Too much Junk on the bike,,

You should have a Smart Phone with you for safety,,,, Get the Strava App' and your done...
Maps the ride, time, distance, by segment, charts your progress and your friends,, all for free... Spend $5 a month and It does more...
I see riders often, stopping and looking at their little computers during the ride to see how far they have come, ok ok thats fine.

But Try this just once, for me !
Turn the cell phone ringer off, make the thang silent. Start Strava, Stuff the thing deep In your pack, Loose the watch If you still wear one of those..
Now go ride the bike, When the sun starts getting low or you run out of water and food take It to the trail head,,THEN open Strava and see your numbers.

A computer on the handlebar ? Really ?
Bike bouncing down the single track, the crash,,

Now try and find that little thing,,

IMO you should not have anything mounted on the bar you don't need,,,

You will be tempted to look down at it.. And Right then and there you will learn that tree's can move real fast, roots too, and It's a game they play...
Knocking us off our bikes,,,yeah I have actually heard them laugh at me

My Mom used to take me for long walks In the woods,,,But I always found my way home,,,,,Made Dad so mad
