2013 Timberline 1.0

The one bike that does it all. Are you driving yourself crazy trying to decide between a rugged trail-ready bike and something reliable to commute around town on? Who says you can’t have just one bike that does it all? The Timberline spans the gap between the two so you get the best of both worlds: durability and control on the trail with the comfort and dependability on the road that GT is known for.

        Mostly a road cyclist, I was looking for a good 29er hard tail for my occasional trail riding. I currently have an Aggressor 1.0 that my daughter has fallen in love with and claimed hence my search for a new trail bike.

        In November, 2012 when I saw this one for under five bills on sale I took a hard look to see what was wrong with it. The short answer is not very much. A few compromises to keep the price down (tires are cheapest possible, disks are mechanical, and the fork has limited travel) but for my use I don't need a top of the line fork (just one with lockout)and I threw in some tube liners for now and will end up upgrading the tires anyhow.

        Grupo is same as my Aggressor (a little over 1k miles on it and I've adjusted the brake and derailer cables only twice) and disks are fine. I easily can lock up the front wheel and skid to a halt on trail or stand it on it's nose on the road so plenty of stopping power. Plenty of control in between those extremes as well.

        Mine is matte black with dark gray lettering, really stealth fighter looking. My Aggressor was a large frame and I added a longer stem to compensate. I went with an XL frame for the Timberline and at 6' 2" 240 lbs. 33" inseam it fits me perfectly.

        I've only put about 15 miles on it so far, but that's enough to get it dialed in and see that I'm going to like this bad boy a lot - a WHOLE lot.

        I can see the price going up on this so if you'r e in the market, take a look pretty quick at this bike. They're going to have to raise the price. I don't see how they can keep selling it at the price point it's at. I also don't see how for us more casual riders they will ever sell a Karakoram 4.0, 3.0 again, and loose some 2.0 sales as well. 20mm of fork travel is not a big deal for most of us honestly and that is really the biggest difference for us more casual trail riders. They may drop this one to avoid cannabalizing sales of the higher priced model!

        I purchased the bike a few weeks ago and I was happy with it at first for my usual semi aggressive downhill trails and around town rides but the minute I hit anything aggressive I started replacing parts. I know the bike wasn't designed for super aggressive downhill or anything but it was on sale for a great price so I purchased it knowing I would need to replace parts. First, I bent a handlebar, next I bent the crank and bottom bracket, next, 2 bent rims and punctured tire, next a snapped headset, and lastly collapsed forks. Also I'd recommend replacing the tires if attempting any loosely packed trails. So basically it's a great bike for anybody looking for an all purpose bike. Elsewise, if you ride more aggressive trails such as myself, expect to put some money into the bike. With that said, post upgrades, I am extremely happy with the bike.

                    I use this bike to get around town and also in my weekly trail ride. I rode the bike home from the store and I could not believe how smooth it is and how sturdy it was. It being on sale for a super.low price help also. The bike is very well equiped, the front fork is super smooth, the deraillers are great and so is the frame. This is a great bike and I would recomend it to any one that needs an all purpose bike! Happy trails!

                          Bought this bike last february and until now I haven't change a part. I use it on trails and long rides. This bike is fast and can compete with other expensive bikes. Also the price is good knowing its a 29er and its a great entryl level bike.

                          Soon I'll be upgrading the tires if worn out, to better suit it for the trails. I have the Lime Green.. Enjoy! :)

                                I got this to ride around town with the kids and to do the occasional loop on the fire road nearby. Here we have nothing but hills and few flats. The bike climbs like a champ. It isn't a killer to peddle on the street either. The huge tires easily cross small culverts and ditches with confidence. I'm not doing any crazy single track, but it'll handle nasty logging roads with ease. So far so good.

                                      Haven't ridden for 10 years. Got this to mostly ride on roads and parks but occasionally on fire roads. We live in very hilly country and was very impressed how easily this bike climbs. The huge tires cross small ditches and culverts easily. So far so good.

                                            Let me start off by saying this bike is amazing and fits me perfectly. Me and my girlfriend had bought a couple bikes one day. Well me never having a mountain bike I just went with w.e. but my bike didn't fit me properly, so I started looking at gt as I use to have a bmx bike from them. So I went into the store and immediately this bike caught my eye. The color scheme, size and over all look. So after talking to the sales guy I purchased the bike. Wow my very first ride I was so impressed with how comfortable it was, the shocks didn't bottom out, the bike handled amazing. I really can't say enough about this bike, if your thinking about purchasing this one, trust me you won't be disappointed! !!!!!

                                                  Great 29er for the money. Needed to change the pedals and grips and might put a beefier longer travel fork on it. But this thing is nice. This is my first 29er so it took some getting used to but after about 30 min I adjusted and I'm seeing good results. 29" rims seems to make things easier.

                                                        I just bought this bike in silver a week ago and it rides very smooth. I'm 6'1 245 pounds and got the large frame. I would say it fits perfect. Very happy with my purchase. The only thing I didn't like about the bike is the seat. Is not comfortable. Beside the seat, this bike rocks. Great price!

                                                              I bought this bike as a replacement for my old 26" mountain bike and my road bike. I wanted a legitimate mountain bike for hitting the trails, but also needed something to cruise around town on. I'm very pleased with this purchase. I'm a 5'8" 160 lb male and the small frame was the best fit for me... unfortunately I had to wait 2 weeks while it was on order but at least I got the right size.

                                                              It is great on the paved bike trail with my 11-month old son in his Weeride, but also handles great on single-track in the woods. I've only had it for a few weeks but I've ridden it every day and have no complaints. The disc brakes rub a bit in the back, but I'll adjust them soon. The shock is nice and the lockout comes in handy if you need it.

                                                              The tires it came with are not beefy MTB tires as I would prefer, but the hybrid tires are actually probably better for my current tame rides on the bike path. Overall, I'm very happy with this bike and would recommend it as a cost-effective entry-level 29er for a casual road and MTB rider.

                                                                    Mostly a road cyclist, I was looking for a good 29er hard tail for my occasional trail riding. I currently have an Aggressor 1.0 that my daughter has fallen in love with and claimed hence my search for a new trail bike.

                                                                    In November, 2012 when I saw this one for under five bills on sale I took a hard look to see what was wrong with it. The short answer is not very much. A few compromises to keep the price down (tires are cheapest possible, disks are mechanical, and the fork has limited travel) but for my use I don't need a top of the line fork (just one with lockout)and I threw in some tube liners for now and will end up upgrading the tires anyhow.

                                                                    Grupo is same as my Aggressor (a little over 1k miles on it and I've adjusted the brake and derailer cables only twice) and disks are fine. I easily can lock up the front wheel and skid to a halt on trail or stand it on it's nose on the road so plenty of stopping power. Plenty of control in between those extremes as well.

                                                                    Mine is matte black with dark gray lettering, really stealth fighter looking. My Aggressor was a large frame and I added a longer stem to compensate. I went with an XL frame for the Timberline and at 6' 2" 240 lbs. 33" inseam it fits me perfectly.

                                                                    I've only put about 15 miles on it so far, but that's enough to get it dialed in and see that I'm going to like this bad boy a lot - a WHOLE lot.

                                                                    I can see the price going up on this so if you'r e in the market, take a look pretty quick at this bike. They're going to have to raise the price. I don't see how they can keep selling it at the price point it's at. I also don't see how for us more casual riders they will ever sell a Karakoram 4.0, 3.0 again, and loose some 2.0 sales as well. 20mm of fork travel is not a big deal for most of us honestly and that is really the biggest difference for us more casual trail riders. They may drop this one to avoid cannabalizing sales of the higher priced model!
