Seven Cycles Duo 2003 Full Suspension

DESCRIPTION

Featuring Maverick’s groundbreaking Mono-Link™ suspension technology, the butted titanium Duo is ultra durable, yet light weight. The design pulls the rear wheel forward and down as it returns to a top-out position. This increases traction while preventing bobbing by counteracting the rearward weight shift a rider experiences while accelerating. Mountain Bike calls it, "The best titanium suspension bike we’ve ever ridden."

I got mine a year ago. Titanium is a great ride. This is a beautiful handmade bike that cost 10k new and is made by one of the best boutique builders. Has a great ride and you can’t destroy it like a carbon bike. It tracks nicely and it’s a pleasure with its full suspension. The tech is a little old but I like it. It was tops 15 year ago and now it’s a bargain

Weakness:

26 wheels are out of fashion so you can’t get as big a tire selection. But thar keeps the price down. If these were 29ers they would cost 5k used. I don’t mind the 26 inch wheels. It’s not as light as carbon. The weird dual attachment point creeks a little on climbs but the power transfer is excellent. It’s an unusual choice but I think at the current price of 1500-2k it’s a deal. I got mine for 1200 and put 600 or 700 into making it perfect.

Climb, Descend, and everywhere else in between. It's Seven! The built is awesome.

Weakness:

I wish Seven would offer the seat tube bigger than 27.2 so I can put Maverick, Crank Bro seatpost on.

Seven does not offer them any more but the good news is Eriksen does.
The original mono-link is not good the noodle is not securing the cable keep popping out at the most crucial time.

So I recently replace it with new Modified Mono-link with ISCG tab to be compatible with Hammerschmidt. A small problem there where I could not get the 2 bolts out. They are different than the Maverick or Palomino. I went to several shops including 2 Helen's but They could not take them out I ended up order 2 new ones from Mavericks and Reamed them out.

Can be a bit noisy creaking by BB.

But all of these are quite minor for a great bike. These problems occur over 6 years or so.

Seven Custom program is awesome. Not the cheapest nor the fastest built, but definitely worth the wait. My Duo does exactly what asked for.

I love this bike. I love Mono-link period. They are by far the best climber out there. Hardtail like with no bob, but suspension stay active thru out excel especially technical climb.

Rolling singletrack is awesome on this bike. It just want to accelerate and carve turn. The big plus of monolink design is that it tends to stay on the background means you don't have to think about what it's doing. It just does the job.

When Maverick offer the Mod link so that the bike can be fitted with Hammerschmidt I jump at the chance. Now the G-out section and surprise climb is a welcome challenge. Will post a follow up review how HS pair with Duo.

I've run my set up with all wheel format available for Mtb
I tried 96, 76 with 650b in the front, I even tried 700c with 35c road tire. With Maverick fork it's just the matter of putting spacer to limit the travel. And they are all great set up. They works. giving a new bike feel. and when I go back to 26 set up then the bike feels like an old best friend.

I love Monolink design. I started with the ML7, then I bought a more XC Palomino then the ML8. I was convinced that this is the design I want to spend extra cash on building a custom frame. So if you are wondering if this bike is for you, look for a used Maverick frame or palomino online. Build it up with spare parts. You won't be disappointing. It's fall between XC and AM bike.

This is a followup of my followup. i.e. My third review.
Strengths remain the same: Almost zero bob, still feels tight after over 5,000 miles of riding.

Weakness:

This bike had been a disappointment durability-wise.
After breaking the suspension bolt (7 mile walk home), I managed to break a weld down where one of the rear dropouts connects to the frame. Five-mile walk home....

Seven was good about the warranty on that one. Sent me a UPS sticker, I sent the rear triangle in, and they fixed it.

But now I've recently stripped all the threads out of the drive side of the BB. Didn't toast the frame because the monolink is where the BB lives and it's replacable. Although I'm 220#, I'm not a strong, fast, or hard rider.

But remember how I was ranting about the cheesy feel of the suspension bolts? Well, turns out that the monolinks/BB thing is made out of magnesium. Was it the material? I dunno.... but the thing sure was stripped. One day it was OK, the next day it started creaking on the way out and when I got it home the BB spindle assembly was rotating freely. Man, those threads were *gone*.

This time no warranty from Seven. But I called Maverick and the sales guy said something about a "bad batch of monolinks before I started working here..." and sent me another one. But, get this, the replacement's threads are partially wacked right out of the box.

I've learned that Maverick has redesigned thier monolink tb made out of aluminium/i-beam instead of magnesium/box and I think I'll just pony up the $200 for one of the new ones just to get back on the bike (it's been 3 weeks...)

Seems to me like one failure: "Oh well, stuff happens".

Two failures: "Geeze, aren't I the unlucky one."

But *three" (count 'em: 1-2-3) major failures?

But I still like the bike although my enthusiasm for SevenCycles has waned a little after they failed to pick up the warranty ball and run with it.

Dunno if it's because it's the only bike I've ever had that fit me (I'm tall, funny proportions) or it's something else.... but it *is* a joy to ride.... until it breaks.

Bottom line: knock off another chili for durability.

Strength:

Craftsmanship that is truly something to see. Custom fit, exactly how I wanted it. Not super plush but after coming off a Ti hardtail, its a good thing. I could not be happier. It climbs like a hardtail, and handles like a dream. NO BOB!!

Weakness:

as mentioned earlier, front derailluer is a bit tricky to set up. Although it works well, it's a tight fit by the shock.

It's the perfect bike. It was a tough decision to buy a f/s mtb, but I feel I made the right choice. The quality is superb, the service from 7 was outstanding, and it was built to fit me perfectly. Buy it for the ride, fit, and quality. The oohs and aahs are just the icing on the cake. As far as the price goes; you get what you pay for.

First off I borrowed this 2002 bike off my doctor friend.The bike was decked!Strengths; good plush efficient peddler,good traction,doesn;t show scratches,looks like a pc. of jewllery!

Weakness:

When landing from a jump the bike feels much stiffer,due to the fact the wt. of your body is on the cranks when you stand.The magazines are quite accurate when saying it is an awesome epic ride,I did a 4hr. 70km. ride on this thing and liked it very much.My razorback or fuel may be better race bikes but don't get me wrong this is a very deceptively fast bike! PRICE!!!!!!!

The Klien would be cheeper.I wouldn't be afraid to buy this technology but I prefer a more active FS bike that feels snappier.

Strength:

The bike is a great climber on steep and rocky, rooty, technical trails. It soaks up bumps well. The suspension is efficient. It sprints well out of the saddle. The manufacturing and welding is outstanding.

Weakness:

The bike was heavy for a bike that I spent this cash on and had it decked out with light components. It felt slow and was slow climbing long steady inclines. The bottom bracket height was low at 11.75", and continually caught on things until I adjusted my riding to accommodate for this. The pivots creaked terribly and had I had to send the bike back to the shop numerous times as well as being sent back to Seven which left me without a bike on regular occasions (once for a month). It is tough to race when you don't have your bike. No one seems to know what the shock pressure should be at. I was told 20 psi when I orded the bike, 40 psi when I received the bike and 65 psi when I noticed that the bottom bracket height was lower that was specified on my initial order. Increasing the air pressure effectively raises the bottom bracket height, but also effects the suspension.

The bike is a very good trail bike when it is working. The suspension works well and is efficient. The bike climbs well in technical accents. However, there are a few definite draw backs with the bike and the way I had it set up. The bike seemed slow and was slow on long steady accents. It was definitely a sacrifice in race situations. Continually having to bring a bike in for service of its pivots is frustrating, however they are not creaking at this precise time. The lack of knowledge of the manufacturer on proper shock pressures is hard to understand. The Sid is a poor choice for a bike with disc brakes. I am 160 lbs and noticed significant amounts of flex with braking that was not evident with rim breaks. The tubeless tire system is heavy and puts weight exactly where you do not want it, the farthest from the hub. I am making a few changes to the bike that will hopefully improve some of the weaknesses. I will comment on thse at a future date

Plush ride, the greatest climber I have ever used.
The long wheelbase & the slack seat angle worked great for me.

Weakness:

Front derailleur sucks ...
Not so plush on the descent.
very very expensive $$$$$$$$$

I fall in love with this bike, it's the best climber I have
ever experienced plus it is such a beauty that I have put
them near my bed (which my wife didn't like very much ...)
and have very hard time returning them off to the bike shop.

It might be expensive but what the hall are we living for !
The blur is much more plush than the Duo but the Duo climbs
better and ride like a dream.

Almost zero bob, still feels tight after 4,000 miles of riding

Weakness:

The bolts used to mount the "monolink" are just plain cheesy. Some engineer's wet dream if you ask me.

If you remove/replace them to service the monolink on any kind of regular basis as recommended by Maverick, they are going to be damaged for sure. I've reverted to just applying a drop of Pro-Link into each side of each bolt when they start to squeek.

Removing them is no problem. Getting them back in is a bear. Aligning the monolink perfectly with the frame members it interfaces with is next to impossible "freehand" because the bolts are not shoulder bolts - i.e. the threads stick out to the exact diameter of the rest of the bolt so you can't tap the bolt in to force the final bit of alignment without damaging the threads.

Some sort of mandrel would help a lot - something that can be tapped into the bolt's path to line everything up before slipping in the bolt.

But the real solution is to make these things shoulder bolts and make them out of something a *lot* less cheesey - so they can be tapped into place.

Putting a nut on each end instead of just one end would be a plus too because it would make them replacable in the field. As it is, you have to remove the drive-side crank to remove the bolts.

I've already broken one (seven mile walk to get home...). Seven said "bad bolt". I think it was me trying to learn to to tail whips.

The bolt thing probably looms larger to me not only because I've broken one, but also because makeing the bolts readily and reliably removable/replacable would make this a great travel bike - the parts left when the mono link is removed are smaller than anything you'll get from an S&S coupled frame.

This is a followup review to the one I wrote a little over a year ago when the bike was new.

Still love the thing. If it went "poof" today, I'd call up Seven and ask for exactly, precisely the same thing tomorrow.

Got a nice hardtail and I enjoy riding it from time-to-time...and currently use same as my commuter bike.... but I keep coming back to the Duo for the most pleasant ride, and will probably just put the commuter wheels on it during the week and more-or-less retire the other frame.

There is so little bob on this thing that I can feel my squared-off (i.e. poor) pedaling style almost as much as on a hardtail. Couldn't feel it even a little bit on any of the other FS bikes I've ridden.

Yet the SUS does it's job: firm, comfortable, but not punishing, stays hooked up on stutter bumps, no perceptable bot.... What more could I ask for?

I knocked off one flamin' chili because of the monolink bolt thing.

Called a few people at Seven and Maverick - but got the feeling that that they were being polite while listening to some lunatic rave.

I still think it's a 100% valid point - and apparently sooooo simple to remedy. Frustrating.

-Out pedals everything under the sun, absolutely NO bob what so ever
-Fits me perfectly, THANK YOU SEVEN
-Little maintenance
-Extremely agile
-I couldn't break it even if I tried
-Carves up singletrack like nobodies business

Weakness:

-Most people who ride this design say the front derailleur but I got mine working flawlessly. You just need to have the right equipment and the right mechanic.

This is the best bike that I have ever ridden. Every ride I have been on has felt like a magic carpet ride because the bike fits be so well.
I have a nasty tendency of breaking frames and this bike has lasted 14 months with no issues. I won't be surprised if it lasts another 14 years because of the craftsmanship and precision that it was built with. With the front derailleur; the best set up that I have found, for any mono-link design, is to buy the braze-on mount from Maverick American and put a Dura-ace Triple front derailleur on. Then put on an Avid Rollamajig and a Shimano flat-bar road shifter.
The suspension does take a little time adjusting but once it is done the bike handles like none other, and the rebound knob does do something unlike many people claim in the palomino reviews.
This bike handles and rides like you want it to. If you tell seven to make the steering VERY quick they will design the bike in such a way that if you even think left, the bike will turn left. I had mine built up very beefy yet agile so I would break it. The whole bike weighs in at 27 3/4 lbs. and I love it. I have never worried about breaking anything on it because it is so strong and reliable. Even at that weight it still can out accelerate and out maneuver most every other bike I see (and I do see a lot considering I work at a local bike shop). The best way to describe the ride is that it is a hardtail with four inches of travel that isn't afraid of anything. It ascends and descends with the greatest of ease and it carves through singletrack like a laser guided missile. It has been the best investment of my life!
