Blue Mongoose Beast/Digital Camo Beast-Specs & Observations

Postby desertguns » Wed Jul 10, 2013 5:05 pm

I'll amend this post as I gain more data.
ASSEMBLY - As is often mentioned on this forum, check everything before riding, whether it was assembled at the store or not. I picked up mine from the store, still in the damaged box. It had scratches on the frame & cranks. Didn't really care as I had other plans anyway. You only have to assemble the bars, seat & front wheel to fork. Tires are already inflated as well.
PROBLEMS 1. The headset was very tight. On closer inspection I found that the lower bearing was misaligned, and the bearing keeper was pinched between crown race & cup. 2. The top bearing was greased, the lower was not. 3. The front wheel bearing was too loose and was only greased on one side. Rear bearing was greased & properly adjusted, and surprisingly, so was the bottom bracket. Had that sticky-as-hell Chinese grease on the chain. Will all get torn down after first wet ride & get lithium marine grade grease. AND, double check all bolts after riding a bit, especially the quill bolt & stem bolts . No stock lock washers & mine had loosened up to the point I crashed. My bad... Almost forgot - 4. the bead was not properly seated on the front (tire pre- inflated). About 6" radius where the bead was exposed. Thought there was a bulge in the tire at first when I started riding. 5. Removed tire & found rim strip only covering about half the spoke nipples. The rest had been pressing into the tube.

The first pics are the Beast bone stock. It came with white rims - I painted them black. May end up desert tan camo on the frame.

Alloy parts - rims and stem only. Everything else is steel. Spoke nipples are steel. Rim liner is rubber strip.

Drivetrain - 36T x 18T 170mm square taper crank arms. Large nylon platform pedals with studs, similar to lower-end Welgo. KMC chain was stock on mine but didn't have a master link.

Seat/post - The post is not 27.2 like the other big box geese. It's 28.6mm x 350mm - It also lacks a standard seat post retaining collar. Instead, the seat tube is split with a lug welded on, and the quick release pinch bolt runs through the lug. Stock seat w/ post is 1 lb 11 oz. Seatpost w/ hardware 11oz/312 gr.

Handlebar - Alloy stem - 50mm. Steel bars weight 1 lb 7 oz/652 gr.(with grips) 660mm width, aprox 70mm rise & 6' sweep. 22.2mm clamp size - so you're pretty much in the realm of steel BMX bars (or street cruisers) unless you go with threaded to threadless adapter to get to 25.4 or 31.6. If you do go this route, I'd definitely recommend 31.6 clamp size. I'd be concerned about bending a 25.4 alloy bar with this bike. Quill is 1 1/8" threaded.

Weight - 46 LBS Here's how it breaks down:EDIT Got a new digital scale today. It's actually 48.2 LBS. Will re-weigh components at next tear-down.
front wheel assembly - 10 LBS
Rear wheel assembly - 12 LBS
Frame,fork,bars,seat,etc - 24 LBS

Now, here's where a bunch of weight can be trimmed if you have the bucks - tires. 6lbs 4 oz to 7 LBS a piece And the stock tubes are pushing 2 lbs a piece each as well. You can buy Surly ultra-light casing tires and their tubes & cut about 5-6 lbs off the bike...or for $100 less, buy a second mongoose Beast! I'm looking at Vee tires as a compromise, but not anytime soon.

Mods -
Kalloy SP-267 UNO Seatpost - 28.6mm x 350mm black - $21.00 7/2013
PROMAX BMX HANDLEBAR -700mm WIDTH -22.2mm CLAMP DIAMETER -200mm RISE -HI-TEN STEEL-BLACK - $20.00 (test) 7/2014
Sun 32T crank w/ 154mm alum arms - made in Taiwan $20.00 on ebay. 1/2014

With the white rims, reminds me of the BIGFOOT monster truck with 10 foot tires!

^^^...and the bike is sitting on front of a '96 Ford F250 wearing Bigfoot tires from Big-O! And the circle of life is complete...

One side of the bike is done in digital camo tape. Not quite what I wanted but gave me an idea what desert camo vinyl wrap might look like. Might confuse onlookers this way too - guy rides in on a blue bike & leaves on a camo bike?... :P

If you have the right backdrop, they may not see the bike just you and the wheels...if may freak them out :grin:

dg--

A great thread, thanks.. 8-) ..

FYI--here is a link to the new Vee brand V-8 beastly tires:

http://www.universalcycles.com/shopping ... egory=4743

At $61 per each, they are fairly economical. Universal offers a 30-second price match, too.

Keep on weighing those parts!!

Are those steel crank arms the same as the ones on the Onyx
29er??

If they are, then they weigh about 1.5 pounds each!!

3 pounds of crank arms.. :shock: ...

I use Universal quite a bit. I'm looking at a different Vee tire - same price, more aggressive tread- 120tpi, kevlar bead, 1430 grams

The cranks are steel & I'm sure they're heavy. Probably not the same crank as Onyx (Kent) and this is Pacific. Although there may one plant in China that spits out all the arms 8-)
