First ride with my Design Cycles mount today.
Black Friday sale price was only £16, including shipping
Arrived in 5 days from US to UK
Good communications to provide order update throughout
Very solid interface between Garmin and mount - a very secure fit
Mounts perfectly in line with top of stem
No vibration or movement whatsoever during ride
Very aesthetically pleasing having the mounting hardware underneath
(Very minor) Negatives -
Contact with side of stem face place of 3T stem prevents Garmin from being centred exactly but it is only 1-2mm off and not noticeable on the move (though I may still consider notching the point of contact slightly with a round file to make it perfect).
Garmin sits slightly further forward of the stem face plate - about 5 to 10 mm - than I'd like ideally (photo below) but that really is a just a personal quibble.
Overall, very happy with my buying experience from Design Cycles and with the mount.
Well made, good looking mount that I would have no worries about the Garmin disengaging from and particularly good value for money at the $25 / £16 discounted price.
Definitely a bonus having the Garmin forward of the stem so that the screen can be seen with a quick glance, rather than a deliberate look when it is mounted on the stem - will definitely be looking to replicate the position on my other bikes.
