On-One Bikes (United Kingdom) - Press Release: The BigDog is our progressive 29er steel hardtail. Designed for British conditions, big days out, sessions in the woods, and everything in between.

• Double Butted 4130
• SRAM SX Eagle 1x12 Groupset
• 29er wheelset

On-One invented the hardcore hardtail with the Inbred and 456 models that launched the brand - doing things differently 20 years ago. The Big Dog is a perfect progression of that packing 29in wheels into a chromoly hand welded frame that give up to date handling at an incredible price.

Triple and double butted 4130 tubing, hand TIG welded into a contemporary chassis, with routing for 1x drivetrain and stealth dropper post.

The 44mm headtube takes tapered forks and keeps things tidy and easily upgradeable. A threaded BSA bottom bracket shell means no creaks or weird workshop confusion. A 12mm though axle rear dropout sits at Boost 148 spacing to get the best tyre clearance and wheel strength and stay bang up to date.

A tough chainstay plate means great tyre and chainring clearance and extra durability too.

Gussetted top and down tubes keep the front of the frame strong, and let us use optimised main tubes for better handling.

The Big Dog 29 comes in four sizes with contemporary reach dimensions for riders looking for that long, low feel with a short stem. It's set to be a classic.

Paint finish includes a Phosphate and Laquer version which will rust in use, but we love it. If you're disturbed by less than perfect finishes, it's best you avoid this.

Fork - Rock Shox 35 Gold has same size stanchions as a Lyrik so it tracks super-well in the rough. 130mm is spot on for 29in wheels so the front end doesn't get too high.

Groupset: SRAM SX Eagle 1x12. SRAM's entry level Eagle groupset packs in 12 gears, a huge gear ratio and the best chain retention and gear shifting that you simply won't believe how good these new groupsets have got.

Wheelset: BOOST spaced wheelset, built for some fun, rough and tumble and mile after mile longevity. 29ers roll a little faster, offer more stability and gobble up the trails.
