CNC Singlespeed Cassette Hub Spacers - Anodized red, blue, Purple, Random mixed set.

Please note colour shades may differ due to variances in the anodizing process. 

We have also added into this listing a final limited number of gold sets.  Each kit contains 8 or 9 assorted spacers in 2.5/4.5/5.5/6.5mm but without the 7.5mm engraved spacer and a limited number of random colour sets (last few now!) in a choice of engraved or not.


NOTE: This sale is for one set of seven brand new spacers as above. SPACER KIT ONLY!  Cog, hub and lockring etc are *NOT* included.
  • CNC custom machined in the UK exclusively for VeloSolo from solid lengths of 6082 aluminium alloy - not cut from tube. Superb quality.
  • Thousands sold Worldwide since 2007.
  • Note: kit is designed for virtually all 7/8/9/10/11 speed hubs and will fit over 99% of hubs.  IMPORTANT: many newer 11 speed (Hope Pro 4 etc) hubs (and rarely some 10 speed road hubs) have a wider freehub for the wider 11 speed cassette and an additional 2.5mm spacer may be required *IF* using a narrow 2mm single cog (this spacer often comes with the hub itself).  We can supply this at minimal extra cost (contact us for details or request at time of order).  If using a wider 4mm single cog (Andel, Surly etc) this will not be needed.  Our kit is NOT compatible with certain DURA ACE hubs (7800 etc).
  • Now available anodized in custom colours with largest spacer laser etched. Choose from black, red, blue, gold, green, orange (metallic 'burnt' orange), 'Titanium' blue/grey, 'Magnesium Bronze or special edition 'Rasta' mix of red/gold/green or 'Patriot' in red/'white'/blue. New colour purple now available too.  Also Italian red/white/green (white=silver) and black/gold/red that can be configured as Belgium or Germany.
  • New colours 'Titanium' blue/grey, and 'Magnesium' Bronze! And new anodized silver.
  • Limited number of 'random mix' spacers at special price (while stocks last!) now available. Each kit is a similar spec to the other kits but may include a slightly different mix of spacers with the choice of an engraved spacer or not and in a random mix of assorted colours.
  • This kit allows any 6, 7, 8, 9, 10*, 11* speed MTB or road (*10/11 speed SEE NOTE above) Shimano pattern cassette hub (eg Hope, Mavic, DT Swiss, Chris King, DMR, Halo, Nuke Proof etc) to be used with any single cog.
  • Works with the thinnest cassette type cog to the fattest Surly. (14t, 16t or 18t Shimano DX-R singlespeed cogs available in our eBay shop as well as high spec Andel SS cogs.)
  • Pack of 7 includes 1 of 7.5mm, 1 of 6.5mm, 1 of 5.5mm, 2 of 4.5mm and 2 of 2.5mm spacers. Simply add cog and lockring (available in our other listings).
  • Unlike two wide spacers in basic SS kits, this combination of seven spacers in five narrow widths allows precise fine tuning of rear chainline.
  • Use with single, dual, triple cog set-ups. Perfect for matching chainline on both sides of a mountain bike fixed/free flip/flop hub - this is a very adaptable kit.

This sale is for one set of seven brand new spacers as above. SPACER KIT ONLY!  Cog, hub and lockring etc are NOT included.

NOTE: photos show all colours available - this sale is for one set. Some photos show earlier samples without laser engraving. All sets have the 7.5mm spacer engraved as per first photos unless otherwise noted.
