Title: 890 - 1020
Post by: Gary72 on May 09, 2012, 07:48 PM: What's the difference ? Is it size? Has anyone got pics of both side by side?
I've got an 890, But having trouble finding another. Loads of 1020's on the bay

Post by: meticulous on May 09, 2012, 08:16 PM: the numbers refer to millimetres reach.

Post by: hunterdubber on May 09, 2012, 08:32 PM: Gaz it's reach from the cetre fixing to the end of the brake block slots .

Same number refer to all breaks ,, that's why you need a MX1000 for a PK Ripper because a MX900 is too short to reach :daumenhoch:

Post by: Spen69 on May 17, 2012, 08:17 AM: Yep, been through this a few times but an 890 measures 89mm from centre of spindle to centre of brake block in the furthest posititon. So a 1020 is 102mm, an MX1000 is 100mm and it also applies as you get smaller so a 610 is only 61mm (used for minis with 1-3/8" rims).

I've also had a few 1080's which I imagine would really help out out you Ripper builders..... Thinking about it, it was Ash who had them off me...... ;-)
