Re: Specific heat absorption capacity of disc brakes

Im thinking all brakes are extremity sensitive to their levers pull not so much RB in particular more so in the same way as other brakes and levers are effected. When reading up on RB's I had found people were quite happy using long pull v-brake levers with RB's some defending them as superior as th...

As you can reduce air pressure and gain traction in 4x4's it probably works with bicycles .

Re: Specific heat absorption capacity of disc brakes

The mechanics of the TRP are a superior design to the bb7's which despite their short comings have worked well for people as the online reviews denote. If I had know of them I may well of went with the below hy / rd version that is reported to have a improved response. It weighs in heavy for those w...

Re: Specific heat absorption capacity of disc brakes

I bought a set of Nexus brake levers for the roller brake , they have a switch for long or short pull brakes. Found out I will also need to use them in short pull mode with the Spyre caliper as its made for cyclocross bikes with short pull levers. see article ~ http://www.cxmagazine.com/trp-new-spyr...

for a change of pace and improved all weather braking I deiced to swap out the v-brakes and picked up a nexus IM55 roller brake and a TRP spyre mech disc for the manitou fork. Im happy to be moving away from v-brakes for the ebuild as the faster you cruise the more important the stopping distance be...

Re: Specific heat absorption capacity of disc brakes

They were selling the TRP Spyre with 160mm Rotor for $50 on eBay so I ordered it. For Mechanical disc's the reviews point toward the BB7 spyre or the Klamper with the spyre reported as the best value. http://chainreactioncycles.scene7.com/is/image/ChainReactionCycles/prod143623_IMGSET?wid=500&hei=505

Re: Using the Wangdd22 1500W 30A DC Boost Converter on an ebike

I have a idea , they ran out of parts mid stream of production and ended up slamming out a whack of under rated units !
Or they designed two price points in their units ..I can find a 1200w for $18 ca. compared to $30 for the 1500w

Cool. If you don't like it, don't give up on roller brakes. Just try one of the bigger models. This one is a models with a lager brake and it has a @ 140mm cooling disc its no slouch in the cooling department. Its in the same family as the 80 and 81 they share the same instruction set.

Re: Using the Wangdd22 1500W 30A DC Boost Converter on an ebike

I will try the 1200w enclosure version its about the perfect size for the 350w motor if it gets hot can add a 2nd and 3rd fan and a few heatsinks to the chips , be nice to get its spec rating.

Both that one and the other digital tube I looked at are rated at 85% efficiency which blows as I really like that feature .

Re: Using the Wangdd22 1500W 30A DC Boost Converter on an ebike

Im thinking the 30A version with its 20A output would tempt me to use it's power and cook the motor .. whereas the 1200w version would act as a power limiter up near the top of its performance capabilities. 48 ~ 60v x 10A = 600w cont. 900w max 36 ~ 54v x 15A =810w cont. 1080w max Using 10A continuou...

Ive been looking at the options , the 30A 1500w power i like the lack of case I don't. The 50A has a case but its too large for my need This 1200w version might fit with the 350 mxus / 500w controller. To limit the battery to its 15A con. rating with the 48v bat , 54v to 60v would be 600w steady out...
