Can you convert from R to RC2 and can you convert from van to float or talas? will save me buying v expensive new ones!

You can convert to rc2 by buying a new damping cartridge but they're about £200 to buy so probably be cheaper to sell yours and buy some new ones especially if you want to go air as well.

The other option would be to get some from ebay with cracked lowers and swop the bits over.

Trigger's broom.

Theseus's ship.

I've had this broom 15-years. Its had 15 new heads and six new handles.

talas and float are interchangable. Vanilla is different.

Yes you can buy the RC2 damper separately.

personally I thing the R damper is plenty good enough, and the vanilla is the best performing spring.
