Montage

  1. Verwijder het wiel en open de remklauw.
  2. Trek de borgpen of splitpen eruit en verwijder de oude remblokken en veer.
  3. Reinig de binnenkant van de remklauw met remmenreiniger voordat je de nieuwe blokken plaatst.
  4. Schuif de nieuwe DBP-21 remblokken met de meegeleverde veer in de remklauw. Let op: raak het remoppervlak (de compound) absoluut niet aan met vette vingers – vet of olie maakt de blokken direct onbruikbaar.
  5. Breng de borgpen terug en zorg dat deze correct vergrendeld is.
  6. Monteer het wiel terug en rijd de blokken in: rem 20 tot 30 keer krachtig van 25 km/u naar stapvoets (zonder volledig stil te staan). Dit activeert de compound, voorkomt piepen en geeft maximale remkracht.

Veelgestelde vragen

Voor welke Shimano remmen zijn de DBP-21 remblokken geschikt?

De SUMART DBP-21 is specifiek ontwikkeld voor de Shimano XT 2003, ook bekend als BR-M755 en BR-M756. Controleer altijd het typeplaatje op je remklauw voordat je bestelt.

Wat is het verschil tussen semi-metalen en organische remblokken?

Semi-metalen remblokken bieden meer remkracht en zijn slijtvaster dan organische blokken, maar kunnen iets meer geluid produceren bij koud weer. Ze zijn ideaal voor technisch terrein en langere afdalingen.

Waarom is het inrijden zo belangrijk bij semi-metalen blokken?

Semi-metalen blokken moeten correct worden ingereden om de compound te activeren. Rem 20 tot 30 keer krachtig van 25 km/u naar stapvoets – zonder volledig stil te staan. Doe je dit niet, dan kunnen de blokken tot 50% minder remkracht leveren en gaan ze piepen.

Wat gebeurt er als er vet of olie op de compound komt?

Vet, olie of kettingolie op de compound maakt de remblokken direct onbruikbaar. De blokken glijden dan over de schijf in plaats van te remmen. Raak de compound nooit aan met vette vingers en gebruik bij montage altijd schone handen of handschoenen.

Zit de veer standaard bij de set?

Ja, de SUMART DBP-21 wordt geleverd inclusief veer. Je hebt geen extra onderdelen nodig voor de montage.

Hoe weet ik wanneer mijn remblokken aan vervanging toe zijn?

Vervang de remblokken als de compound minder dan 1mm dik is, als je een verminderde remkracht ervaart, of als je een schurend geluid hoort bij het remmen.

No customer service for product under warranty
Color: Beige
loved this umbrella for the 4 months we used it. did a lot of research to find an umbrella that would stand up to New England "breezes" -- this one was advertised as wind resistant; bought in June 2025, seemed very sturdy, really nice-looking, used on our patio (installed in the base the recommended base) through the summer; stored indoors for the winter; brought back onto patio a couple weeks ago. On a day with average wind a couple weeks ago, the tilt mechanism broke. Umbrella did not fall over, a gust of wind just forced the tilt mechanism to snap. Spent a lot of time trying to fix it, but it's permanently broken. It's less than a year old so still under warranty, as stated in the materials they sent with the umbrella. Same materials list the email to contact if there are any problems with the product. Have emailed the company, twice now, asking for a refund or replacement. Radio silence. Don't buy this unless you're ok with throwing it away after four or five months of use and being ignored by customer service.

Third time in 10 years nerding out on an Amazon patio umbrella on a budget...
Color: Navy Blue, Color: Navy Blue
Color: Beautiful, but the fabric is thinner than other options that are only ~$10 more. Tilt mechanism: Major reason for my 3:5 stars. It's plastic with a metal fastener through the middle. We won't be tilting this umbrella in any wind gust situations over 5mph. The warnings on the stickers and in the instructions make it clear this is a limitation, but it's not mentioned in the listing details. Quality | Value for money: Overall very mid. This is a nice 3-tiered umbrella at a near rock-bottom budget price for that class. I have found other mystery brand umbrellas on Amazon that have lasted for 5+ years, albeit with some (in my opinion) acceptable fading and rust. This umbrella leans hard into plastic everywhere except the fasteners. The ribs and pole are almost as thin as a few layers of beer cans pressed together. At least at the 10' and up diameter, this umbrella requires you to install equally flimsy-feeling extensions in order to get to 10', full sail. Final thoughts: This time around I chose price + delivery speed over quality, and I have a hunch I will be getting what I paid for. I doubt this umbrella lasts for more than 2 to 3 years without UV treatments and a very solid, heavy base.

Excellent Value.
Color: Forest Green, Color: Forest Green
Excellent value. Well made. Assembles in a few minutes. Note that the tilt control is the single click type. You push a button on the support column and tilt the umbrella until it picks in place. Venting design is helpful in keeping umbrella from tipping over in moderate wind. Fabric is a light synthetic. We chose green which we like.

Love this umbrella!
Color: Lake Blue, Color: Lake Blue
I totally love my umbrella. The 10 foot size is perfect for the coverage I needed. The assembly was super easy. The Lake Blue color is more beautiful than the pictures displayed. UV coating is exactly what I need, after having skin cancer. It's also stable in light to moderate wind, thanks to the slits in each tiered layer, allowing wind to pass through. I've only had this umbrella a week, but am impressed at this point. It's much more cost effective than having either an awning or roof extension over my patio. $90 vs $8-20k! Highly recommended.

AMAZING PRODUCT!
I am so impressed by these! It’s winter and my skin has been so sensitive, dry, flaky patches… I’ve tried so many products! I saw a few videos of these being used decided since there were so many independent videos about them I’d try! O.M.G!!! I should have taken a before and after! After only 1 use my face feels sooo much better. No more dry, flakiness. They were extremely easy to use. I have a bit more of a round face and they fit just fine (went up a little higher on my hairline but not bad). Doesn’t leave your skin feeling sticky, just hydrated! 100% will buy again!
