Yes it is.
But you cant buy the parts…
I contacted Extra when I ‘lost’ the spring out of one of my pairs of MX8’s and they replaced FOC. Even although they were out of warranty. So, top marks to Extra but Time pedals have gone downhill in recent years and the top end pedals are ludicrously over priced for what they are.The axle which holds the springs is knurled at each end. However, this isn’t enough to stop the twisting action on the spring walking the axle out of the resin body. Then you lose the spring…
This has now happened to me on two pairs of MX8’s and a pair of Mavics ( Time licenced the design to Mavic for a few years but they’ve since dropped the range) In my view there’s an inherent design weakness.
Personally I’d just buy a pair of the old Time pedals ( the resin ones) that come up on ebay all the err.. time. That product was bombproof.
