Thanks all, useful stuff. I currently get toe overlap on my 29er (I’m 5′ 9″ with mahoosive size 11 feet), but this design increases the top tube by approx 1cm and slackens the HA which may alleviate that.
I wish I knew how to work out the trail figure…I’ll google it 🙂
Ok, I googled it, and according to this site, with a 2.2 inch tyre, I’m looking at a trail of 83mm. I have no idea how to interpret that though!
The BB drop is something I’m still working out so I’ve estimated for now.
I’ve been riding a 29er exclusively for nearly a year now, and am currently on a 2nd (borrowed) 29er. It’s the difference in the ride between the two that’s got me thinking of designing my own ideal solution. I wish there were more opportunities to test 29ers…and sadly I can’t make Charlie’s beach party on the 25th!
