Hello,

I'm refurbishing my bike and want to replace the old Kinect center 68x123 _ square with this one. Will it fit? Are the nuts in the package? Will the Shimano 3x8 48-28 cranks fit / use Trek. Now I have 44- 24. Thanks

SK Dobry den,

viete identifikovat akeho standardu mate povodny stred - ISO alebo JIS? Pokial JIS, tak by podla popisu tento stred na Vas setup mal sadnut. Sucastou balenia su aj skrutky FSA ML016 M8 x 1.0 x 16.5 mm.

Hello.
I currently have a UN300 BSA 68x124.5mm axle on my bike. Will this part be compatible?
Thank you for the info.

SK Dobrý deň,
ide o rovnaký rozmer 68x124.5mm, takže by malo byť kompatibilné.
