Re: how comfortable is your bike?
The basic comfort is the one aspect I haven't given over to the efficiency I bring from road racing-
I use a good BEll cruiser saddle on eveything right now- even my 67 Peugeot PX10 roadbike- It's fairly wide and padded and surprisingly light-
On the motor bikes I always us a sprung seat post as well- between the two I never have any tush problems
One build I have a shock fork and the slower 50 still has a regular fork- the suspension fork is heavy, but really smooths things out and I think may help you stay ahold of the bars- alloy BMX 8 inch rise with a perpendicular grip- A lower bar would get a little more speed but I don't need it- but VERY comfortable- I ride alloy BMX bars on the roadbike now even- because I have back problems - I grew up largely riding a Sting Ray and really like em!
