While building LaVita bikes we found the Sunshine brand. These are top quality cassettes and have been independently reviewed as long lasting and clean shifting.
After we started importing these for our bikes, south London bikes shops asked if we could get more and we now offer a complete trade service for cassettes of all common sizes from 8 - 11 speed. Please contact us for information about our trade service.
"These seem really long lasting." "I would definitely buy these again."
Note these cassettes are NOT the same as ZTTOs; this is a distinct brand that looks different and we have tested these cassettes for reliability and durability. These have been well received by our bike shop customers and we're happy for new trade customers to speak to our existing shops.
