Blend Alloy
The frame consists of at least three different alloys, which together create the optimum combination of stiffness, strength and weight. Frame arts such as rockers and axles are made of 7075 T6 aluminium, which has a very high strength. For the tubes of the frame a more fatigue-resistant 6066 T6 aluminium is used. In addition, the milled and forged parts are made of 6061 T6 aluminium. Blend Alloy thus presents PROPAINS special and unique manufacturing process and ensures the optimum performance of the lightweight frames.

PR010 / Frame Protection
More agile and balanced than before, thanks to PRO10 suspension system. Since PROPAIN doubled the Anti Squat up to 120% comparing to the old model, PROPAIN set new standards with the Spindrift 4 AL. No matter if air or coil shock, the suspension system harmonizes with every setup and always provides optimal traction. Even on uphill rides, you will benefit from the PRO10 system, with prevents the suspension from compressing when pushing the pedals, so your front wheel does not rise even on steep climbs. The special developed down tube protector prevents the frame from damages.

Dirt Shields / ACROS Bearings / Internal Cable Routing
Better safe than sorry! The robust ACROS frame bearings are additionally protected by PROPAIN Dir-Sheilds and provide an extra seal that protects the bearings from dust, water and dirt. Clean cable routing for a nice look is a must. Special cable channels inside the frame ensure reduced noise and easier replacement of cables. The drive and brake cables run above the bottom bracket.

Clean & Modern
Thanks to the versatility of PROPAINS Blend Alloy THE Spindrift 4 AL also convinces with its elegant design. Many visible edges and flowing shapes paired with a futuristic logo guarantee envious looks on and off the trails.

New chainstay protection
High drops and hard landings can get your chain swinging pretty hard. Our newly designed chainstay protector absorbs them, eliminates noise and protects the chainstay from damage.

PROPAIN's well known PRO10 system has once again been further developed and improved for the Spindrift. The shock moved in front of the seat tube and is now ideally integrated in the main frame. So, the Spindrift is even more agile and more balanced. The combination of a slack headtube angle of 64.5° and a steep, effective seat angle of 78° ensures that you can climb the steepest climbs on a Freeride Bike without getting out of breath.

Great experience with Paul. Had an issue with my Fox X2, and sorted me with one of his EXT shocks in the time while a new part came from the UK. Really transparent service, explaining in details the issues and solutions. Chur!

"Proflow have been super important for me with bike setup. They're very professional and I love the fact they think outside the box to get the most out of suspension. I definitely couldn't have got my bike feeling the way it does without their help!"
