The Fantom 29 thread
So I got this new Motobecane Fantom 29 hardtail mtb and I was finally able to get it out on the road yesterday and today. Hopefully our weather will be settling down and I can get it out to the park and the singletrack trails soon.

Yesterday I didn't have my Enduro 8 cyclocomputer configured, so I went to mapmyride.com and saw that I rode about 6.5 miles. It was around 8:45 a.m. and it was dreary and drizzly. When I got home my left hand was a little numb and tingly, but otherwise I felt great.
This afternoon I went out for a ride and did about 2 miles more, the weather was mostly sunny and hot. When I got home, my hand wasn't tingling. I don't know if the cyclocomputer is configured correctly, it says I road 6.5 miles today, but I know I rode over 8.5. It said my top speed was 19.1 mph, but I don't know if i can trust that. I need to figure out why my front disc brake keeps singing to me. They are my first disc brakes on a bike, they are Avid BB5 BallBearing Mechanical Disc with 185mm rotors.

I found a blog that I spent about 2 hours reading one morning and it said that the bike ran a bit big, the company recommended a 17" and that probably would have been okay, but I like the 15.

Here's a photo of my friend Larry assembling it for me (we were at a boy scout meeting). I was supposed to "help" him, but then the Scoutmaster asked me to talk with some new parents who wanted to sign their boy into the troop and had a younger one for the pack. I resigned as Scoutmaster after 6 years about 6 months ago so I could be Cubmaster again. But i digress, here's another photo of the Fantom 29

Did he say how difficult it was to put together? I am not overly concerned about assembly. I think I can manage and I have a couple buds that can assist if needed, I have just not done it before. From what I have read it should not take too long. Looks like you put some bar ends and a light on it also.

I ordered the bar ends from Nashbar (Nashbar Bar Ends) for $9.99
The light is from Harbor Freight, I think it is Bike Pro brand. It cost $6.99. Very bright, I wouldn't ride on a street with no street lights and count on it for illumination, but oncoming vehicles can definitely see you.
I also got a Topeak bag for under the saddle, and put a red blinky on that.

Glad you like your new bike, but I think this illustrates the pitfalls of buying a bike on line. If you bought it local you could have tried it on for size, that frame looks awfully small, too small IMHO(we are about the same size). There is a lot of seat post showing, is it an extra long, and is it inserted far into the seat tube enough? Having that break during a ride would be painful. My wife ride a 15 inch frame, it is too small for me to be comfortable on it.
Also, you could pester the LBS about the front brake until it was correct.
Since I was considering getting a bike from BikesDirect, I now have more food for thought.
Thanks for the report, and I hope you get the issues straightened out so you can enjoy the new ride.

The seat tube is fitted fine and has plenty of room. My friend Larry who assembled it, used to work at a Trek dealer bike shop owned by his dad. He is an excellent bike mechanic. He examined my fit and tweaked the handlebars and seat, and said it's a good fit. I don't have to bother an LBS for the brake issue, first I will try adjusting the brake myself (I do have some mechanical know-how of my own), if I still have some squeak, I'll bother Larry.
If I did need to pester an LBS for the squeak, I'm sure they'd be willing to take my $ to fix it. Meanwhile, Larry was over to the house the other night so I could pay him back, a 12 pack of Magic Hat halloween pack, and a bottle of Ommegang's Three Philosopher's Ale, we enjoyed some cigars and a few beers on the back porch. I probably won't be doing that with anyone from the LBS.

I just assembled a couple of bikes with disk brakes for the first time and it took a number of tries to get it right -- and a number of adjustments until the cables had stretched fully. Now they work just fine. I read a post from a guy who used a piece of plastic he described as "the thickness of a gift card" between the movable pad and the disk to quickly adjust the brakes. When I get a spare evening this week I am going to see what kind of "shim stock" I have laying around and give that a try. Frankly I would have designed them so that you just bolted them to the fork and used a couple of screws to adjust them side-to-side but these were the entry level disk brakes. Maybe the nicer ones have more precise adjustments.
The bikes I assembled were from Nashbar and while I was happy with the quality for the price, the documentation was poor. I've built a number of bikes up from bare frames so it wasn't too bad, but if I hadn't had that experience, I might have found the job to be too difficult. The disk brake manual was separate and much better, but it would still have been very difficult if I wasn't handy with tools.

However, with all my prior knowledge, if I didn't have a friend like Larry, I'm not sure if I would have pulled the trigger on an online bike purchase. He has also built his own mtb from the bare frame.

Somehow I knew this was going to become a debate on BD. I have been buying everything online forever and have had very few problems. I do support my local bike shop by bringing him anything I need service on or purchasing things that have a competitive price. If he sells a product that costs twice as much as another, be it sold online or the shop next door I am going to buy the product based on a number of factors, price, customer service and so on. I am not buying at BD to shun my LBS, I am being a smart consumer. If either of the LBS in my town refuse to service my bike because I purchased online then I would never have purchased a bike from that type of individual anyway. If I buy a bike in Boston and move to Alabama is the LBS going to turn me away? I think not. We all do as much research as we can on fit, components, trails, accessories to have a pretty damn good idea what we are getting into. If I hate the bike I get from BD, I get another. In fact when I get my bike tomorrow from BD I may bring the entire box to the LBS and pay the $100 to have then assemble and tune it. And I bet he will rib me about the purchase and tell me I can pick the bike up in a day or so.

Assembly on bikes is not difficult- mainly final tightening of bolts- fitting the wheels and adjusting the brakes so should be easy for anyone with bike experience. Set up on computers can be though as you have a few parameters to dial in- Wheel size and possibly a few other items- but all you have to do is read the Instructions. As we are the males of the species- we don't even need them till all else fails

Disc brakes though and they can be a fiddle. Setting the pad distance and whether the rotor is true can take a bit of settling in. Unless you spend as much on the brakes as you did on the bike but that is probably going over the top.

To derail my own thread slightly, I am pleased with my online purchase experience and will most likely do it again in the next six months.
If this one becomes available in my size, I'd be hard-pressed top ignore it:

This is another one I have my eye on:

On the computer, do a roll out and program it for the actual tire circumference on your bike. On the brakes, try cleaning the rotor with rubbing alcohol and a cottom ball. I have BB5's on my Coda and have to do that now and then.

Gary, no one seems to have addressed you cyclocomputer issue. There are a few things to look for.
1. make sure the set up is correct for your wheel size. The best way is to set the bike in a smooth flat floor (garage is perfect) with the stem at the bottom (6 o'clock) and mark the floor at that point. Roll the bike forward one rev. Mark the floor again. Measure the distance in mm. That is the # you put in the computer at set up.
2. Make sure it is set up for MPH not KPH. Sounds like it is, but it doens't hurt to check.
3. Make sure the spoke magnet is positioned correctly and is tight. The same goes for the sensor. Get is as close as possible with out touching.
Perhaps others have other ideas.
Look forward to seeing you out there climbing the "hill" on Trail's End!

Just a warning----Road bikes and you can go TOO small so make certain that the bike is the correct size before buying. MTB sizing will not have bearing on road size-As I found out on my first road bike. You do need a longer top tube.

1. Cool bike.
2. The fit looks fine to me. If it feels good, ride it.
3. Disc brakes are notoriously finicky. Just wait until you have your first biff and you bend the rotor a bit. Make sure Larry is nearby.
4. Are all rotors on 29ers 185mm these days? I thought they used the larger circumference rotors only for downhill bikes, but I know little about 29ers.
5. Have you ridden the "standard" MTB before? I'd be interested to hear about which one you like better.

On a Specialized Roubaix I was a 50 cm. I could swing a 52, but the 50 felt better.

2. Absolutely
3. hehe
4. I don't know, some might be 160mm
5. Not really. I love the way this bike feels. We'll see how it dos when I get it out on the singletrack.

Here is an update on my 29er Gary. I wanted to send along a pic also. The other two bikes are being neglected for a while. I will eventually clean up the Bottecchia and try it out but for now I am really enjoying the Moto. For the record I put the thing together in a few hours time. I took it at a slow pace and watch a buttload of you tube vids to tune it. Everything runs great.
I hope you are riding the heck out of yours.
