One question is whether carbon fiber is the right material for let us say BMX frames. GT made a nice looking box beam frame called the UB2. The problem was that the factory riders would not ride it and went back to aluminum, at least for a time, because what they said UB2 was sluggish, especially out of the gate. Having recently learned about this complaint, ...

If chain us not slipping then id say you have a busted freehub by the sound of it. Take the cassette off, remove the freehub inspect the paws check for excess grease or lack of. Otherwise look at a new freehub body. I had the same issue you describe last week.

Honestly i have 2 of what you describe with a few variations - for gearing you don't need more than 2X11. Light i would consider looking at a dynamo hub like SON 28. Rear rack look at Thule, bike pannier rack (use to be called Freeload). Suspension and dropper post these days come almost standard on most bikes and you don't need to go spend $7k plus to ...

Grips are cheap - buy some new ones. If you really want to save these, turn them over so what was inboard is now on the outside. Or swap left for right. The clamp should be onto the solid metal of your bars, not floating loose in the air. In addition there should be bar plugs into the end - these are glorified rubber or plastic corks which help prevent ...

Short answer, no! Almost certainly the entire grip should be on the handlebar. Then the 2 pieces of steel pushed in by the screws will tighten against the handlebar giving much better security. The steel pieces should go in the cutouts on the hard plastic inner of the grip. I'm not sure how well the grips will work now that they are missing some of their ...

Next to the M and L, it lists 65"-70", and 68.5"-75". " is an abbreviation for inches. So at 5'8" (5 feet 8 inches), or 68 inches, the M is probably a better fit, but if the rider is still growing, you might get the large because it's so close. That said, it seems to be a very expensive bike to be buying without a test ride first, even more so when you are ...

The space is normal and overfilling should not alter this (over bleeding can be used to improve lever feel though see this blog article from Epic bleed solutions). As you say the pistons will adjust automatically. The gap left should be equivalent to the displacement of both pistons by the master cylinder (lever). That said if the calliper was not centred ...

ANSWER This is a bad idea. Your bike has 24 gears total, so its probably a 3x8. Thats three front chainrings and 8 cogs on the rear. You could get more road speed by having a smaller small on the back, or a larger large on the front. However the default rear cassette is 11-32 and 11 is as small as they go. Your specs don't say what the front chainrings ...

Given that all other things, e.g. type/diameter of the axle, are the same, the difference of two teeth on the middle chainring do not present a problem.

For help on jumping curbs, I would recommend a couple of youtube channels: Seth's bike hacks GMBN (Global Mountain Biking Network) They both have a lot of help on skills. In your case, I would look up "bunny hop" as that's what you are doing when hopping the curb. You probably won't hurt the rim as long as you have enough air in the tires. You can ...

The linked answer covers part the question or how to do it. To answer the question of damage and tire pressure - they are related. Best thing you can do is get a pressure gauge - either one mounted on a floor pump, purchase a dedicate one (digital are < $10 for a cheap one) or use a service station pump. At the maximum pressure printed on the tire, ...

You can use a pipe that you wrap around the QR to have a bigger lever, but be careful not to apply to much force (because you will have a lot more)! If the lever is stuck against the frame (so you cannot place your fingers around), try with a screwdriver first to pry it open(but put a cloth or something to prevent damage on the frame). Perhaps the axle of ...

I don't know about "oft-cited", because I haven't actually seen any cited. But distinguishing these standard electric assist bicycle from the "electric trail bikes" that have been round for a while, I can guess some of the advantages compared to an unpowered MTB: For the Rider/Purchaser (not necessarily the same person) ability to ride places they ...

I am talking about Electric assist MTB's (typically under 250W), not electric MX bikes. The ones in the middle (MTB's with 1000W motors) are really a new style MX/MTB hybrid bike that cause the most debate. Not everyone is healthy and fit enough to enjoy, or even attempt some of the best MTB rides. Electric MTB's enable a greater proportion of the ...

Given that the cassette is tied to the axle, if the alignment is changing, you have a few possible causes: Freewheel is worn out and has a significant wobble The pivot where the chainstay and frame connect is worn and loose Axle itself is loose, either through the hub, or at the dropouts When applying pressure to the pedal with the brake on, it will ...

I have a feeling that article is utter lunacy with a lot of big quotes mostly troll style to elicit a response. Mountain biking is a competitive sport similar to road racing. It's highly unlikely the rules governing it will allow for electric assists anytime soon. That being the case, the idea that sometime soon all mountain bikes will be sold with an ...

I think you are concerned with the 'rate of degradation'. I've designed sports helmets recently that use similar materials (EPS for example), but not for so long as to ascertain all aspects of durability. Your biggest concern would be loss in mechanical strength on photodegradation. The rate of change in the mechanical integrity of expanded polystyrene ...

First of all, mountain bike riding is a great thing for a couple to get into. A great entry level bike for around $350 is a Giant Revel. It is considered an entry level bike because it doesn't have disk brakes and only has front suspension, which is all you will need for your kind of riding. I started out with this bike and had no problems with beginner ...
