I have had 2 six packs and and had the reflex for a year now and love it it’s brighter and seems to have a better flood,it’s nice to see how long you have left on the back aswell,I was going to sell my mk1 to get the mk2 but exposure told me there was no difference really so did not bother,you can get the mk1 for £320 on ebay from rutland cycles or email ant from the XC racer shop I bet he will match it.
