Having picked up my new Brompton CHPT3, & really enjoying the short about-city evening ride to dinner, the next day Mrs Aussie & I just had to get out for an appraisal/comparison session. Sydney Olympic Park was the venue for Clarence & Rudolph to cruise about.
No major hills around SOP but I’m still limited (heart-wise) in being able to keep Mrs Aussie in sight (my usual answer is to ride Ralph-e, my Brompton Alfine GrinTech-electric model). However, my pace on Rudolph really surprised me & the lively & lightweight ride was a delight in being able to keep up comfortably? (A swap to Clarence for a time wasn’t a good idea; my extra speed was gone but Mrs Aussie also appreciated the effortless performance from Rudolph.)
Reflecting on the experience was difficult. I rarely ride a Brompton without loaded front-luggage & Marathon tyres. Did the lightweight Brompton & Schwalbe One tyres make that much difference? More appraisal obviously required, although my too-brief attempt near home the next day with both Bromptons with & without luggage was inconclusive, although Rudolph seemed superior?
yes the ordinary model marathons are sluggish and really slow you down. but they have good puncture protection, and a rubber compund that gives good grip in snow and ice. i use them only for that.
new brommies come with a lighter marathon race edition, have not tried those. then there is also a marathon plus model.
