Expresso was the first trail i rode (~2002) after taking a 10 year break from mtn biking. it was also the first trail i rode on the shore. i got schooled. i loved the challenges and resulting stoke of riding Expresso's various moves. the line i mostly rode was pretty flowy as were most of the features but Expresso's purpose was also it's downfall - it was over too quick! tough call on whether to keep this aspect of the trail alive? hard to get away from it with Expresso's start and finish location IMO. would be cool to see some modern trail features like a pump/jump line on the traverses mixed in with the sweet fall-line goodness. just my .02…
i ride a 26 and a 29 and i do like the idea of 650b… however, if the rim diameter is only 25mm wider, the radius is only 12.5mm more… 1.2cms!!! all this debate over 1.2cms!… tall/high volume tires can probably cover 1/2 of that so now we are talking about 6mm… with all the variables and elements in mtn biking - terrain, traction conditions, rider skill, suspension settings, geometry, etc. - I would think 6mm is irrelevant…
and i certainly sympathize with manufacturers - new products cost money to develop and sales volumes on 650B will likely just canilbalize 26" sales… but if a manufacturer doesn't develop a 650B product, they stand to lose sales… but save on the R[HTML_REMOVED]D costs… its a cost/benefit decision for them…
BTW - i think 650B rims are 584mm… not 590mm
Wow, I am long-winded sometimes.
For the record, after a year on the tallboy I am still very impressed, though it's gained some weight - fox 34, Angleset, heavier rims/tires.
I suspect there will be a bunch of 140mm 29ers coming, then in 2013 everyone will be distracted by the 650b's.
yo clark, curious where u run that 34 on the TB… 120? talas? 1 degree slacker or more with the angleset? i'm liking the look of the kona, yeti and transition 130mm bikes. loving the 100m HT yeti BT 29 but want a bigger bike…
as pointed out above, if the outside diameter of a 650b rim with a pinner tire is the same as a 26" rim with a large volume tire (ie. both barely clear frame/fork), it's hard to imagine there is much (if any) performance difference due to wheel size. tire and rim selection would be the deciding factor for me but i haven't ridden a 650b… but have spent a lot of time on my 29r
common reasons for not making a climb:
- spinning out/lack of traction
- technical obstacle
- lack of power
what helps me:
- look ahead and anticipate where you will have the least amount of traction and plan accordingly. sometimes that means threading the needle for a line choice with more traction but most of the time it means you need to be carrying more speed BEFORE you hit the low traction/slippery zone and use your momentum
- spin when there is traction or to manage energy, use power when you need speed and momentum to get up/over areas with less traction
- for really technical obstacles (think 50M east of expresso/BP/dempsey intersection on BP), it's a combination of having enough speed before you hit the obstacle, being in a gear that has traction and thus helps carry your momentum and having the body english to power over something when needed
i love DH and descending but also love the challenges of technical climbing. lighter gear (wheels and tires) helps with climbing speed, acceleration and requires less power.
IMO rear suspension requires more power but helps with traction. 29rs are an advantage for climbing due to better traction and momentum
competitive cyclist was blowing out a few of those as part of their demo sale a few months back. numbers look good; the want was strong
yeah i couldn't say no to the end of season deal i got in the fall… new frame/fork and headset combo…
i ran a totem for a while. definitely made the bike feel invincible. had a CCDB coil as well which i loved on there. now running 170mm lyrik air and RP23. certainly a trade off. stiffer feel with air setup, not as forgiving as coil/totem, 2+ lbs lighter, climbs better thou and is overall a faster "trail" bike. the suspension setup and fork travel can noticeably change the geometry of the bike IMO. i'm running a 10mm stack lower cup 1.5 headset to minimize front end height with the 170mm fork and don't have talas. still climbs like a goat.
light - yes. mine are 1600g.
strong - i wouldn't say they are the strongest rim. more of a race set or wheel that frequently requires truing and a new rim once a season or so.
flexy - oh yeah!
i've got a set on my 29r HT and they FLY!
To be clear, I'm not trying to make my xc bike into a dh machine. It's ridiculous what we're riding on the tallboy, but I'm curious if I can boost it's descending capabilities even more without harming it's climbing/cornering characteristics.
i was thinking the same thing on the WE… basically taking the opposite approach to building a 29r vs. say a 26 AM ride like say a nomad. IMO the nomad's strength is descending so it's easy to improve the bikes climbing characteristics in how you build it… 29r's climb so damn good, i would think it's easy to improve their descending characteristics in how you build it too…
