With a trip to the Dolomites starting in 8 days time I needed to work out a way to fix my Garmin 276C to the bike. I've seen some RAM mounts which seem to work but which work but which seem potentially to obscure the instrument display. The Garmin also needed to clear the little HP2 Sport tank bag. So we fixed on the following solution:
First, standard view incorporating the tank bag:
Now without the tank bag fitted and looking down at the two bolt holes which help secure the tank to the frame in front of the front suspension adjuster - with bolts removed:
Next the bracket, first top view:
Then bottom view:
The bracket is made from a piece of billet aluminium - 3mm thick and 3cm wide at the bottom. There are two cuts made in it to allow the aluminium to be bent to the correct angles. When the angles have been bent to suit, the cuts are welded. For info the bottom angle - where the bolts go - is about 45 degrees and the top angle - just below the GPS attachment - is about 80 degrees.
The bolts at the bottom are standard M6 size and we replaced the standard Torx bolts with Allen keyed bolts. The two bolt holes are centred at 1.5cm and the two slots in the mount are cut a fraction wider.
The GPS attachment is the deck fitting for a 276C and is bolted through the mount.
Here's the mount in place with the 276C fitted:
And from a side angle:
And finally with the tank bag fitted:
A friend with a small engineering business fabricated this for me. I will send the dimensions to anyone who is interested. Broadly there is about 3 cm to the bottom bend and then about 15 cm to the top bend. The top bit will need to be shaped to fit whatever base plate comes with your GPS.
