Kitted out with a 300 Series Alpha Aluminium frame, the Checkpoint ALR 4 is just as responsive on chunky gravel roads as it is smooth on the tarmac. Tons of features like tubeless-ready wheels, a SRAM Apex 11-speed drivetrain and mechanical disc brakes make Checkpoint ALR 4 the perfect ride for ease of entry into the wide world of gravel.\nIt's right for you if...You're ready for adventures beyond the beaten path and want a gravel bike that balances budget and capability. The Checkpoint ALR 4 is your ticket to turning every ride into an adventure.\nThe tech you getA responsive 300 Series Alpha Aluminium frame, hidden cables that won't interfere with bags, integrated rack, mudguard and frame bag mounts, a 1x11 speed SRAM Apex drivetrain for smooth shifting on punchy climbs and variable terrain, mechanical disc brakes for ease of stopping quick in all conditions, tubeless-ready rims and wide Bontrager Girona Pro 700x42c gravel tyres for added comfort and traction.\nThe final wordIf you're ready to start exploring every road while taking on the daily grind, the Checkpoint ALR 4 is the ride for you. Versatility is the name of the game and a durable alloy frame, mounts for all kinds of accessories and wide tyres make for comfort and customisation wherever the road, or lack thereof, takes you.\nHow tall are you?To measure your height, stand up straight, barefoot, with your back, heels, shoulders and head all touching a wall. While looking straight ahead, place a book or straight edge on your head and slowly push it against the wall. Your straight edge should be parallel with the floor. Mark the spot where the bottom of the book is touching the wall. The distance from the marked spot to the floor is your height.\nWhat is your inside leg?How to measure: Stand barefoot with your back straight and against a wall. Tuck a ruler or something that extends to the floor between your legs. Using both hands, and keeping it level, pull the ruler up into your crotch as if you were sitting on the saddle. Measure the distance from the top edge of the ruler to\n\n\n\n\n\n\n\nSize\nRider Height\nInseam\n\n\n\n\n49\n\n156 - 163 cm\n5'1\" - 5'4\"\n\n\n74 - 77 cm\n29\" - 30\"\n\n\n\n52\n\n163 - 168 cm\n5'4\" -
