Black Ops BMX Bottom Bracket Set
- I bought these to replace the bearings in a Framed Impact BMX, as the bottom bracket in that bike arrived trashed.
- The “seals” are pieces of black plastic that seem like they will wear out very quickly, and when I tested these before I put them on, they spin much more freely without the plastic seals.
- Overall, for the price, these bearings are a great upgrade and/or replacement part for your bike.
- It worked perfectly, but the “sealed” mechanism is and it isn’t.
- It’s the same as a basic non sealed bb, but they added this plastic grommet the goes between the bearing ring and the rest of the assembly.
- It works to an extent, but note the after time and friction that grommet will wear out and start to protrude from the assembly.
- I’ve been using mine for six months and I have not had to replace it yet.
- The parts are made with really good quality metal, and I’m pretty sure it fits most if not all BMX bike frames.
- I been using this product for around 4 months and no problem so far.
KMC Z510HX DropBuster BMX Bicycle Chain (1-Speed, 1/2 x 1/8-Inch, 112L, Silver)
- High tensile strength = 1200kpf, mushroomed pins, flat inner plates with heavier and thicker side plates.
- Designed for high-torque BMX racing, not fancy shifting mechanisms.
- This chain was original equipment on my Specialized Tricross Singlecross and it’s a very sturdy chain and relatively corrosion-resistant, so when it was stretched out, I replaced it with the same model.
- It can be a challenge to get the special link off or on: it’s a more permanent design than you’ll find on dérailleur chains.
- It is also difficult to push out the pin to break the chain for fitting it to your bike.
- A hint if you are a trike owner whose trike has a derailleur or gear hub like mine: You actually will have to purchase two chains (and have a quality chain breaker tool to get them to required length).
- But it’s worth the expense IMHO; I will update the review when the trike has gotten some more mileage.
- I used my chain tool to remove excess links and it went on with ease.
- Best part is no more sound from chain, just smooth cycling.
- You better have a chain breaker though because there is no master link in this bad boy.
- That is a good thing but I think it should be noted as well.
- Spending more buys you little unless you race track (in a velodrome).
- I actually had to buy two chains to get the correct length.
- Never had any problems with the original chain (about 7000 miles), but since I replaced the back sprocket and wheel I decided to go for a new chain too.
- I dont have to retension my chain as much as with my previous kmc chain.
- It came in a small square yellow box and the chain was greasy.
