I just recently less than a month ago purchased a mongoose xr250 good bike for the money shifts & rides fine.?

But I was in Walmart %26amp; test rode the Mongoose Blackcomb %26amp; it rode %26amp; shifted like a Cadillac much nicer. Of course I'm not a bike racer or a bmx rider just a casual bike rider 90% on pavement %26amp; maybe on a lite trail. Thinking of trading in the 250 for the Blackcomb their isnt a thing wrong with the 250 %26amp; willing to pay100 bucks to boot. Is this worth the effort for no more than I ride %26amp; where I ride. To go to the expense of getting the best for a dept store bike someone help been battling this decision for a couple day's now %26amp; cant decide on the best thing to do .Is this a good idea.

I had the 250. For the money, it's a good bike. It's certainly not meant for any rough jumping, or serious mountain biking. The suspension isn't geared for that. It's a good cross-country style bike. If you're just a casual rider, then I'd say "no" to an upgrade. This bike is good for what you do.





As for buying ANYTHING in a Wally World, I'd say "no" again. The bikes are put together by some hack who probably has no clue as to what he/she is doing, as evidenced by the quality of work at just about ANY W/M you go to. You can do a basic check of gears, brakes, etc, and realize they did a crappy job. I had to completely re-tune mine up from the gears to the brakes when I bought it. Buy from a bike store. They specialize, and receive the required training. They can also make solid recommendations as to what's best for your riding habits.





Last word of caution: be careful about the mountain bike bug. I started with the Mongoose 250...and before long, I was up in the thousands+ for a better-quality bike. It's a catchy fever, believe me! Good luck.
Reply:Not a good idea. Within a couple months, the new bike will not shift as new either. The shift cables will stretch over time and need adjustment to keep the shifting up to par.





There is a device called a barrel adjuster at the point where the cable enters the shifter. Tighten your rear shifter by 1/4 of a turn (by turning counter clockwise) and see if this helps. Keep tightening it until you get smooth/reliable shifting.





To adjust your front shifter, put the rear on the largest cog and the front in the middle chainring. Turn the barrel adjuster on the left shifter until you have about 1mm of clearance between your chain and the inner guide on the front derailleur. I just tighten mine until the guide makes contact with the chain, then loosen it until the chain doesn't rub anymore.





I would be certain the shifters and derailleurs on the new bike and your bike are the same type. Buying the new bike will only satisfy your shifting problems temporarily.





If you enjoy riding, consider investing in a quality bike from your local bike shop rather than one from WalMart. The difference in shifters is akin to a cheap knock off golf club and a Taylor Made. You will get a lot more quality and durability from a bike shop, along with service (a word that doesn't exist in Walmart employee training).
