I built up an El Mar at the end of last year and have been riding it more and more of late; my first 29er and do like it... but it isn't half heavy and I do wonder if that weight adds to a sluggish ride. My riding is firmly two-wheels-on-the-ground and nothing particularly arduous - just local woodland trails and singletrack. I'd like to try something that is lighter and hopefully feels faster.
I do like Salsa bikes and have been pondering the Mamasita - I did consider the Kinesis FF29 but it is more expensive and not as light as the Mamasite. All parts could go straight over from the El Mar to a Mamasita, except the bottom bracket.
Does anyone have both or has gone from one to the other and could offer some qualified comments..?
