|Maxxis' Minion tire, the DHF in particular, is a proven winner, one that works well in nearly all conditions, providing excellent grip no matter how nasty the terrain. You mention that you already have a Minion in the back, but don't mention whether it's the DHF or DHR tread pattern. In either case, I'd recommend purchasing a Minion DHF to accompany it as a front tire. It's perfectly fine to run the DHF in both the front and the rear (a setup I prefer due to the slightly faster rolling speed when compared to the DHR), so when that rear tire gets too worn you can rotate the front tire to the back and replace it with another DHF. I think you'll be pleasantly surprised by the improved performance that the DHF provides over the Nevegal. - Mike Kazimer|
There's a reason the Minion remains a favorite of all-mountain and DH riders - predictable traction no matter the conditions.
|Some 27.5-inch wheel and tire combinations will fit inside "select" 26-inch forks, and there is a slim chance that the same combinations can be shoe-horned into the Knolly's swingarm. Doing so, however, would not be a good choice for a number of reasons. First, your only positive gain would be a slight decrease in rolling resistance over choppy terrain. Your tire selection would be limited to smaller versions of the brands you prefer or anemic cross-country models. Also, the stock fork will not have offset corrected for the larger hoops. Even if the Knolly did fit a 27.5-inch rear wheel and you purchased a 27.5-inch fork, switching to larger-diameter wheels will raise the bike's bottom bracket to a less-than-optimal height. The 26-inch-wheel Knolly Endorphin is one of the better-handling trailbikes made, so leave it at 26 and enjoy the ride. I'd suggest converting it to tubeless and spending a small sum on a fast-rolling set of large-volume tires - two improvements that will dramatically improve the Knolly's roll-over performance in addition to boosting its handling in every other trail situation. - RC|

| As you discovered, the majority of coil springs are only available in increments of 50 pounds. You must weigh very little to require such a light spring, but in your case, the stiffer, 300-pound option would be best because, in an ideal world, no preload on the spring is optimal and will give the best performance. The perfect spring would let your rear suspension sag exactly right, with just enough preload to keep it from rattling between the collars. Our resident Demo Tech says more than two full rotations of spring preload is approaching too much. So, it seems like you have two options for your Demo:|
Buy the lighter 300-pound spring from your local shop, and it should produce your desired sag measurement. Or, purchase the lighter, 250-pound spring and hope you can preload it to your proper sag setting without causing it to coil-bind.
Coil-bind means that the spring reaches maximum compression and the coils bottom against each other before the shock reaches full travel. This is a big no-no and could result in damage. Too much preload leads to harshness in the ride and allows the shock to bottom out too easily. If the 300 is too stiff and the 250 won't provide enough support, then you will need to source a 275-pound spring.
Springs in 25-pound increments are available from Ti-Springs.com. They only offer titanium springs, which will save some weight, but at a premium expense. Expect to pay around $159 for their basic Ti spring - colors are additional. Remember, when purchasing a spring, you'll need three numbers: the spring rate in pounds-per-inch, followed by the spring's rated compression length in inches. Both are printed on the coils (ie: 300 x 3), and you must also order the inside diameter of the coils to match the new spring with your Cane Creek shock's collars. That info will be provided by the spring maker. - Paul Aston
The best spring is the one that allows you to achieve your ideal suspension sag value with the least amount of preload. Sometimes that may mean ponying up for titanium.
