While full suspension bikes deliver impressive characteristics, the classic hardtail endures as a pure and effective tool. Our 29er wheel-equipped BIG.NINE range offers both carbon and aluminum constructions, along with diverse geometry choices. The refreshed CF carbon and LITE aluminum-framed BIG.NINE models feature modern geometry with improved standover clearance and handling stability, designed to better tackle the tough race tracks of today. Additionally, downcountry-ready TR options provide increased fork travel, aggressive tires, and dropper posts.

Our classic hardtails are foundational to our product lineup, showcasing the deep wealth of experience and knowledge gained from over half a century of bike manufacturing. The BIG.NINE range represents the symbiosis between cutting-edge frame technology, meticulous attention to detail, and the craftsmanship 'Made in Taiwan' symbolises.

TDI Seems To Like This Stuff. A Must For US D2 Fuel.
Size: 1 Count (Pack of 1)
After purchasing our 2012 VW TDI diesel at 140K miles I started researching best practices to keep these little engines happy. What I read was that the US has some of the crappiest quality D2 diesel on the world stage. Even Canada's diesel is higher cetane and lubricity rated than the States not to even mention Europe which has WAY higher standards than us. The weak point of these TDI engines seems to be the high pressure fuel pump (HPFP) that is crank driven to enormous pressure for the injectors to to their thing. If these HPFP parts fail on common rail engines they can literally grenade and throw shards of metal everywhere within the downstream fuel system ensuring a VERY expensive repair if not destroying the engine altogether. The lubricating property of the fuel plays an important part in keeping these pumps working properly. There even seems to be some data supporting Canadian operated TDIs have fewer failure rates of the HPFP than stateside fueled vehicles although nothing had been officially published to my knowledge. Sulpher in the diesel had beneficial lubricating properties but was bad for the environment and subsequently removed from D2 by the EPA much like leaded gasoline of yesteryear. So the second tank I ran in my TDI was Hot Shot's EDT. I can't comment on the comparative difference as I ran this from almost day one. What I like is the claimed increased lubricity and cetane boost that is supposed to bring our crappy D2 up to reasonable levels the rest of the world enjoys. Fuel economy seems fine but playing with a low spun turbo and the subsequent torque is sometimes too irresistible to give fuel economy a fair chance. Besides, I need to blow out all that accumulated carbon :) I like the fact that the Hotshot's EDT seems more concentrated and affordable than the competition. 1oz for a tank is almost a performance treatment for my TDI. It's a negligible cost for a fill up and I hope they keep it that way. My dislike might be the one thing other people love about this product and that's the bottle. The bottle is meant to be squeezed to get the measured amount in the top fill area so measuring is easier. My concern is the filler neck is not long enough to cram into the filler to avoid spilling without a funnel and diesel doesn't do many favors to paint. My workaround was to save the empty bottles from other gasoline treatments and use a syringe to fill 1oz amounts of EDT and place in the trunk of the car in double plastic bags. Seems to work fine although the kitchen was probably not the best place to do this since it doesn't smell like flowers. Next purchase will likely be the bulk bottle. It's kind of a shame we actually need this kind of protection now since the US fuel standards are almost non-existent. Even B1 blended bio diesel would be a huge improvement in lubricity but not available where I live. Thanks Hotshot's...Good stuff!

Recommended by John. So far great additive for the CP4
Size: 16 Fl Oz (Pack of 2)
I have a ‘22 6.7 Powerstroke w/27k and pull heavy trailers in FLA. I’m worried about the (disco party). John I believe from the Ford Dealer in Hereford, Tx recommended this. I run 2 oz per fill and will see what happens. I’ve got Five fill ups on it now and seems to help responsiveness. Proof will be in the pudding. So far I’m pleased

Quieter and more mpg in TDI
Size: 1 Count (Pack of 1)
Didn't really believe the hype. Did a little research and watched Project Farm and decided to try. Im not a snake oil guy....but I will say my 2013 common rail TDI is quieter and I get a tad more fuel mileage. Does it pay for itself? Well, it does get better mpg, but I feel the reduction in noise most likely relates to less wear and tear and thats good enough for me. Im only using 1oz per fill up (about 14 gallons) so it lasts a very long time. I get 40mpg and im not light footed.
