a good review video for this bike!

IIRC, you said the frame and fork are boost. The frame is, but not the fork. I am a fairly new rider at 2 years and started at 45 years young. This bike has been great to me. I did swap the crankset to a 170 mm length from the original 175 after stripping a bolt. (Failed torque wrench, long story) Definitely less pedal and toe strikes now. As a heavier rider at 250 lbs geared up, I went cheap and upgraded to 203/180 rotors which has helped a ton! Also, mine came with some unbranded pedals that I changed out immediately. My 9 year old son loves them on his bike, so that’s good. Mine is a 29er Medium and weighs about 1 lb more than what you tested. A lighter wheel set is in my future. Oh yeah, the Nobby Nic’s that came with mine did setup tubeless while I was waiting for my new tires to arrive. Overall, as a fairly new rider, at 6 months of ownership and around 700 miles logged, I’m very happy with it. Especially for price vs spec. Thanks for the review. It was well done!

I own this bike (29") after downgrading from a Giant Reign Advanced Pro as I wasn't using it to its potential. The D7 is AMAZING value and the only issue I have with it is the low bottom bracket height which causes pedal strikes. But like he mentioned in the video, this is a good excuse to practice better pedal positioning.

Awesome review! Just rode mine for the first time today. Had a great time, though i think the rear suspension needs to be tuned a bit.

Like you read my mind. Got a Diverge after checking out your reviews here. Now am looking for something for those trails I should not have bombed on that one. It has its limits 😬. Will keep this one in mind. Great channel; great content. Keep it up!

These are $1200 now on black friday - what a deal !

The Bottom Bracket height issue is spot on, my Dad rides the exact same Polygon Siskiu D7 in size S. And he has to be careful when pedaling while turning, especially when he change the pedal to a slightly wider one. One correction though, the included Nobby Nic tires are tubeless ready, my Dad was able to convert his to tubeless by just getting a tubeless kit.

Great review. I just started riding on my old $250 Giant bike. It looks like this bike is perfect for me. Can't wait to try it out on Fullerton Loop, maybe I'll see you there.

i have an d7 and i run tubless with the stock tires and rims works great

We used to do the same stuff with 60-80mm of travel so I kinda think these modern bikes are OP and capable of anything.

Went from a vintage Small, 27.5 hardtail to a D7 29er and I love it. I ride mostly Bonelli in SoCal. Love it going up hill, but I do get nervous going down hill through some difficult rock gardens, but all in all, because of the downhill rockgardens, I am not overbiked for Bonelli. Though the bike does not call out for it, I look forward to doing some fun upgrades over time. My first upgrade was tubeless.

Thank you and great review! See that most of it was done at Fullerton Loop and a local myself and in the market for a full suspension bike. Getting back into it and still riding my hardtail Frankenbike from 15 years ago and enjoying it a lot. Your review just tipped the scale and leaning towards the D7...

I'm new to mountain biking, but looking at getting "the best bike I can afford" in about a year. I currently have a diamondback response xe hardtail 3x7 in medium (which is actually on the small end for me with a 32.5-33 inseam at 5'10 & 180lbs) that I bought used. I'll probably be on it a year till I can afford to spend the money on a T or D series. Currently longing for a T8, but wondering if a D7 might be better suited to a relatively old newbie like myself (I'm 40 and haven't been on a bike since I was 15 or 16) who is also out of shape (not fat per se, just muscles are flabby and completely out of tone, and my cardio health is "acceptable" according to my doc who wants me to improve it before age makes that harder). I'm so new that I don't know if I'll be doing those heavy duty drops and such as I improve. But, I want a bike that'll grow with me and is already set up such that it'll be wearing out the drivetrain and suspension by the time my skills are improved enough that the bike will be beginning to hold me back. So, that's why I'm looking now at things I'll want to buy in about a year. I know the N series is probably not right for me, as there's not really bike parks nearby and I have to fit cycling into my schedule of work and family (father to 3 young ones, oldest just started biking on her own on the sidewalk). There's several decent mtb trail systems nearby, but nothing bike-park-level. So, that's why I'm kinda torn between the D7, T7, and T8.

Can't agree more.... Superb! Value for money bike indeed...

Great review - thanks! Tossing up between this and the Marin Rift Zone 2

Hi there. I have asked this question on almost all of the Polygon videos I've seen 😂. A little bit about myself. I'm more than a roadie than a mountain biker. But I do mountain biking when the road season is over. I do have a Giant XTC3 (carbon)"26 which I upgraded for this. What I did this year was starting with mountain biking. I do XC. Question. Is this the bike I have to go for the fact that I do XC? I'm not a full time mountain biker but I want to enjoy it when I'm doing it. And I'm also looking for my first full suspension bike Thanks in advance ✌🏽

Glad to hear the small is only 32 lbs. 99 spokes had it listed at 36 lbs(probably for a medium 29er). I'm thinking about buying one for my wife's birthday. The geometry is perfect for the type of riding she enjoys.

Great video with good presentation. I have the T8 and really love it. Had to sub after watching this....some funny stuff in there for sure.....

This was a great video. I know this wasn’t your bike and I don’t know if you have ridden the siskiu t7 but do you have a preference and just looking at the specs, which one is better for the money?

I’m thinking this would be a perfect bike for me. Living in Houston has major setbacks for mtb riders. Most of our trails are small hills with lots of up and down climbing/descending. My local trails I ride only have 70 feet of elevation change total. The trails have to be laid out pretty creatively to make use of what downhill we can get. I would never use a long travel bike to its full potential, and I would wear myself out on the climbs. Down country and trail bikes are perfect for our geography.

Thanks for the cool review! And what if you put a fork of 150-160 mm on this bike. would it be appropriate for this bike geometry?

Bikes these days seem like an insanely good value. A couple of decades ago I paid close to the selling price of this model for a Turner Stinger frame only.

Looking for an good quality entry level bike for my friend, this one seems to check all the marks as far as price and quality of the components. Thank you for the review!

On the world famous Fullerton Loop! Great and helpful review.

Excellent review!

I have the older version of this. It appears to have been improved a bit more. Even a better bang for your buck now.

Yo that's the Fullerton loop u do that trail super fun

I chat with a salesperson yesterday in regards to this bike. He had the question in regards to the tubeless tires. He told me that it is tubeless ready. So now I'm a little confused cuz you saying that is not.

Just bought one waiting on delivery and losing my mind with anticipation! Killer review!

👀 Looks-wise, these look better than many of the top tier brands. The symmetry is just right whereas the name brands always appear to have something goofy or off with the shape.

But on its my polygon trid zz, I put rockshox sektor 150 mm. And everything is fine. But I want to try this frame and also put a 150 mm fork.

What are your measurements? How tall/in seam.... Just wondering how well the size small fit you and want to compare. I am 5'8ish" with 31" inseam and polygon recommends M 29er but I know sometimes those recommendations are not ideal and can be oversized. Thanks.

great review. Just a question about the size. I am 180 cm and just have the choice between M 43,5 cm (27,5'') and L 48,7 cm (29''). What would be your recommendation?

is the 2023 frame for D7 same frame as T7/T8? It looks like Polygon´s only manufacturing is the frame and verything else was mass purchase thereby lower price for whole bike to end consumers. So the wheels for the 2023 frame and nobby nic tires can easily be converted to tubeless? I don´t see any tubeless ready logos on either the tires or the wheels.

Im getting my XL D7 tomorrow , What would you upgrade ? ( this will be my first full sus )

I've been looking to upgrade from a hardtail to full suspension and have been looking at the Polygon bikes. My only issue with going to full suspension is my height and weight. I'm a big at 6ft 4in and weighing between 250-260lbs, my concern is bottoming out with that rear shock

Could you put bigger tires on the d7? What is the max tire clearance? 2.6s would stand a good bit taller than the stock 2.25s and raise bb a bit. Or maybe change the fork air shaft to a 130mm

polygon also got gravel bike, which use grx 8 series groupset plus dropper post.

We small mom and pop LBS'ers would be glad to assemble and tune it too for all you non-techies. I'm speaking for the non-snob cyclists working on cycles and sharing their wealth of knowledge...not the snobby jokers that drove the bus down this dead-end DTC road. We authentic shops are definitely having to constantly change our business model...that's for sure. Heck we'll even "show and tell" when you come in "shopping around"...only for you to get on your phone and order one of these DTC's when you've learned all about the latest and greatest technologies and components (subtle hints of sarcasm placed here). ;)

Does the makeshift stick/bike stand come included with the bike?...

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)

I have the 2021 D7, Cracked at the seat tube top tube . 3 months for a replacement. Beware.

@The Bike Sauce.. this video is 2 yrs old so you probably won't see my comment. If you do I was wondering how tall your friend is that he got a size S frame? I hear these bikes run larger than most and if on the border of the size chart to size down

I love mine but I have one huge complaint- pedal strikes like crazy. 40 miles on mine and I've had more pedal strikes than 2 years of riding on my old 26" FS 2001 Santa Cruz both have 175 cranks

Marin rift zone 1 or d7 which should i buy confused

I have this bike and I converted the tires to tubeless with sealant, tape, and valve stem... seems to work fine and the walls of the tires seem thick enough and "tubeless ready" compared to other bikes I've got. Could you double-check on this? I also checked and according to google, all of Schwalbe MTB Tires 2015 onwards are tubeless ready...

the front is NOT boost, only the rear wheel

What did your friend upgrade to produce 32.9lbs? Based on Bikesonline, stock weight 34.lbs.

Wondering how you got the dropper post all the way down into the seat tube . I couldnt get the post that low even when pulling the housing while lowering it .

i agree with you

I am on the market for an MTB, and I am trying to decide which one to go with, Siskiu D7 or T7? as of today, they are $300 apart because of the D7 $100 sale discount. The D7 is different from T7, but which one is a more all-round bike? I consider myself a beginner in MTB riding. But I would instead buy a buy that can grow with me.

that fully loop ride

After about 3 years the last Keurig stopped working ru-vid.comUgkxBrV-RbF5Nk0Rlt9i15aao-YMzqzTG8Vf initially was able to unblock, however eventually we couldn't fix. That one was a replacement unit sent by the manufacturer after we had problems with our very first Keurig. This works fine (lol, at least for now) however I didn't realize the water reservoir was so much smaller than our prior unit. With 2 people having one or two cups of coffee each morning, it seems like I'm refilling it daily. Otherwise just happy to have the convenience of pod coffee vs. making a morning pot.

I have a question to change the sespension what tool will I need

one of the best budget Full SUS, no need to upgrade

Good review

I have been looking for a new bike for weeks and i think i found one!

Love this ❤🎉😊

I HAVE ONE AND NEED TO REPLACE THE HUB REALLY WANT TO GET SOME HYDRAS BUT DONT KNOW WHERE TO START...WOULD APPRECIATE THE HELP..!!

I have offer for this bike: 766 euro. It is well price IMHO :) I think, I'll buy it.

I'm taking from this that it needs better brakes and overforking.

Can you upgrade the suspensions to 140mm travel-150mm??

This one or Marin Rift zone 2 ?

I really liked my D7 until the frame broke at the seat post and they told me there's "at least a 3 month wait for the warranty replacement, but probably longer". A warranty is only as good as thier commitment to honor it.

Think I could race this bike?

Ordered a polygon... Never got it... Had to challenge the charges with PayPal just to get someone at bikesonline to speak to me... Imagine if you had a problem with the bike?... never again.

bottom bracket height and the fact i have to find service instead of getting a bike from a local shop...Pass...maybe as a second bike when i have money to change a lot...

What is the cost sir..

Rockshox is a SRAM company😁

Bangga jadi orang indonesiaaa

the craziest part, D is for Trail T is for Downhill Crazy Indonesians

Aun para algunos ese precio es elevado ajajaja.

This bike is now 1200

I have same bike
