Thank you, thank you, thank you Charles for getting my gravel bike up to speed for my race this Saturday. Sadly, my bike slipped off the bike rack and the front wheel bent. Luckily, he had one I could borrow for the weekend - so my race is still on!!!

Congratulations to Mike Barro and his crew at 40K Cycles Stop by to see them in the Laboure Center on Highway K and see all the cool gadgets for your bike.

Few fun ones from Saturday! Cheers to 40K Cycles!! 🥃🍻🚵🏼🚴🏼‍♀️🎉

I volunteered this morning and took a few photos of the kayak portion of the race. https://www.facebook.com/media/set/?vanity=socialbirdmarketing&set=a.3263777673670099

Great job everyone! I hope to join and do the race next year!

John was involved in a bad accident 10 years ago. He was in pain and deteriorating to the point he could barely move. Then he discovered the bike again. Today he picked up his TREK E-Caliber MTB! You've come a long way. Congrats.
BTW We dig the colorway as well John.
