Got to brag somewhere Saturday I did the Piney Woods Purgatory in Lufkin, TX. 70 miles, 3,100' of elevation. Only three or four hard climbs but the rollers and short climbs never stopped-all up or down. Used 70". Averaged 15.5 with no drafting 'cause the geared riders kept dropping me on the steep downhills. Around 130 rpms and I scrub speed with the brakes. If I do it next year think I will ride a SS 70". Think I can tuck and keep up better on the downhills, but the climbs may be a bit harder.
