A lot of controversy and argument has surrounded the release of the 15mm QR thru axle from Shimano and Fox. I had the opportunity to throw the new 20mm thru axles from Shimano/Fox and Rock Shox on the Ultimate scale and here are the results.
The big news here is that the 120mm Reba rumors are true. This will make a lot of riders very happy in the 29er and 26er market. With the increased travel on the Revelation and 20mm option…you have to wonder…what will happen to the Pike line? I guess we will find out soon enough, but in the meantime…SRAM continues to raise the bar in suspension forks. ’08/’09 should be extremely exciting.
Everyone that is saying that 15mm is going to be lighter than 20mm has no engineering background at all. All things created equal…the difference with the same materials and parts would at most be several grams…and this small difference would not be felt on the bike when it is actually ridden.
